How do you test electric motor in club car golf car?

Answer 1

First, observe good shop safety procedures, including but not limited to eye protection, no loose hair, gloves or clothing, etc.

Raise the rear wheels off the ground, chock the front wheels, and hook up a known good 12v battery. The motor should spin, but not as violently as it might with the full battery pack.

Many (all?) Club Cars have a series-wound electric motor, which means that the current flows through the armature wiring (terminals often labelled A1 and A2) then through the field wiring (terminals often labelled S1 and S2). If the terminals aren't labelled, the A terminals are usually nearest the shaft, spaced radially, and the S terminals are along the side of the motor in a straight line. The motor is placed in reverse by switching the polarity of the field.

So the test battery should be hooked up so that one terminal goes to A1, then A2 connects to S1, then S2 connects to the other battery terminal.
