Hi All,
Great news - after the amazing posts from folks on here we determined the Farmall M is, in fact, set up as a 6v system.
Now the fun part.
I need to redo all the wiring anyway and am not sure if the generator or voltage regulator work as they are wired goofy -> goofy wire description below...
Question is, I do not know if generator or voltage regulator are good - can anyone provide details on a quick way to check both (remember, tractor doesn't run)?
Also, who knows if the switch resistor is any good, or the starter - any simple way to check?
What about the ammeter? Simple way to check?
Lastly, I can get coil, plugs, distributor etc cheaply so not worried there, but if switch to 12v system need to change out the generator and starter, no?
So, question is, is it cheaper to convert to a 12v system or keep and fix as a 6v system?
Certainly checking components will aid in this question/answer, so if anyone knows how I can cross off things to check, please let me know.
Goofy wiring:
Ammeter is connected to voltage regulator battery terminal - correct
Voltage regulator generator terminal is connected to arm terminal on generator - correct
Voltage regulator f terminal is connected back to switch resistor - what the heck
Field terminal on generator is grounded to case - what the H*
