1991 Civic. d15b1.
Changed my Alternator and battery 3 days ago. Car is dead again, what could be going on. Ive tested the alternator and the voltage fluctuates between 12 and 14 volts. what could be causing a drain, or what ?
Anyone ever have this problem, I cant keep getting a jum p for my car. and the funny thing is I cant even pop the clutch in gear to get her going ?

 

its most likely not the alternator unless its hooked up wrong. most likely you have a parasitic drain. my best advice is to take it to an automotive shop that specialise's in electrical.
parasitic drains can be a real pain to find. get a volt ohm multimeter and start looking but its best to have a shop do it.

diodes in alternator?

 

Did you check the charging voltage while it was on the car? Did you check the chassis ground strap to see if it's clean from corrosion and tight?

 

do a paracitic drain test that might lead u in the right direction also check ALL grounds in the engine bay any kind of corrosion or loose grounds could be your culprit.

 

Just because you have a new alt. doesn't mean it's good,even if its changeing right while it's runnin it could kill the batt. when off.I would bring it back and try another.
