If you have an alternator an you hook it positive ground you can kiss that alternator good-by.

The tractor will work with either setup just change the alternator to a generator and swap the wires on the Amp gage to match the battery setup and then polarize the Regulator.

OH! its funny the serial # that you gave is for a 1944 case it must have been sold to the government in 45 to be marked that way.

i for got when its hook neg to ground right now i've got no spark when its pos to ground i have spark.

If you tractor contains an oil filter it will be in a canaster on the right side. It may have not been equipped with one. If you have your battery hooked up neg ground for the alternator, I assume it is 12 volt. You may have the wires reversed on the coil. Check that as well.

Ree;

The tractor was originally built with negative ground, not positive like the Ford's positive ground system. Most common alternators used as a replacement are also negative ground... Gene
