-I get the same readings with or without a load.-

Bilge- Okay, and I assume that you are using a Digital Multimeter to read this.
Eisboch raises a valid question.

If you don't have one, I highly recommend my best friend, a Fluke 77 DMM.
Cheap meters are dangerous and a waste of money.

So...tell me about your voltage regulator...do you have a manual voltage
regulation knob? Or is it one of those solid state arrays?

It'd also help no end to know the excitation voltage of your genny. Voltage is
a function of how intense the magnetic field whose lines of force are being
broken.

I'll wager that in your gennie, the rotor is the electromagnet, and the stator
is where your grid is connected to.

Since you assert that you have no brushes on the critter, I'm assuming that
you have no slip rings, so the rotor is excited by an amplidyne.

We're hoping that your booger is in the external field excitation circuit, not
in the windings themselves...that might be...bad.

BTW, your gennie does have an anti-condensation heater in it, yes? A simple
heat strip or "burger light" can help you avoid no end of truly nasty
hemmorhoids. I've raised resistance to ground on crane motor-generator sets by
orders of magnitude after "baking" the puppies for 24 hours -from 1.5 megohms
to ground,(panic soon time!) to 500 megohms...saved the company a whole heapin'
****load of cash...none of which I ever saw, btw.

G'luck;
