Voltmeter/Polarity indicator circuit diagram

[Robin]

Thanks Chuck-
That brings up a point that I have considered. This might be a cumulative
problem with a bunch of small leaks adding up. It seems that the powerwatch
itself is not the only culprit. I've capped the bare wires to the system and
plan on plugging her in again when I get some daylight.

Your troubleshooting procedure seems laborious, lots of trips back and forth.
Any way to check the system with a voltmeter? If there is voltage on the
neutral, I should expect a decrease voltage between hot and white.
How about flipping all the breakers off, disconnecting all the whites, then
reconnecting and re-energizing them one at a time to find which one kicks it
off? What are my chances of frying myself that way?
