How do I tell how many amps my alt is? After I changed my belt yesterday my system drains my alt pretty bad and it never did this before. I think it's got something to do with the tensioner because the tensioner is old and moves a bit and when the voltage drops the belt sounds like it's slipping. Any feedback?
