Alternator Question

[155dB5.0]

I belive my alternator is dead....dont have my volt meter with me, but i started the car then un-hooked the alt from the batt and there was no change in voltage on the dash at all. Before i put it away for the winter was runing at about 8-9volts and would not move at all. Am i safe to assume the alt is tost?? Also is it worth rebuilding or just get a new one.

should have been putting out 12 volts. I would would chuck it and upgrade to a 3g alternator.

yea i agree, i already have a g3 on it, are they any cheep spots to get a decent one? Just want to get it running and dont run any stereo equipment or extra batts like i used to.

Did the fuse for the 3G blow, or did the sense circuit's fusible link blow?

Have either the entire system checked at a parts store or take the alt in for a bench test.
Your battery has probably seen better days if it was left discharged over the winter.

Just because a part is new doesn't mean it's good. I've received brand new batteries that failed a bench test before I even walked out of the store with them.

I'm not sure what you're asking regarding the schematic. Maybe this will help:
