Ok, I"ve used John T"s diagnosis and it my H passed all the tests, but still wouldn"t generate DC. Replaced all wires (one at a time!) took apart generator and put back together. Ammeter definately works, I went thru his whole checklist. Motor test on GEN worked too...went back over it and I missed step 6...

I shut it off, and restarted and as long as that grounded wire is on the F term it generates fine. What"s wrong? I"ve replaced almost everything on this tractor once already and I"d rather replace/repair the right faulty part.
BTW, GEN was professionally rebuilt 1.5 years ago, battery is 3 months old, and regulator is about 2 years old.
It"s a 6volt positive ground system without Cutout relay, (4 term regulator (BAT, GEN, F, L)
Can I just leave the F term grounded? Something is telling me no.
