Im not sure Im smart enough to fix this one over the net. Bob M and I have cussed n discussed another NEW VR he bought that isnt working quite right either.
Scotty is right on the 4 terminals on the VR but its my guess where you typed A on VR to ammeter did you really mean BAT ??????????
CORRECT WE GOT THAT STRAIGHTNED OUT
If she was charging before and charges if you ground the gennys FLD post THAT TELLS ME THE GENNY ITSELF IS OKAY so it must be a VR or other wiring problem AGREED
Are the 3 terminals on top side by side on the VR labeled BAT (L)OAD and FLD ?????????? DIFFERENT ORDER, BUT YES
If so I still think the unmarked terminal on bottom is ARM/GEN and YES it wires to the gennys ARM post. THATS THE WAY I HAVE IT NOW AND THE WAY ITS ALWAYS BEEN
MAKE SURE THE VR"S METAL FRAME HAS A GOOD GROUND maybe run a grounding jumper wire to it as she cant work right UNLESS THE VR IS WELL GROUNDED RAN A GROUND LINE AND CHECKED CONTINUITY AS WELL
YES that wirewound stick resistor on VR is the series Field resistor, it sort of takes the place of the resistor on a LHBD light switch. THOUGHT SO
With the VR theres NO LONGER any wire from FLD on Genny up to the light switch remember, you dont have such a wire correct??? CORRECT, NO WIRE TO SWITCH UP FRONT
I guess you surely Polarized the genny prior to start up right?? if a genny is at the wrong polarity it can damage a VR !!!!!! DID THAT
On the ammeter the SUPPLY SIDE has but one wire to the battery often via a cable to where the big battery cable attaches to the starter switch. Its other LOAD SIDE wires to BAT on the VR... Yours that way??? YES
You may not wanna hear this but if shes wired right???????? AND POLARIZED and charges ONLY with gennys FLD grounded THE VR SOUNDS BAD !!!!!!!! or the wires bad from FLD to VR FLD or the VR isnt well grounded VR RELAYS "MOVE RIGHT" WHEN ENGINE IS RUNNING, VR IS GROUNDED GOOD, GOOD WIRES EVERYWHERE
I hope Bob or Bob M or Jim can fix it, Im runnin outa smarts and I dont have all that many to begin with.......
YA, AT THIS POINT I DONT KNOW TO WIND MY A$$ OR SCRATCH MY WATCH, THANKS FOR ALL YOUR HELP JOHN!

Today's Featured Article - Uncle Cecil's Super A Lives Again - by Mike Purcell. A week or so out of most of my childhood summers was often spent with my Uncle Cecil and Aunt Sissie in the small East Texas town of Maydelle on their 80 acre farm. Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecil’s 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea
