Why Does My Cigarette Lighter Keep Blowing Fuses?


If you’re a smoker and don’t have a lighter, a car cigarette lighter socket is a convenient accessory. Charge your smartphone or GPS device by pulling out the built-in cigarette lighter and plugging it directly into the socket. To fix your car’s cigarette lighter socket, you may have previously replaced the blown-out fuse with one of the same amps. A new fuse will not solve the problem of your cigarette lighter constantly blowing when you start your automobile. Instead, you’ll waste even more fuses by doing so. Something shorts out along the wiring of the cigarette lighter socket, causing it to blow its fuse.

An electrical fire can occur if the cigarette lighter socket’s circuitry catches fire because of the fuse. Fuse blowing is a common occurrence in automobiles, but there are several reasons for this to occur. The wires connecting the socket’s back might contact one another. Or if there is debris or metal stuck within the socket itself. The wire can be shorted using either of these two methods. This post will acknowledge why my Cigarette Lighter keeps blowing Fuses.

Why Does My Cigarette Lighter Keep Blowing Fuses?

Cigarette Lighters Blow fuses when the current demand exceeds the fuse’s capacity. In this case, the lighter’s circuit draws more amperage than the fuse is designed to handle, and the lighter’s wires are probably loose.

Cigarette Lighter

All automotive fuses, including those in cigarette lighters, blow if the circuit pulls more current than the fuse can withstand. Using more than 15 amps on the cigarette lighter fuse can cause it to blow. If you put in another 15-amp fuse and anything on the circuit continues to draw more than that, the fuse will blow again, and you’ll have to keep replacing it.

Although the most straightforward answer may be to replace the 15 amp fuse with a larger one, doing so is extremely risky. This circuit could carry up to 15 amps, but there is no assurance that it does so in practice. It’s also possible that a bigger fuse might cause the wire in your circuit to heat up to a point where it melts or perhaps starts a fire. A circuit breaker is an option. However, it’s a poor idea if there’s a short in the circuit, as this might cause the breaker to trip. Deliberately overloading the cigarette lighter circuit with one of these breakers is not recommended.

Where Is The Fuse For Cigarette Lighter?

The fuse for a cigarette lighter is in your car’s interior fuse box. However, many modern vehicles with non-smoking owners do not have a fuse for cigarette lighters.

 

If you’re looking for the fuse for the cigarette lighter, it’s likely to be found in the vehicle’s passenger compartment fuse box, which also houses fuses for other instruments. It’s a good idea to look in the owner’s manual to see if the fuse is listed there. When a fuse blows, your car’s wiring and electronics are spared damage. So, if the cigarette lighter fuse blows repeatedly, it’s a good sign that something is wrong and must be addressed.

Even the cigarette lighter socket wiring could be at fault if the problem isn’t solved. Every conceivable source of failure must be checked to find out what’s causing the cigarette lighter fuse to blow. However, it would be best if you did not attempt to increase the amp rating of the cigarette lighter fuse. The fuse box may be damaged, wires may melt, or even a fire may break out if you apply a bigger amp fuse to solve your problem.

What Amp Fuse For 12v Cigarette Lighter?

Usually, a 15-amp Fuse is used for a 12v Cigarette Lighter. However, some models can have different AMP fuses, so please check the information in your car manual.

Cigarette lighter circuits typically utilize 15 amp fuses, but you may check the fuse box in the car for confirmation. The next step is to examine how much current the gadget you’re plugging in consumes. Car auxiliary power was initially meant to provide electricity for an electrically heated cigarette lighter in automobiles. However, it has become a standard DC connection for supplying electrical energy from the car’s electrical system to portable equipment used in or around the vehicle.

Many devices, such as portable battery packs, air compressors, and inverters, may charge mobile devices. When in doubt, consult your owner’s manual before connecting the fuse to the cigarette lighter’s holder. To get an accurate reading, you’ll need an amp meter to put into the fuse and measure it. If you get away with it, you can increase the fuse size. It’s better to be cautious than sorry!

Almost all cars have at least one vehicle outlet. Some vehicles have additional power outlets, notably vans, which generally have one for the front passengers, one for the back passengers, and one for the baggage compartment. While the engine operates, the voltage outlet can rise between 13.5 V and 15 V. Car fuses of 15 – 20 amperes safeguard the 12 V power supply, which may deliver 120 to 240 watts of electricity. Hairdryers and toasters, for example, consume far too much electricity to be powered by an extra power outlet. A car battery can be charged directly from an external power source rather than through the ignition, which is more convenient but slower than currents provided via electrical clamps just on car batteries, which are more common.

What Is The Cigarette Lighter Fuse Called?

The Cigarette Lighter Fuse is called an Auxiliary Power Outlet.

The term “cigarette lighter outlet” can refer to various things, including an auxiliary power outlet, a phone charging point, or even a 12-volt outlet. Friedrich Wilhelm Schindler, a Swiss-Austrian inventor, designed and patented the electric cigar lighter in the early 1880s. Electrical cigar lighters and Zigarrenanzünder were marketed in German warehouse catalogs in the late 1890s and early 1900s. Cigarette lighters may have been renamed in the 1920s when cigarettes supplanted cigars as the most popular form of smoking. Patent 1,376,154 was awarded in 1921 for a so-called “wireless” and “cordless” lighter with just a replaceable element by Morris, Inc. Afterward; the igniter was physically withdrawn from the socket and put into use.

As vehicles became more common in the United States in 1925–1926, cigarette lighters became standard equipment. The Connecticut Automotive Specialty Company in Bridgeport, Connecticut, developed car cigarette lighters in 1928. By winding the cable around a spring drum, the reel-type lighters made it possible to remove the igniter unit and cable from the socket and use them to light a cigar or cigarette. The wires were coiled back into the detachable plug as it was inserted into the socket. Pressing a button or withdrawing the igniter of its socket stopped the circuit. In 1956, Casco invented the “automatic” detachable vehicle V-Coil lighter, which earned a patent from the United States Patent Office in 1960.

How To Fix A Fuse That Keeps Blowing?

  • Unplug all the electrical devices.
  • Locate the fuse box 
  • Replace the fuse 
  • Test your new set-up.

To begin, pinpointing the exact location of the outage is critical. Take advantage of this information to help narrow down which fuse is responsible. Flipping the light switches within every room is a simple approach to check which rooms have lost electricity. After that, switch off the lights and disconnect any appliances in the affected rooms. You may trip the electrical panel again if you keep everything on and replace the fuse, according to Angie’s List.

As the last step, you must cut off your home’s main power supply. You should do this procedure through your electrical panel to ensure your safety. Many individuals don’t know where a fuse box is until a problem like this occurs. Therefore, it’s essential to know where it is. According to House Method, fuses are found in older homes, whereas circuit breakers are found in newer homes built after 1965 or retrofitted with modern wiring. In most homes, the garage, the basement, or the utility room will have one or the other.

After that, you’ll have to figure out which fuse blew. The wire used in these devices is flammable and can melt or damage an electrical circuit if the current is too high. Electrical fires can be prevented with the help of these devices. A damaged fuse will have metal melting or the glass covering discolored; thus, you should seek that type of fuse. If a fuse has to be replaced, it’s critical to obtain a replacement with the matching amperage rating.

If you take your old fuse to your local hardware shop, they will have an exact replacement for you. As soon as the old fuse is removed, it’s as simple as putting in the new one. Once everything has been neatly tucked inside the fuse box, reconnect the leading power and verify that the circuit works. Turn on the lights and plug in the equipment to avoid overloading the circuit. If the fuse keeps blowing, hiring an electrician is probably best.

How Much Do Car Fuses Cost?

Car fuses cost from $5 up to $25. However, some modern expensive cars can have car fuses up to $100.

The cost of replacing a car fuse will vary depending on the fuse the vehicle requires. While most automotive fuses cost between $10 and $20, some models need specialty fuses that cost upwards of $100. Based on your selected shop, mechanics will charge you an extra $65 to $110 to replace your fuse. Even though your insurance won’t pay for routine auto maintenance, examining your policy is vital to ensure you get the best deal possible.

A fuse is the most prevalent form of automobile electrical protection component. They can be found in the engine compartment, a fuse box beneath the hood, or both. Additionally, the fuses in some vehicles may be located in unusual places. Whenever a circuit is turned on, the current flows via a fuse to the device connected to the circuit. The importance of changing a fuse is directly tied to the component or system no longer functioning. A radio or A/C fuse may have blown, but it is more likely to be a minor nuisance than a hazardous driving situation. When a fuse blows, check the car’s electrical systems out as quickly as possible to ensure maximum enjoyment and accuracy.

Can You Replace A Fuse With A Higher Amp?

No, it would be best not to replace a fuse with a higher amp because this can damage the electronics in your car.

Fuse replacements with more excellent amperage ratings are not recommended. The fuse has a specific amperage rating to ensure the safety of the circuit’s electrical components. A blown fuse indicates that too much current is flowing through the system. Several causes can lead to this, including a defective or accidental connection between two distinct circuits, a shorted electrical component, etc. If you’re having electrical issues, it’s best to take your car to an auto electrician.

Lights and motors generate heat when turned on, caused by the passage of energy across the circuit. Excessive heat must be kept out of your circuit. So, the fuses are in charge of completing that task. Fuses have a thin metal strip that melts if the amp rating is exceeded. The load amount, wire size, wire length, and voltage determine how much heat a circuit generates.

A circuit designer can determine the proper fuse size based on these variables. Because a larger-rated fuse is made to manage higher amp draws, installing one that is too large would result in increased heat inside the circuitry (in the event of a short). Excessive heat, charred wires, or components are the outcome. This can cause the fuse to overheat and blow before the circuit’s capacity has been met if the fuse is too tiny. As a result, each time the load is switched on, the fuse blows.

How are Cigarette Lighters and Accessory Stocks Different?

The difference is that you can’t put the cigarette lighter into a 12v outlet, but you can put Accessory Stocks into a 12v outlet.

The problem is that cigarette lighters were never intended to supply power to external devices. This was not the case when they initially appeared in automobiles. It wasn’t until “wireless” lighters were introduced that cigarette lighters could serve as both a lighter and a lighter. Although cigarette lighter sockets weren’t meant to supply power for other devices, they are not well suited. Their intended use, heating a bimetallic coil to a bright red hue, is the exact reverse of what you’d expect from a device designed to transfer electricity efficiently.

Ultimately, because cigarette lighters are supposed to grow extremely hot, it doesn’t matter if their fundamental design creates a subpar electrical connection because they’re built for that purpose. Cigarette lighters and accessory sockets are identical in powering gadgets like your cell phone. Therefore, there is no need to distinguish between the two. If you don’t know whichever one you’re dealing with, you can connect to any or all of them. A cigarette lighter cannot be plugged into an auxiliary socket, which is the only significant distinction. In the ideal situation, nothing will happen. Even in the worst-case situation, the lighter will begin to heat up. However, the socket will not be strong enough to handle the heat.

Can You Change A Fuse While The Car Is Running?

No, you cannot change a fuse while the car is running. Before changing it, ensure the fuse has an issue, find the fuse panel, test the fuses before removing them, and check the circuit.

The fuse blows to stop significant damage or even fire in one circuit when too much energy flows through it. Electric components that suddenly cease operating, such as a window that stops sliding up or down or a radio that stops working, are sure signs that a fuse has blown. Although it is unlikely that a fuse is to blame if an electrical component shows signs of deterioration over time, it is still a good idea to check the fuse frequently.

The fuse panel may be found in the vehicle’s owner’s handbook. In most vehicles, it is located under the steering wheel, just on the driver’s side of the dashboard. Remove the lid from the fuse panel to reveal a slew of distinct, color-coded fuses. The varied amperage ratings are denoted by these colors and the numbers imprinted on the fuses. Fuse diagrams on the fuse panel’s backside may show which electrical component is connected to which fuse.

The fuse puller may be found by removing the lid of the fuse panel and looking for a little fuse puller. Most automobiles include a fuse puller, but not all do. First, it’s possible to test the fuse before removing it, depending on the fuse, either a continuity tester or an ammeter/ohmmeter. Two metal tabs on the top of an unremoved fuse can be tested using either a test light or an electronic multimeter. Once you’re confident the probes are in touch and connected to the tabs, the fuse should have continuity (the test light will light up) or a resistance reading (that might read 0 or 0.001 milli-ohm).

Use the fuse panel diagram, your numbered color-coded fuses, and the owner’s handbook to assist you in calculating the correct amperage for your replacement fuse. Put the fuse panel back on the car after you’ve found the proper fuse and push it into the corresponding slot. Turn on the ignition and verify that the circuit causing the issue operates appropriately after replacing the fuse. If it’s still operating, it’s possible a brief surge blew the fuse has been solved if that is the case.

What Would Cause A Fuse To Keep Blowing?

A fuse could keep blowing due to debris in the socket, a faulty fuse, a damaged socket, a broken wire, a damaged circuit, or a ground fault.

If an outlet or a specific appliance is being overworked, users should be able to recognize the culprit. Visualize an outlet on a power strip plugged full of high-energy users, and you get the idea. Reduce the amount of energy that is being drawn from a single circuit. Unplug everything that isn’t in use or locate outlets on different circuits. This is a sort of electrical failure known as a short circuit. Due to the lack of resistance, an electrical current might go outside its intended route (circuit). As a result, there is a poor connection between the circuit’s two power conductors. It is caused by a “short” or “defect” in the power supply, which results in an overflow of current. A short circuit can even lead to the destruction of the electrical device responsible for it. As their name suggests, circuit breakers are primarily used to interrupt short circuits.

Unintentional passage of electricity to earth (ground) or contact with a grounded system component, including a grounding wire or an electric box, is known as a “ground fault” in electrical engineering. Direct contact with the ground’s weak path increases the risk of shock. As a result, GFCI outlets are commonly seen in bathrooms and kitchens. Problems in wiring and terminal connections, such as a loose screw, are the cause of arc faults. Your home may be equipped with arc fault circuit interrupters (AFCIs), which will trip a circuit in the event of an electrical spark. Both of the previous examples apply here. Even without AFCIs, your home should have been protected from this problem. Otherwise, look for damage and have an electrician come out if necessary if it doesn’t have AFCIs.

Many different types of fuses may be found on the market. Many have a similar appearance, yet their functions are vastly different. If the improper fuse was put in a fuse panel by you or someone else, but no one was hurt or anything was damaged. You’re in for a treat. It’s possible that whatever caused the fuse to blow may have resulted in significant damage. To avoid more damage, have an electrician come out immediately. Do not approach the fuse box at this time.

Does a foreign object damage the Cigarette lighter?

Yes, foreign objects can damage Cigarette lighters. For example, if a cigarette lighter touches a coin, it can cause a fire or electric issues. Any metal object can also get stuck in a cigarette lighter socket and cause additional problems.

Cigarette lighters frequently blow fuses for many reasons; one of the most prevalent is that something is stuck in the socket. Because the central pin of a cigarette lighter socket is hot and the metal body is grounded, it is surprisingly simple to short the circuit. Change holders or catch-all trays near the cigarette lighter socket in certain automobiles make it simple for a coin to fall in and cause severe injury or death. A short circuit might occur if the coin touches the grounded barrel and the hot pin within the socket.

Other metal items, such as paperclips or shattered parts from old phone chargers, can become stuck in a cigarette lighter socket. A cigarette lighter or 12-volt power adapter may not always produce a short circuit, but if you insert it, the fuse will quickly explode. If you find a foreign item in your cigarette lighter socket, you may be able to remedy it by simply removing it. Before entering the socket to remove the foreign object, remove the cigarette lighter fuse for extra security. You may replace the fuse and test whether it blows again when you’re done.

In some instances, it may be nearly impossible to locate this sort of short in your car. The radio, HVAC controls, or dashboard may have to be removed to identify the short. Automotive short-finding devices exist, but they’re not the type of gear most people have. Sometimes, removing the cigarette lighter fuse and running a new power cable to the socket may be more accessible.

Does Cigarette Lighter Work When Car Is Off?

No Cigarette Lighter Does Not Work When Car Is Off.

For any 12-volt accessory socket, the maximum amount of current that can be drawn is set in stone. To power up your cigarette lighter-enabled equipment, you must ensure it draws sufficient amperage. You may inspect your vehicle’s fuse box to see if your cigarette lighter circuits utilize 15 amp fuses. The next step is to examine how much current the gadget you’re plugging in consumes. In most cases, cigarette lighter socket chargers don’t cause a fuse to blow, but other devices, such as cigarette lighter inverters, could cause the circuit to be overloaded.

Check the plug even if it’s rated with less than 15 amps on your 12-volt gadget, charger, adaptor, or inverter. An immediate short may be between the socket’s power and ground if a damaged, worn-out, or plugged-in plug is inserted. Trying a new 12-volt charger and adapter may help rule out the possibility that your problem is with the charger you have been using, especially if you’ve only ever tried plugging in one device. Also, you might check the adapter with an ohmmeter for a short.

How Can You Tell If A Cigarette Lighter Fuse Is Blown?

A Cigarette Lighter Fuse is blown if an obstruction inside the socket and the charge itself is terrible.

A vertically mounted cigarette lighter socket is the most common cause of this problem since it makes it easier for tiny objects to fall into the socket. The cigarette lighter socket is blown. Non-conductive impediments prohibit charges from making contact. Conductive items like coins might blow the circuit. This implies that no electricity is being sent to the plug. The fuse may have blown, but the wiring is likely wrong. It would be best to eliminate the possibility of a defective charger. You may have a defective charger, a faulty device plug, or worn-out springs in the cigarette lighter socket plug, which are all possibilities.

Ensure there aren’t any obstacles in the socket before you try to plug in anything else. Grab a flashlight and peek into the socket with your own eyes. When a penny accidentally falls into a cigarette lighter or 12v accessory socket, it’s one of the most prevalent reasons for malfunction. Sockets can short out and blow fuses if this happens, but they can also protect accessory plugs from making contact and working correctly. If the thing in question is non-metallic, you won’t have a short circuit and blown fuse. An accessory plug can still be prohibited from making electrical contact by a foreign object, however Take cautious not to accidently short out the circuit by reaching inside it while it’s still hot to remove the instruction.

Are Car Cigarette Lighters Universal?

No Car Cigarette Lighters are not Universal. ANSI/SAE J563 is the standard for cigarette lighters in the United States, but it is not compulsory worldwide.

ANSI/SAE J563 is the standard for cigarette lighters in the United States. However, there are a few others worldwide. An accessory maker may create plugs that fit snugly since this standard specifies specifications such as the diameter of the receptacle. Automakers can use a second set of measurements to designate specific accessory sockets to the standard’s requirements. Instead of cigarette lighter connectors, these sockets take 12v power plugs like chargers, inverters, and other devices that adhere to this specification.

To determine if you’re dealing with just a cigarette lighter or an accessory socket, the best thing to do is examine the owner’s handbook or contact your dealer. There is a slight change in appearance between the two, but only by millimeters. If a socket doesn’t come with a cigarette lighter, you cannot know if it is compatible with one.

As long as most dashboard outlets are still intended to accommodate cigarette lighters, please don’t assume they are. For the most part, cigarette lighters and accessory sockets are found in the same places on a dashboard with many outlets. Similarly, other auxiliary sockets are under the dashboard, in the center console, and throughout the car. As a rule of thumb, though, never use a cigarette lighter in a receptacle. Only by calling your local dealer and the manufacturer can you be sure.

Conclusion

Most individuals have dealt with a blown fuse at some point. When something like this occurs, someone is always prepared. It’s likely that you, as a homeowner, are responsible. Blown fuses happen frequently. For most people, the old-fashioned fuses in their homes have been replaced with contemporary electrical panels with circuit breakers.

However, a “blown fuse” frequently represents various unanticipated electrical events, particularly those involving energy loss. The term “blown fuse” can refer to a wide variety of phenomena, many of which have nothing to do with fuses. As a result, you may be asking how to determine if a fuse has blown – an actual fuse. You’ll notice a charred panel and a melted fuse when you open the hood. We hope you have acknowledged why my Cigarette Lighter keeps blowing fuses.
