John, if you have a 24 to 30v (not ctritical) transformer and a motor
starting capacitor you can "rig" a testing circuit.
Start with the brake terminals (1 and 2 IRC) and listen for a loud clunk
when the brake release is energized. Then the voltage is applied to the motor
terminals. There are three motor leads, left, right and common. The
capacitor connects between the left and the right leads.
An ohm meter will confirm proper operation of the direction potentiometer
as the motor turns.
If you can locate a copy of the control box schematic, it would make the
job identifying the various terminals easier.

It looks like the unit I have is a Ham-M Series 4 made in 1966. Under the
bottom pole mount section was stamped " 4 6 0 6" which is said to mean
Series 4,made in 6th week of 1966". And all this only if I am interpreting
it correctly. It'salso known as the Ham II I think.
Manufacturer was Cornell-Dubilier and according to Norm's FAQ's a Ham-M
used a single-levered control box with a meter. If anyone has a spare, I'm
open to offers.Right now I can't really test this thing and for all I know
it may have problems.
Thanks to everyone for the input. Haven't used a rotor since a kid so it
was fun tofollow this out and revisit this brand.
73, John
