Electrical question(s), CJ-7

My 1976 CJ-7 has been sitting for about 3 years (hasn't moved). We got it started today after purchasing a new fuel pump and filter. Now we are working on getting the lights to work.

All the lights worked before it sat for so long. We played with the fuse box, and none of them appear to be blown.

The tail lights are working when the lights are "on", but the headlights are not functioning and the one of the running/turn signals works. Any suggestions on where we should start?

Should we just get a whole new wiring harness?

Thanks!!


BTW, it has a 304 and 3spd transmission, 4" lift w/ 35" Dunlops.

Re: Electrical question(s), CJ-7

I had an old Chevy Blazer that was sitting for about 2 years and I had about the same problem. After sitting for awhile you have to check to make sure Mother Nature's little friend, rodents, haven't chewed your wires anywhere. I found out that they like the bigger ones more than the littler wires. So, check the wires that feed the headlight relays. L8r,

Re: Electrical question(s), CJ-7

yeah the floor dimmer switch on mine got caked with mud. i spent a few minutes with it on the wire wheel and it works again.

when i first got my cj the headlights didnt work and it turned out to be the ground coming off the wiring harnesses on the bulbs. just invest in a good test light. i've used mine tons on my cj.

Re: Electrical question(s), CJ-7

I had the worst headlight problems ever. First they were fine, but then after a few months of owning it they would just go out. I'd be driving, hit a bump, and voila no lights. So I stopped driving it at night. Then one day I park it for the night and all of the headlight wiring melts. I had a short in the dash somewhere which caused the headlight switch to short out. There is a breaker built into the switch. So the few things I would check out would be the headlight switch, the dimmer switch, and then just follow the wires from start to finish to see if they are damaged. I am in the middle of replacing all of my wiring now. If you are going to get a new harness get one made by Centech. A few people on this board will agree with me on that one.
