Looking at it as in the above picture, the left terminal should be negative/ground, the right positive.
Okay, thank you for the reply. The reflector should be turning clockwise, correct?
Clockwise is correct. If you look at the wire that goes to the light, that is where the positive connects. Both motor and light wires are soldered to that post below the bar. Just an easy reference for others.
Both do run to the motor. 1 pos, 1 neg.
Pos wire goes under rotating assy to bulb.
Very simple wiring design.
