keep blowing fuse
 

My 88 cab keeps blowing the same fuse. My left front fog light and the rear left tail light went out, so my first thought was the fuse. I found that the fuse for those lights were blown, so I replaced it and it blew again. I thought maybe I messed it up when I put it in, so I put another one in and it did the same thing. Any thoughts anyone. I don't want to get pulled over for something simple as that. thanks in advance.:confused:

You've got a short somewhere. Start by pulling the lenses on both lights and looking at the wires to see if they may have rubbed through somewhere.

K.i.s.s..I have had a light that was shorted out inside...after much frustration......the last place you look.......

What size fuse are you replacing it with?

I'm replacing it with a 5A.

Hmm
Side Marker lights are 5A.
Fog lights are 16A

Pull all of your left side marker bulbs out and put another 5A fuse in there and turn on the lights and see if it blows again. If it does, you will want to get a lot more fuses.

You get to find out which wire wore through or which lamp assembly is grounding out.

If removing all bulbs doesn't solve it, You will need an Ohm meter and check each socket connector (the little positive one and see which one is grounding.

Good luck.
