Okay, that clears that up. The black wire doesn't connect to any of micro-switch's terminals, it just uses one of its mounting screws as a junction point.

What had me concerned is the black wire connects to B- and the red wires on the microswitches connect to B+.

Apparently the high-pitched sound is coming from the beeper. Why, I don't know.

Disconnecting the black wire disables the beeper, but the orange wire is what tells the controller to go into half-speed mode when cart is in reverse.

I believe the high-pitched noise problem is a separate issue from the cart not running. Get the cart running first.

BTW: That is MS-4 in the picture. All it does is turn the beeper on when F/R is in reverse and but B+ on the orange wire to tell the controller to limit the motor to at half speed. Cart will run without it connected.

What voltage do you measure across the motor?
Connect your voltmeter's negative test lead to the A1 stud on motor.
Connect the positive test lead to either the S1 or S2 lead, whichever reads the highest voltage when pedal is pushed.
If you get something close to the battery pack voltage and the motor isn't spinning, the motor is sick.
