I have been looking on this site for awhile and finally decided to register.
I have been restoring my 1945 Farmall BN and it is hard to find information. When I first got it in 2002, it had a primer coat and some parts were missing. There was no battery so I bought one and after 12years it went bad. It was sitting most of this years in my shed and now after all these years started restoring it farther. When it was running I never saw any indication that it was charging, the amp gauge stayed at 0. It had a voltage regulator mounted behind the control box on the gas support. I bought a new voltage regulator after going through the tests that someone (forgot his name) posted on here. Indications said it was the voltage regulator. When I first put it on it registered minus with the lights on and not running. Running it went to +5 or so and started coming down. I then read that you are supposed to polarize the generator. I did this and then nothing showed up on the gauge. I called the person I bought it from and said I was sending it back because it did not work. He asked me if I had a 3 brush generator, and I said I did. He informed with that you cannot use a generator (you can but you don't hook up a few things) you need a cut-off. I got one and did polarize it before starting.
Forgot to mention that it originally had a 4 position light switch. I tried lights and amps went to minus -9. Started tractor and amps jumped up to +20, put volt meter on battery and was charging at around 8+ volts.
My question is, why are the amps too high and what could be causing all the amp draw. No lights on, just generator brushes and starter brushes slightly dragging on rotors.
Sorry for such a long post but wanted to explain problem. I put the lights on, two head lights and rear light. They work fine when not running and running on both D and H.
Thanks in advance.
