JD 40 - 12 Volt system

[Johnny G]

John T thanks for answering my earlier post however, I forgot to tell you my dad wired it for a 12 volt system about 25 years ago. I need a 12 wiring diagram not a 6 volt. Thanks

Diagrams the same, just use a full true 12 volt (some call internally ballasted) coil and a 12 volt Generator and Voltage Regulator (unless you convert to an alternator) and 12 volt lights etc.

Thanks! I appreciate your quick answer. John T

The positive post on the coil has current running through it until I hook the wire that goes to the distributor and the test light goes out. I have an alternator on the tractor and it is a negative ground. I have a ballist resitor hoked up in between the coil. I know it is something simple.Thanks for a reply.
