1949 H Wiring

Allan from PA · Jul 19, 2010

Brought home the H a couple weeks ago. Got to looking it over and got it started after it sitting more than 20 years. It had been the donor tractor for the neighbors over all those years and parts on it are not quite right. My question is can I wire up a VR as if it was a generator cut out ignoring the F and L terminals and wiring the tractor otherwise as per the manual? Still 6v with magneto and lights. Thanks, Allan.

Here is a wiring diagram using the newer 3 position light switch and a voltage regulator.

Disregard the coil and distriburtor.

Yes, if the VR is grounded, the Bat and GEN terminals act just like a cutout (they are a cutout).
A 30 amp diode will also work if connected to the bat wire on one lead, and the Gen wire on the other (eliminates massive stuff) Put it on so it does not conduct with the engine off. A test light does not light when put in series with it and ground. This allows the gen to charge, but the bat isolates from the gen when off. Jim

Thank you for your replies. I will put it together and see if I can get it to work when I get a chance soon. Good knowing the right direction. Thanks again, Allan.
