I have my new engine in, but while hooking back up the wiring, I forgot where the positive side of my battery hooked up to, one wire goes to the starter, the other is a real thick one not hooked up, anyone able to go out to there car and trace it and tell me where its headed? I have the small thin one hooked up to the alternator as well.

thanks

not for certain, but i think the big wire goes to the starter....

i can't check till i get home. damn work.

 

hmmmmmm .... hmmm, its like a 2 gauge wire, It might go to the starter also but I already have 2 on it .... i shoulda taken pics before I dissasembled lol. Im not sure if it would reach, but would that one not being hooked up cause no power period? heh, I open my door and get no electricity. Appreciate your help

 

did you get the ground wire?

 

i've got my chiltons here, and it shows the negative to ground, and on some 3rd gens, there's 1 positive cable to just the starter, and in others there's 1 to the generator, and one to the starter. on the engines with 2 positive wires, the black goes to the starter, and the black and red, or just red goes the generator.

 

Which ground the one that goes into the adjusting plate for the alternator? I believe so. Im just a little confused I guess, How does the instrument panel and what not then get its power then? I will have to take a picture of what I am talking about I think

 

I mean if I had no engine In my car and didn't touch any of the electrical things should my dome light still be on?

 

what year and engine did you used to have, and what are you putting in?

 

1987 camaro, had a 305 with a 4 barrel carb
I put a chevy 350 block in, with the starter from the 305 so I thought nothing electrical changed.

 

i'm trying to read these wiring diagrams, but it's like trying to read chinese.

 

ya, I have my haynes, I looked up to see how the power gets to the fuse panel ... that was fun oh wait ... it wasn't I will be able to fiddle more tomorrow after work hopefully I will be able to get everything working so I can drive my camaro again.

 

from what i could tell from my car, which is a 86 2.8, so it's probably different, the negative battery cable goes down to ground on part of the passenger wheel assembly. and there is a large cable from the positive terminal that gets split, one goes to the starter, and the other a smaller one goes to the alternator. my guess is that the other wiring from the alternator goes to the fuse box inside the car and runs the appliances. i'll try to look some more tom.

 

If it's the positive battery cable, it goes to the large terminal of the starter solenoid. There should be some smaller wires there also; 2 is pretty typical.

 

thats what I was afraid of lol, looks like i get to pull the starter off again to rewire it, cant really reach it well without it off. thanks, Will try that tonight

 

Much easier to do it with the starter on.

 

i have a 4bbl 305 and the negative of the battery hooks to the bracket for the alternator same with the little wire. the positive goes to the starter.
