(ET) All fixed

[Chris Zach <czach computer org>]

Swapped out the contactor pair with a spare set and the tractor is 
working perfectly again. I'd still like to find that other ground fault 
though; any suggestions on how to track one down? The only clue is that 
it's there even with the main disconnect off, and it's pretty persistient.

Another thought: Pulling those contactors is a real 14 karat pain. 
However I do like the fact that one can fix just about anything on a 
contactor based elec-trak with a meter and a set of wrenches.
