My battery light's on after the alternator swap! I just put in a brand new battery and a rebuilt alternator from a '90 Teg LS (into CRX Si w/ a B16A). I'm getting 14+ volts reading on the voltmeter (that I also just installed) right from startup, and 14.5 volts on the handheld multimeter.

Also the 'check battery' light flickers when the car's taken up past 3000rpm or so, like it's turning on and off, though there's no voltage change... I already tightened the alternator belt also WTF??

as you rev past 3000, isn't voltage from the alternator suppose to go up a little bit?

 

u should not be getting 14.5 with the car just idling u should be getting that at like 1500 to 2000 maybe your alternator is over charging the battery thats why u might have the light flicking on and off and did u check all the connection and made sure the alternator is grounded properly that can be causing the problem

 

CRAP, that'll kill the battery huh? Damn.... I guess I'll have to doublecheck the grounding thing; I don't see how it can not be grounded, but... I don't know...

 

TTT

Any ideas? Bad regulator?

I checked resistance to ground - 0.8 ohms, and 0.8 ohms to power from power.

 

sometimes when the alternator belt is to tight the alternator over charges the battery and throws a code.

Only time you get charging system issues that are belt related is when the belt is too loose. Could have a crap rebuilt alt or the harness its plugged into might have some problems(broken wire,etc).
