You quite likely burnt a wire somewhere between the regulator and the battery. One thing I see here that everybody missed is Ford generators are backwards from everything else. Our A-C's with a Delco generator control the field on the GROUND side of the circuit. That's why when you ground the F terminal on a Delco, it gives maximum charge. Ford on the other hand chose to control the SUPPLY side. So when you grounded the Field to the chassis, you created a direct short to ground and something couldn't take it. My guess is the ignition switch or a splice in the harness. You've probably welded the points in the regulator too.

I'll take a look at it.
But like I said, I've done it before with no ill effect. I've even found it on generator testing charts; ground the field to max out generator output.
And keep in mind the switch and wiring harness are fine. I got it to run by jumpering across the resistor.

You may have a resistance somewhere else in the wiring and by shorting the resistor you compensated for that resistance. I would still check ALL wiring between the battery and the ignition switch and the resistor. Go ahead and put a new resistance in, but be prepared to check the wiring if the resistor doesn't fix the problem.

If you short the field terminal on a Ford generator or alternator to ground, you'll weld every time. If you grounded the field terminal, and didn't burn anything, you didn't have a Ford charging system.

Check the battery terminal at the regulator with a test light. I'm betting you find no voltage.

It might be 'show and tell' time ! Please post a picture of the genny/regulator and the 'ballast resistor(back of left dash are) as Brian might be onto something. This is one of those hard to 'long distance' troubleshoot problems that a picture could be worth more than 1000 words !
since I can't get my tractor into my garage I have some free time.....
