97 Jimmy Alternator Question

[n.o.r.e]

My freaking battery light keeps staying and and my car eventually dies (volt goes to red yadada). Well i replaced the alternator from J&B (local junkyard), got it tested at auto zone, its good, prior to replacing my alternator I had my battery checked at autozone ALSO and they said it was good, took a charged yadada, replaced the alternator yesterday, was running fine, volt was good. Started the car today, voltage was normal then halfway driving I notice the battery light on and voltage dying..turned the car off and dead, got a jump battery light still on, made it halfway home..died, got another jump let it sit for a minute battery charged a little, but battery light still on died when i parked. OK thats the story now my question is...

 

WTF IS WRONG WITH THIS CRAP!

 

Could I have a loose ground somewhere? Anyone know where the ground for the alternator is? Could the power wire be burnt out? I dont have a volt meter to check. Could the fuse be bad? Anyone have the diagram for the fuse box?? Any help would be good..Already know the alternator and battery (MAYBE) is fairly good... uugh

Could be a loose ground, or maybe even loose power wire. The ground for the alternator is the engine block mounting point. Did you clean that up prior to installation? Maybe go around and check all the connections on the main wires between the battery, block, and alternator; take them off and clean the connections too. Maybe someone will have something more specific, but this can't hurt at all.

Could have a bad battery. I shorted out cell will cause excessive load on an alternator and blow it out.
