Hi Guys...
My 66 C30 Tow Truck has a high output alternator. Everyone always points it out when I have the hood open.
I just started to smell rotten eggs, so I tested the volts at the battery and it reads 16.68 volts. I am assuming the regulator has gone bad.
The problem is, I am not sure where either the alternator or regulator came from. I assumed they were an upgrade from the factory, but have been told it was added by the tow truck manufacturer.
The regulator is not stock, it is bigger, aluminum and has fins. Can anyone help point me in a direction of a fix? Do I need to know more about the alternator to find a compatible regulator? Can I use a stock regulator?
Right now I am going to try and unplug the alternator so I do not burn-up the new battery.
Thank you in advance for any help... Russ
