Alternator/Voltage Regulator problem

[Kurt Horvath]

Royal,

Yes I did have to replace the relay/solenoid. It did fix the problem.
Generally they are expensive and hard to find $400.00 PLUS $'S. I
found a great source, after I bought mine somewhere else---
Eaton / Cutler-Hammer # 6041H105 for $115.35

It's not hard to replace. Remove power from the relay/solenoid, just
follow the ground to the frame and unhook it then follow the hot,
(RED), to the shunt just below the relay. take all the wires off.
Remove bad relay/solenoid then just reverse the process and you
should be good to go. I did the swap myself and I'm not that happy
working with Electricity of any kind. If you need more help just ask
these guys will fill in the gaps.
