My old Case 446 doesn't charge the battery. I've been putting off fixing it for the last month or so, since I have some spare time now I decided to take a look at it.
After looking things over I have decided that the Regulator is not working... I have approx 30 Volts AC out of the 2 wires going to the Rectifier and 12 Volts back to the Red wire from the Ignition switch when the key is on. I put a ground directly from the regulator mounting screw to the battery negative post.
I suspect that the 83 Case uses a half wave regulator as only one wire from the Stator goes to it and the other Stator wire is looped over to the Red charging wire. This is an Onan B43 on a 1983 Tractor.
I was wondering if anyone has used the more conventional rectifiers that are found on most other gt's the type that have the Stator hooked to the outside 2 terminals and the odd terminal goes to the battery?
I'm comfortable with the wiring and the savings would be quite a bit as Case Ingersoll evidently was one of the few to use this system.
