What's a multimeter?
KIDDING!!!!!!!!!!!! I'm going to check it out and order the diodes on Amazon.
-edit-
I do see they're grouped in pairs. Referencing the picture above, the top two would be negative and the bottom two would be positive. That clears that up.
Just an update and a big question and concern. I wired up the controller to the motor and then to a temporary 24v battery pack (two little 12v batteries, 3amp each) just to test it to see if the throttle works and to mark the positive and negative of the motor. I can get the controller lit up, but with the throttle I can't get any action from the motor. Controller is lit, batteries are hooked up, but nothing from the motor.
I have B+ from the controller going to the + on the battery and + on the motor
I have B- on controller going to the negative of the battery pack.
I have a cable going from M- on the controller going to - on the motor.
