I'd check the brushes/brush holders in the alt & the green wire from the alt to the reg that it ain't grounded. Mechanical reg I'm assuming

I pulled my alternator out to replace the fuel pump, when I hooked it back up, I keep blowing out the voltage regulator. I have blown out four of them. I am at my wits end, I can't figure out what is wrong. Everything seems to be correct in regards to voltage at certain points
when the ignition is in the run position, but when I turn the ignition to start, it blows the fusible wire in the regulator. Any help would be greatly appreciated. 
You do know you can simply replace the blown fusible link int he regulator? I typically get one strand of wire from a wire and use that as a fusible link.
As for it blowing, the line to the alternator is probably being grounded out. Either the wire itself or the alternator is doing it, as mentioned. You will need to preform some resistance measurements, but seeing as to how you just replaced the alternator... I would look there first.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
