I normally work on Farmall's but have taken on a project for the wife's uncle to get his D-14 running. I'm having to go completely through the engine, clutch, water pump, brakes, etc. Somebody in the past has totally screwed up the wiring. I know it used to be a positive ground using a generator but it has been converted over to a 12 Volt negative ground using a 3 wire alternator. Does anybody have a wiring diagram for a 3 wire alternator setup? At present it does not have a key switch, but three switches to get it to run. Totally screwed up. Any help is appreciated.
