My alternator light came on, so I pull the thing, open it up and test the diodes, they look OK.

After reassembling it I spin it and something is hitting. On the rotor there is a thin metal piece that looks like an elongated diamond, this goes over the edge of the rotor.
I popped it back in place and it works again.

I don't know if that was the problem or not, but I don't rust this alternator.


So the question...
What is special about this huge alternator? does it put out more current? No one around here knows what it is as there are no part numbers on it and 1975 GMC motorhome isn't in their computer.

Where do I get a suitable replacement locally?
( yes I know Jim has alts, but the pics look like the small ones..)
