Yep, like Mr. Cooke said, until we get more info, no way can we determine what your root cause problem is. I suspected you had a 12-volt conversion; many non-starting issues are related to poorly done conversions. Just slapping a 12-volt battery in the tractor isn't the answer nor one of the correct ways. Do you have an alternator too or still a 6-volt generator? I'd start by first downloading a copy of the WIRING PICTOGRAMS by JMOR from our HOW-TO's forum, subcategory ELECTRICAL. Here is the LINK at the bottom for quick access now. Next, find your model in the list and verify EVERYTHING is good to the schematic. Get the battery checked, charged if needed, or replaced if needed. My hunches also lead me to believe you have some jazzed-up wiring issues going on as well. This is how I would proceed, so once you do these checks, report back. If nothing else, the post gets archived and can be accessed by future users with similar problems.
