Can you put a volt meter somewhere on the motor leads, or measure
the
battery current or voltage drop under load?

It's a PWM controller, Jim. My DVM does a pretty bad job of showing
the
average voltage of a square wave.


I know. It's easier when you have another known-good machine in the
shop to compare the reading to. Flat-out acceleration should briefly
show full DC voltage, though.
