OK, 1st off
THANKS for all the help.
I took the contactor apart, resurfaced the nasty, vibrated to death,
mating areas, made up new copper goodies and had them silver soldered.
Thing is quiet as a church mouse (whatever that means) now. Machine is
working again for less than 400 bucks rather than the OG $3000.00 it
was going to cost for a new contactor and aux's.

Thanks again for the help
