First, your old/original generator just needed to be rebuilt, you didn't need to buy one of the newer aftermarket ones sold today and as you found out why, -fit issues. The trick is to find a decent shop where they know about Ford generators and have the specs they are to be set to. They can also bench test your genny, ammeter, cutout, battery, coil, and more. Do you have the 1-wire/3-brush generator? There should be a 3rd Brush Adjustment screw on the back end plate. Turn it CCW all the way for now. If it is the correct generator, there should be a tensioning bracket attached to the barrel with another piece/positive stop fastened on the head. You need to keep proper belt tension. Next, generators produce AMPS so that is what needs to be checked. The 2N-10000- generator produces 11.5 AMPS. The round-can cutout cut-in voltage is 8-volts +/- .5 volts. Also, if you are using a digital Multi-Meter, you will get flakey readings as static electricity interferes with the signal. You need an analog meter to check while tractor is running. How did you 'polarize' the cutout/gen? Start over, by first disconnecting the battery so no accidental shorts to ground are made. Disconnect any auxiliary items like headlights to eliminate them from the equation. Verify components are good. How old is the battery? Will it sustain a charge under load? Your starter shop can test it. The generator can be tested by him as well or you can do a simple motoring test. If components all check good, the next step is to verify the WIRING is correct. Here is a LINK to JMOR's Wiring Pictograms to download and then scroll to your setup. Do not go by wire colors, you may not have the original color-coded wiring anyway, so do a continuity check on each wire, power off. Go over all the basics, again, then if all checks out, reconnect the battery but leave the lights disconnected, at least for now, and try to run it again. Hope this helps with your non-charging issues.
