That's right Doug, it's for one of the universal motors. Mark sent me a pic
of the
resistor, he told me that it had four taps but only two were used and looked
to have
always been that way. It's about six inches long and wirewound as I
expected. In the
Look for The Dog Book, in the motor service section, it says the resistor
was placed
in series to drop the voltage to an ideal of 32 volts. Not to exceed 36v. or
drop below 30v.
("As measured with a DC voltmeter"). I'm sure Mouser would have what he
needs but I do
not know how to determine just what he does need. I'm glad you saw this
thread, as I'm sure you
do know what would need to be used. He didn't mention any other resistor
being in the unit.
My experience has been with the induction motors. Hope you can help him out.
