Thanks for the replies guys, Yes, I did see the MAD electrical stuff but I was really hoping to disturb as little as the wiring as possible to make this work.
I was wondering about the field wires if I had them backwards on the switch or if I only needed to shut down one of the fields.
If I only shut off one of the field wires, what do I do with the master cutoff switch, just interrupt one of them using the switch and discard the other?
Thank you, just saw your edited response
