92 sr-20 charging issues/ NEED HELP! Tried 3 different alternators & no luck~

[mosr20]

I'm getting 13.0-14 volts w/3 separate alternators...... (1 s13 jdm one and 2 usdm s13 alts that I made work/drilled out the threads)

The car worked fine before......

it has low voltage upon startup, but once I reved the motor to 3k+ rpms it goes to 14 volts or so ....

I figured it was just a bad alt so Iput in one I had from one of my parts cars...... it got the same result....... and the same results again with yet another alternator .....( both from 91-94 s13s)

I searched and can't find the solution....

i checked to make sure the ground to the alt wasnt touching anything like the ps lines......

I also checked fusable links and other fuses....

please help me get this straighted out.....!!!

thanks!

hey, not to make it sound like you dont know anything, when you try to start a car, the starter takes a lot of juice from your batt. after a while your batt should charge. if its not, check a ground wire somewhere. loose ground may be making some drain the batt.
