Before I start up my 1945 Model B with its newly rebuilt generator, I want to be sure I get it polarized correctly so I don't screw it up. I found a discussion of this from last year, but the procedure described involved the light switch. But my B has no lights and therefore no switch. There is a regulator, not just a cutout. The setup is like this: Generator F terminal to Regulator FIELD; Generator A to Regulator GEN; Regulator BAT to Ammeter -. So what's the procedure here?

the B ternimal goes to the ampmeter. the other side of the amp meter goes to the battery terminal. if you run to the + terminal and ground the negative side, you have a negative ground system. if you run the wire to the negative terminal and ground the + you have a positive ground system. ALL Bs in the begining were 6 volt positive ground. do you know what you have? is the generator 6 or 12 volts? once all the wires are connect you need to touch the B and A terminals together for a second with a jumper wire to set the polarity. next start the tractor and see if the amp meter is working.

All is 6 volt. It's positive ground. This sounds so simple even I should be able to handle it.
Many thanks.

your tractor could have been converted over the years. when i said ALL i ment from the factory. they also put cutouts on ALLl of the B. since you have a regulator, i questioned ifit stil has the 6 volt battery or if it was chanaged out.
