I keep looking over John T's notes for Troubleshooting Charging Systems in the hopes of finding the blinding light I need to sink in and solve my problem. No blinding light yet; but a statement/question.
Lots of references to "grounding". Just to be certain regarding these grounding references.....
I see no "ground" wire anywhere on the electrical system. Should I? (On my old Ford tractor the gen and VR are separate and there is a "ground" wire from the gen to the base of the VR.)
As for "grounding" the gen on this cub, I have the metal shining on the gen frame and block area where the gen is mounted. I have the metal shining on the gen frame at the point where the VR mounts to the gen frame. The VR mounting area metal shines.
The mounting area of the "dash" where it bolts to the "frame" shines as well as the metal onto which it is bolted. The metal in and around the hole where the ignition switch and ammeter are mounted shines from my grinding/sanding.
To the best of my knowledge, all metal contacts where "grounding" should occur have been cleaned well to bare metal.
But, there is no wire anywhere which is grounded to the frame - other than the positive battery grounding cable. Am I missing something?
Oops, there "originally" WAS a "grounding wire" from one of the gen mounting bolts to the coil bracket mounting bolt to a bolt on the top plate of the trans housing. I've taken this wire off, put it on, taken it off, etc. and have seen no useful purpose for it - thus it is now off. Why would such a grounding wire have existed? Do I need it?
