How to Polarize Generator with Cutout Relay

[Noah H.]

Hello,
I am going through the electrical system on a 1939 Farmall H that I recently bought, and I know that I need to polarize the generator. The tractor has its original 6 volt, positive ground electrical system with a cutout relay, NOT a voltage regulator. I can’t seem to find a video on how to polarize a generator like this with a cutout relay - because it uses a cutout relay, it is a 3 brush generator. Does anyone know how to polarize this type of generator?
Thank you!
Noah

Momentarily jumper across the two terminals on the "cutout".

Negative on battery to the A or G terminal of the generatorl

Good morning Noah, good question here’s my answer how to polarize a generator that used a cutout relay:

Use a jumper wire to momentarily flash from the battery’s neg post to the ARM post on the generator and you should get a small spark. If alls well and wired correct same things accomplished by jumping bat terminal to gen/arm terminal on the cutout relay. Do this BEFORE start up
