Here is the update . It turns out the previous owner press fit a plug with a threaded end in the belt pulley attachment. It looked like a stud for the ground, but it wasn't. My connected ground to this wasn't good enough. Also there seems to be a short in the lighting system. I took the tractor down to only wiring the charging and ignition system. The system starts and charges fine.When I connect the lighting system wires get hot and it blows fuses ( someone put 30 amp fuses in this tractor) NOT GOOD. The wiring on this is a real bad job by the previous owner all homemade with lots of splices, not even close to original setup.

( I hate it when people dont have wire long enough so they use 2 ring terminals and a bolt then hide it under electrical tape and plastic conduit).Seen this more than once.

I have a new harness but sending it in for paint first. Just wanted to make sure the system works .

Thanks Jim for the insight into the problem.

Your short when the lights are connected could be a bad "fiber board" which acts as a small terminal strip where the lights are split from the switch supply. The fiber board on my W4 crumbled when i touched it. Located at the front of the tractor just under where the hood and grill seem is...one wire comes up from the switch and two wires go out to the headlights. Just replaced it with some masonite i cut from scrap.

Um, that plug is a dowel and is suppose to be there. It would explain the bad ground too.
