The lights seem to go dim but to be honest not really.. But the numbers do go down.. From like 14.3 to about 12.8 or so. But just the other day when I mentiioned I fixed the problem I turned on the lights and it held from 14.2v to 14.1 and I figured I fixed the problem. But then it does it again!

Bump

Update again.. Freaking car went back to those wacky readings. I swear I need to ignite this car with a flamable liquid!

Tial 50mm bov all the way... I say buy it and love it.. :)

During my rebuild last year I replaced the battery to chassis ground the back of the head to body ground with 4 guage wire.

Well I guess I fixed the issue. I just came back from the auto parts store after picking up a new battery terminal for the positive side on the battery and I just redid the ground wire that connects to the chassis and tranny housing and the drop in voltage is gone. I tested it bu turning on...

Bump...... Anyone?

I agree no need to buy the mr2 alternator.

Ok kool I'll try that as soon as I get back home tonight. I assume I need to do this when the car is running.. And just by chance what voltage readings should I be looking for as far as normal readings and abnormal readings.. Might as well know what to expect. :)

Well the alternator is new. And the battery is brand new. Just got it today. So I don't thinks its either one of those things. How would I check the voltage output of the alternator? Sorry for that newbie question..

I've been trying to determine what voltage numbers I should be seeing.. Im trying to find someone with a safcII installed in their car to see what volt readings they see on the monitor window when batt is selected. I get 14.3volts when the car 1st comes on then if I turn on my head lights the...
