wiring help????

[race200sx]

I say wiring help because that is the horse ive been fed. It is also a factor in the ignition/electrical system. I dont mind being called names because i deserve it for jumping in this with no common sense and just blind ambition.

Anyhow, this is what is wrong:

Battery is new optima(installed by me today when i bought car)
alternator isn't working(could be faulty wiring)
Turbo timer works 1/3 of the time
battery light stays on


Those are the mjor points of discussion. I was told that the wiring was righed by a person before the owner that sold it to me. The last owner(guy i bought from) fixed the issues or not.

I know it runs off the battery and doesnt charge at any rpms. I unhook the ground from the battery terminal and car dies(alternator failure). My dad recommended a bench test for the alternator to see if the wiring is the issue. I think the same.

Based on what info i was given and observed what is the most probable indicator?

Again, sorry for the lack of inspection prior to buying the car, but it happened.

soooooo start by removing the alternator and taking it to autozone for a test to see if its functioning. then report back.

your alternator isnt working?? dude, replace that shit. even if it is actually working, that things like 20 years old. buy a quest alternator anywhere, its cheaper and holds more voltage.
check your fuses, relays, harness, grounds. make sure the battery is charged, duh.

and please dont be a bitch and make any more posts like this. or else i recommend you get the fuck out. good luck

Ohhhh, i knew you would say that :)

That is the objective. I just was impatient and wondering if anyone had any experience similiar?

Also, i have a obvious winding noise in 2nd gear. Any ideas? It doesnt happen in the other gears.

Thanks guys
