Interior lights

The 10A fuse under the hood that is for my interior lights keeps blowing i cant even put a new one in it just blows any suggestions?

You've got a short.

Unplug each device on that circuit, check if the fuse does not blow right away, and then plug each device back in, and see which one causes the fuse to blow. Investigate that device/wiring.

thanks i was afraid thats what i was going to have to do but oh well .

try a 20 amp. if it blows, you've got a dead short. if it doesnt, start looking for the smoke. crude, but effective, and wont be enough current to do any damage.

There is a good reason why it's a 10A fuse instead of 20A -- so wires don't melt or other things create an arc.

Also do you have fog lights or something that you taped off the lights? that can cause things to blow, if so just put a bigger fuse in and it should fix the problem

No fog lights but i tried the 20A fuse a few days ago and it blew right away so i guess i get to start tracing back everything on that cicuit with a multi meter

when the rated fuse blows try a bigger fuse? That is the worst advice you could give a person. I have a better one, just jam a penny in there so it will work.

But on a serious note, the only way to find the short is to do as Josh stated.

i've used this to find shorts on cars nothing else would. like a trailer light converter, that the owner didnt know was there, no visible wires, which kept blowing taillight fuses. tracing all the wires would have taken hours. popped in a 30amp(it was a 20), 5 seconds later, found the shorting converter, buried under a rear interior panel. wasnt anywhere near the rest of the wiring for that circuit. tracing wire doesn't pay very well on flat rate. if a circuit is designed to support 10 amps at a possible 100% duty cycle, running 20 through it for a few seconds wont hurt anything. and if you have anything other than a dead short, you can spend hours looking for the wire barely touching another, or the chassis. if, however, like this, the larger fuse blows instantly, you know you've got a dead short to ground. you can use a lightbulb as a short checker in place of the fuse. remove the loads from the circuit, put the bulb in, and it should light. when the short is removed (by unplugging/ etc.), the bulb will go out.

Thanks man i'll try that
