MC8 Alternator overcharging

[junkman42]

Jerry, thanks on the headsup on the regulator, I ordered one to see if I could update mine.  I have as of yet not been able to find My regulator, I suspect it is behind the propane tank in the right rear cargo bay.  I am sure on a rainy night I will get to find it, LOL.  John

Got the regulator.  Can I just put the battery, ignition and sense circuit on one wire?  Just make sure I use the the main battery cutoff switch so it doesn't drag the batteries down.

Yes you can combine battery & ignition only if you used OEM bus's relay as shown Diagram A in your instruction sheet...otherwise jump or remove relay & separate ignition wire to panel shut down switch.
About the optional sense wire...this a great feature for buses because of extra long alternator's charge wiring to battery that will vary voltage under load between both ends (alternator's P terminal to Battery + post). The purpose for "sense wire" is to get the actual voltage right at battery's + post for optimum state of charge level. There is no load but only voltage in sense wire.
If you didn't get that instruction sheet with part....you can download the following link:

2)   50DN to 50VR Circuit system on page 129 (same as instruction sheet)

FWIW
