Thanks, John. I"ll print out your response and use it as a guide to do some more testing – hopefully today, maybe Monday/Tuesday.
It"s interesting the way the regulator actually changes the supply voltage coming from the generator. I tend to think of regulators as things that take a variable voltage (Vss) as an input and provide a fixed voltage as output, without affecting Vss – like a 7805 IC, for example. It never even occurred to me to regulate voltage by actually directing a change in Vss.
I tested the old regulator with 24VDC, and was unable to get either relay to actuate. I wasn"t too surprised, as there"s an awful lot of rust in there. I ran across an excerpt from “Wired for Success" by Randy Rundle, where he says “positive ground regulators will have copper-colored current and voltage regulator coils, while the negative ground regulators will have cadmium or straw-colored coils.” If he"s right, then I definitely have a positive ground regulator in a negative ground system. :-(
Anyway, thanks again for the advice. I"ll take another look and hopefully gather some more info.

"Barry Seiler, owner of Country Town Farm Supply store used to invite people up to the Johne Deere store. He would give hats and a free meal for everyone that brings a tractor." Elliott said while this
