Why did the fuse blow on my cigarette lighter?

Recently, the fuse for the cigarette lighter blew when I put in a car charger. The fuse powers the cigarette lighter as well as the radio and I think the backlighting on the air conditioner panel. I tried replacing the fuse (15W) and it blew again when I put in the charger. This happened once or twice more.

What should I do if my cigertte cigarette lighter blows?

The cigertte lighter has never worked so I thought it was about time I attempted to fix this. I removed the fuse (20amp) and found it to be blown. So I thought that i’d replace with a new 20amp fuse after checking the manual and online to ensure the fuse rating is 20amp for my model/make, it blew instantly.

Can you test for a faulty cigarette lighter?

Yes, first thing to test is for a faulty cigarette lighter assembly. Disconnect the wire from the back of it and see if that removes the short. If not the fault is “upstream” between the lighter and the fuse. Apart from a previous-owner “mod” it’s possible that the wire has been chafing against the vehicle chassis and is now bare.

How many AMPS is a cigarette lighter fuse?

Under normal circumstances, a cigarette lighter can be expected to draw roughly 10 amps, and cigarette lighter circuits usually have 10 or 15 amp fuses. This allows you to plug in phone chargers and other devices that draw less than 10 or 15 amps, depending on the fuse in your specific vehicle.

What happens when a fuse is blown on a cigarette lighter?

as mentioned on some other answers for blown fuses: if the fuse is blown, which usually indicates that there is a short-circuit, then replacing the fuse does not solve the short-circuit problem, and the new fuse will get blown too. – Florian Castellane Mar 22 ’17 at 14:55

This happened once or twice more.

What should I do if my cigarette lighter fuse keeps blowing?

It may seem like the easiest solution would be to simply replace the 15 amp fuse with a larger fuse, but this is actually very dangerous. While the wiring in the cigarette lighter circuit may be capable of handling a little more than 15 amps, there’s no guarantee that it actually is.

What causes a 12 volt cigarette lighter to stop working?

Even if your 12-volt device, charger, adapter, or inverter is designed to draw less than 15 amps, it’s still worth inspecting the plug. If the plug is broken, worn out, or has something stuck on it, plugging it in may cause a direct short between power and ground inside the cigarette lighter socket.
