Broken Powermaster alternator.
This was the first alternator I bought for my car when I was reviving it and it never worked right. I’ve sent it in to Powermaster to get repaired 3 times, and they never got it right.
First it would drain the battery overnight if left connected, then it didn’t put out any voltage, then it worked right for a week and stopped charging again.
Not sure if it’s something simple or just a lemon. I have moved on to a different brand and given up on this one.
Maybe one of you can figure it out.
Has less than 100 miles on it.
Internally regulated
Single groove pulley
$40 obo.
Buyer pays shipping.
A new one is $150
One of the two tensioner bolt holes is stripped, and I stole the through bolt spacer out of it for another alternator.
