62 Valiant 200 / 170 cuin /6 - Odd smell - then dead battery

Actually now I'm not sure where the fault is.
I thought you were just bypassing the regulator. That would explain why the voltage followed rpm.

But reading this, it sounds like the field wire was jumped.
Which then resulted in the connection to the rotor being made.

If so, then the regulator should be controlling the voltage.
