Voltage Regulator for Merc 502?

[kevnmcd]

Does anyone know if the voltage regulator for a 1995 Merc 502 is internal to the altenator or external? If it is external....where is it? Thanks.

I'm 99% sure its internal. Its a GM type alternator, right? If so, the integral type plug has the 2 pins at right angle(90 degrees) to the shaft, the external type, (last used in the mid 70s)has the pins parallel to the shaft. Hope this helps.....Moneypitt

In case anyone is interested, this is what I have found out. It is an external voltage regulator that is mounted to the back of the altenator. It runs about $75. :D

Convert it to a GM integral. Simple to do, and a hella of alot cheaper...
