I have rewired my '51 H in accordance with Bob M's wiring diagram. I have a 6 volt positive ground system with a brand new 6V regulator. The genny is off of an early '50's Chevy. It is a 6V unit and has been checked out by a local genny shop and declared OK. I have a 3-position O-D-B light switch.
Here's my problem. When the tractor is running, I get no indication on the ammeter that the charging circuit is functioning.
I asked a local mechanic to backcheck my work and see if he could get the charging circuit to engage. After verifying that all was wired correctly, he installed a jumper wire from Terminal 3 on the back of the light switch to the GEN terminal on the VR. With the engine running, he then switched the lights on, and then immediately back off, and the ammeter instantly showed current. He said I should leave it wired that way and just run it. That solution does not seem correct, because when I run it the lights stay on even though they are switched off.
Can someone help me resolve this problem so that the charging circuit works without the jumper wire/lights on condition?
