I recently acquired a 1942 John Deere A with a 12 volt starting system that needs re-wired. Does anyone know of or have a complete tractor wiring schematic that includes the starter and alternator circuits? Any help or knowledge would be appreciated!
A wiring schematic for a Model A, I don't have. An internet search may provide you one. If you have a 1942 tractor with an automotive style alternator and twelve volt battery, then it was converted by a previous owner. Factory would have been a generator and six volt battery. The auto industry changed from six to twelve volt in 1955. Tractor manufacturers followed.
