There are ten wires in my exciter. 1945 10ee MG.
there are two windings with 4 wires each and two wires for the brushes
right now i am getting about 112v dc out of my exciter but the voltage drops significantly when i start the spindle at the highest RPM
it drops 30v. sometimes the spindle starts sometimes it doesnt and the contactor drops out.
FA relay doesnt operate but that is a separate problem
I have an electronic 120vdc power supply that will start the spindle at all speeds flawlessly when i use it in place of the exciter.
Can anyone tell me how the field windings and the brushes need to be spliced inside the exciter for proper operation?
Previous owner had it completely wrong. I have to start from scratch.
I saw the hand written schematic that is posted on PM from peter222 IIRC. But i can't figure out the orientation of the drawing.
This is a piggyback exciter
Thanks
