I installed a new alternator 170 amp. it seems to be working great. it drove to the gas station, but then for the first time in years my car wouldnt start and i had to roll start it today. ive got an optima yellow top battery.
I have upgraded the battery ground, but have not upgraded the alt to battery wire or the engine to chassis wire. I was testing out my alt and was cranking out music, my speakers pulled about 60 amps and the speakers started to get fuzzy and quiet, so i turned the volumn down and revved the engine out of instinct, and it went away before i could figure out what was going on. I know this is probably a stupid question, but is it possible i blew some charging fuse or something? voltage shows 14.5 when running and was showing 11.5 when it wouldnt start. Does the wire from the alt go straight to the battery, or does it split or get fused at any point? Happy to give any more info, i just dont know what else you may need to know. Thanks |

How did you check to see that the alt. and battery were good because it seems very odd that getting a new alt. would make it unreliable firing up when you had no problems before.
