re wiring 81 280zx need help!


Recommended Posts

im pretty much done rewiring my 81 280zx because the guy i bought it from was an idiot and cut out all the wire harness'. but im having problems with the alternator. one of the wires comming from the T connector is not wired up. when i got the car it was wired to the battery, but about 2 days after i got the car it melted on me and almost cought on fire. can anyone tell me where it is suposed to go?

sorry for the poor description. here are a couple pics, not very good ones but maybe they will help a little bit. i took pics of the T connector so u can see what im talking about. its the only plug on the alternator. one wire from the T connector goes to the batt. but the other one is a mystery. Ive been told it goes to the ignition switch but i tried that and it didnt work...

Here is the terminal descriptions of the alternator.

Which one is burning S or L? I'm guessing L? Sounds like it could be a bad alternator.. You can leave it disconnected and have it still charge but you need to rev the engine to "self excite" the alternator.

i believe it is L and that makes sense because the car ran for a while yestarday with the wire disconnected while i was revving the engine. but id like to know where it goes so i dont have to worry about it. since i dont have the factory wire harness and an aftermarket ignition its hard to find a home for the other end of this wire. any ideas?

it does test for that, and the alternator tested good. so i guess what the next question is, is since i dont have a wire harness, should i just wire it to the light and then to a fuse that goes to the acc, stud on the ignition switch? cuz thats how my fuse block is wired. straight from the acc side if the switch.... hmm any thought?

ok so, i tried running the power to the batt. side of the ign. switch, and ran power to the volt gauge. im charging at about 10-11. but only when i rev the motor like you said, to excite the alternator. but still wont charge past 11 volts. any other ideas?

 

P.S. sorry if i sound repetative, just really wish i could get this car running. thats the only thing i have left to figure out.
