Is there any way to increase the voltage without to change the diameter of the alternator pulley ?
I note that in "ralenty" the alternator just give me 13V, obviously more speed, more voltage. I have the old style external regulator.
The alternator is a delco remy 12v. Is there different pulleys diameters?
thanks
