My alternator gave up and I need one to fix my car over the weekend. My local parts store has one in stock.

But I want to upgrade to an 80 amp alternator.

So, are there any distinguishing features between a 70 and 80 amp alternator. That way I can verify that I am buying the higher capacity one.

Thanks

HS
