Hi friends,

I have this dyno in very nice shape. Everything moves easily and the commutator and brushes look great. I have a (very big) battery for 28VDC and would like to power this up before connecting to my newly acquired ART-13.  Other than applying the 28VDC, there are some contacts in the big circular connector on the dyno that I know I need to do something with to get it to start up. I know there are relays that run enable the 28V to the motor.

I’ve looked over several manuals and can’t quite figure out which conductors on this big circular connector I need to address. And exactly how to address them (perhaps just short them together?).

After a coupla hours looking at manuals and not zeroing in on what I need, any help appreciated!
