Re: Weird electrical problem on Sidekick
My friends and I put together some parts last fall: the drievtrain from an 89 sidekick and the body from a 95 tracker.
The most noticable problems afterwards were electrical. The intermittent wipers would come on when you put on the right turn signal, which was not glowing as brightly as it should, either. This turned out to be a bad ground. The right front fender and some of the rest of the front clip had been replaced and the wire that was supposed ground that section was grounded to the replaced part, which itself was not grounded well enough. We moved the ground over to the "old" part of the body and the problem went away.
There have been intermittent issues with blowing of the main 40A fuse under the hood while starting, too. I haven't traced this yet, at least not to the point of being able to fix it, but it no doubt involves something grounding out that should be. For a while I would blow my taillights and rear sidemarkers out when I turnedd on the radio, but that was my own fault for the way I wired up the radio. Still it took me a while to figure it out and lots of blown fuses.
One of the guys in here whose a real whiz with circuitry will hopefully drop in and just tell you its this or that wire that needs grounding. It sounds to me (not an expert) that you have a loose ground under the hood somewhere. The wires on these older rigs can develop a lot of corrsion and stop grounding, even though they look to be sound. One might even be broken off. Check for connectors screwed to the body with no wires going to them and corresponding wires that dont go anywhere [img]images/graemlins/wink.gif[/img] You might do well to locate all the underhood grounds (especially in the lighting part of the harness) and take them off, clean them up, and put them back on. To make your search a little easier you could try jumping each of the grounds to a known good ground to see if you can get the faint glow in the lights to go away. Get a jumper wire and touch it to the connect at the end of the ground wire where it screws to the body. If you can get it to change the faint glow you know you;re in the right neighborhood, at least! You should also go along the entire length of the wiring harness to see that none of the insulation has worn through exposing the wire underneath and allowing it to ground against the body or frame, or another wire. That sounds kinda daunting if you havent ever really looked at the underhood wiring, but there isn't really all that much of it (compared to newer vehicles..yikes!!!) and you should be able to methodically cover all of it if you take your time. One *good* thing about it is that your problem is consistent. Whatever is wrong will still be wrong when you find it. Intermittent problems are no fun. [img]images/graemlins/AR15firing.gif[/img]
Now hopefully aftermarket4x4 or someone with lots of wiring experience will chime in and give a more well informed opinion.
hope this helps a little...welcome to the ORC BBS, too [img]images/graemlins/burnout.gif[/img]
