Hoping one of you experts can help me. I stripped all wiring (a real mess)and am rewiring. I"ve downloaded several diagrams from various sources and remain a little confused as to what I"m dealing with. I have a 12V battery so I"m assuming it"s been "converted" from a 6V system. Negative ground I think. I believe it still uses the three wire generator, not an alternator, but I"m not sure that"s possible?? There was no resistor coming from the coil so I"m guessing the coil is 12V. I"m understanding that there"s no "standard plan" but I"m hoping if you see the pictures I"m posting you can give me some tips or guide me to a diagram that will work. I drove this tractor home a couple years ago when I bought it and actually put it to work a few times before I ran into troubles with engine, etc., and decided to rip into it. Attaching a few pictures of what I was working with. The charging system seemed to be OK so I know the cobbled mess of wiring somehow worked! I have a few diagrams and I'm posting the one I think is closest EXCEPT I don't see the wire from the coil... Never been really great with wiring so starting to get frustrated. Want to make her run after a complete engine rebuild before I put the sheet metal back on!
