Hey everybody I'm currently trying to figure out why I keep blowing the 15a fuse in my truck 3 in less then 20 miles. So I'm going to go take out all the bulbs start the truck and put them back in 1 by 1 until the fuse blows again to see if it's a bad socket with a short. if you have any better ideas what's causing my problem I'm all ears. Well eyes in this situation. Thanks.

 

Yeah start with telling us what fused circuit it is. If you don't have the fuse box cover picture that tells the circuit names, take a photo and indicate which fuse is blowing.

For starters..

 

Get your multimeter out, pull the bulbs pull the fuse and check resistance to battery ground at the fuse box, check at the lamp sockets.. Lower the resistance the closer to the short.

 

Yes, you will need to tell us which fuse keeps blowing.

At this point, we don't even know if a lamp circuit is the problem. It could be a lamp circuit, or maybe something else.

 

headlight?
brake light?
turnsignal?
Dome light?
Dashlight?
parking light?

 

Furthermore. Is it supposed to be a 15 amp or was it a 10 amp that was blowing and the previous owner just upped the amps to "solve" the problem.

 

Would like to help but you need to tell us which fuse is blowing, and its location, under the hood, in the kick panel, drivers side, passenger side????
