Ok, im having problems with my charging system on my car, my alternator isnt charging. im running a Speedpro and i think i wired it right, but its still not charging. i've even went to the trouble of changing my alternator for a new one, but thats still not the problem. Here's how i have it hooked up...
Black/Yellow wire - Ignition
Blue/White wire - Battery light on the gauge cluster
Thick White wire - Fuse box under the hood

Im running an OBDII alternator and im not running my stock ecu anymore. If can someone help me out and if you see what im doing wrong, please help me out. Thanx.

 

the wiring you have is correct. Have you tried testing the voltage regulator?

 

I dont think i have, where is that located and what does it do? Do i just check to see if im getting enough voltage on it? thanx dude.

 

have your car up to temp and hold the revs up around 3K and jsut hold it there and check for voltage at the battery and it should be at least 15.1.

Also try the easy things first like the #24 15A fuse under the dash

also check all your connections, there are few wires on the alternator so they might be easy to spot.


I had to wore in a couple DFI systems so i get used to this sort of stuff.
What are more of the symptoms. Do you have a battery light, is it not on when the car starts but slowly looses voltage and comes on.

i believe all the fuses are good and i did check the battery voltage and its not holding, it keeps dropping the longer the motor stays on. I will re-check again monday and let you know, thanx man.
