Ok, so the magnet looks ok as does the pickup. I tested the pickup according to Inwo posted (not sure that was for me, but I did anyway) and get no readings red/black green/black when I rotate the motor (power & key on)…does that indicate a bad pickup? I see no issues with wiring.

Yup, My guess would be the pickup/sensor. You can find them on Amzon.  
Like this one. Does it look like yours? $18 on the lower end.

But - odd that you got no readings? Not even between the red and black coming from the harness? Or are you measuring the sensor wires itself?

I was measuring coming from the motor. That does look like the correct sensor. Thanks.

Voltage comes from controller. Sensor must be plugged in to test it.
