IF the diodes are in the regulator, I had planned to buy this...
Voltage Regulator (80 AMP) - Bosch 30091 | FCP Euro
It would be nice to bump what I believe to be a 55 amp alt up to 80 amps...
Why do you say it is a mis-match? The alt came off a OM617, same as mine. It has the same plug on the back.
