John T, I've crawled all over your diagnosis posts, I assume I do not have a "cut out" system considering the novel I have written below.
Long story, completly restored, good strong batt, new harness, new "4 terminal" VR, gen puts out. It was doing ok after I put the new vr on, it sits a while and then wont charge. If I ground the F term, it will charge. I cant find a diagram in any pub that looks like mine. The new harness was installed from the directions with the new harness that I got from this site a couple years ago. My oringinal "self drawn" diagram, from when I tore it down for the restore, shows one wire from the genny and 3 total connected to the VR, including the one from the genny, I could have missed something here. In an attempt to nail this thing down once and for all, please check my connections up front. VR came from Tractor Supply. It was working with the original VR before the tear down, then stopped after the restore, then it worked with the new VR after the restore, then stopped.
"F" term on genny goes to F term on VR
"A" term on genny goes to un-marked term on underside of VR. This term reads a dead short to the connection under the VR cover that goes to the big coil. From that connection (the big coil) to ground, it reads 12 ohms.
"A" term on VR goes to one side of the amp meter
"L" term on VR goes to one side of ignition switch
All the diagrams I can find show the resistance unit in the steering tower, not on this one, though there is a wire wound resistance "stick" on the underside of the vr, that goes between ground and the "f" term on the VR, this shows 14 ohms across the terms of the "stick" and dead short to ground, on the grounded end. I assume this "stick" is the load resistor that is documented as being in the tower in all the schematics I see?
Light switch frame on tower is well grounded.
Sorry for the long post, this has been a husk in my teeth for quite some time now.
Any comments and suggestions are welcome. and very much appreciated

Today's Featured Article - Antique Tractor Wiring Basics - by Curtis von Fange. One of the most neglected parts of old tractors is the wiring. After sitting in the elements for half a century or more much equipment wiring has deteriorated to sparsely covered strands of copper or other metal. Plastic insulation has cracked, mice have eaten through the older clothed style coverings and the exposed wires have reacted to winter moisture and salts by turning blue and powdery. Terminal ends have corroded, rusted or just plain evaporated away. Aged wires not only keep an engin
