Cigarette lighter fuses, like all car fuses, blow when the circuit draws more amperage than the fuse is designed to handle. ... And if the problem in your circuit is actually some type of short, putting in a larger fuse may cause the wiring to heat up to the point where it could melt or even cause a fire.

What would cause a fuse to keep blowing?

First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. ... A mis-wired lamp, for example, can cause a short circuit and blown fuse if it is plugged into an outlet.

Why does my 15 amp fuse keep blowing?

Having too many devices plugged into a circuit is the most common cause of fuses blowing. ... When a hot wire touches either the grounding pathway or a neutral wire, it results in the circuit shorting out. This is what commonly occurs when a mis-wired device is plugged into a circuit.

How many amps can a cigarette lighter handle?

If the air compressor uses a cigarette lighter style plug, then amperage is typically 10 - 15 amps. If the small DC 12V air compressor has direct battery connection clamps then the maximum current draw is typically 20 to 30 amps.

Can you replace a 15 amp fuse with a 20 amp fuse?

It would not be a good idea to replace a 15 amp fuse with a 20 amp fuse. If you do and you actually load to circuit to more than 15 amps, you will shorten the life of the insulation and increase the risk of a fire. ... It would not be a good idea to replace a 15 amp fuse with a 20 amp fuse.

What happens if the battery fuse blows?

Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won't start.

Why does my 10 amp fuse keep blowing?

The only reason a fuse will “blow” is because of a short circuit. That is a point where a wire connects directly to a ground and more current tries to pass through the wire than it is designed to handle. At that point the fuse will blow to keep the wiring from being damaged.

Can a blown fuse drain car battery?

The fuse can not drain anything, it must be the wires or the device that the fuse is for.

How do you know if a plug fuse is blown?

Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.

What happens if I put a higher amp fuse?

If you replace a fuse with a higher amp one it will work but create an unsafe circuit. It could cause a failure of the device burn it up, start a fire. The fuse is designed as a safety device. It should not only be the correct amperage but also the correct voltage and fast or slow blow.
