I have a reverse engineered diagram for a Walker Mark III golf buggy by Parmaker Products P/L. All it consists of is a CA3524 PWM controller driving a DC motor unidirectionally via two parallel-connected MOSFETs. I can scan it if you are interested.

Any chance that you have a regenerative braking circuit for any electric-powered vehicle? I would like to look at something known to work; I will need to make a switch-mode regenerative controller this spring to provide braking and battery recharging by a step-up conversion from the motor back-emf (about 30V at high rpm up to about 40V for charging).

Make sure you engineer it so that the wiper of the pot breaks contact easily , and control goes to maximum rather than minimum, in that fault circumstance. Causes much hilarity on the golf course.
