I cannot get the override to work.
You need to count the flashes of the red and green lights.
The green light is for the motors. One flash is for motor 1 and Two flashes is for motor 2.
Once you've counted the green flashes (Sounds like it may be motor 2), count the red flashes.
The red light is for the error code.
2 flashes = Battery dropout
3 flashes = Low battery
4 flashes = High battery
5 flashes = Excessive motor current
6 flashes = Motor short circuit
8 flashes = Hall Effect signal not present
9 flashes = Hall effect power short to ground
Once you've counted the flashes come back and let us know what they are and maybe we can help figure out how to fix it.
I'm a little concerned by the voltage from the switch fluctuating at the controller. Do you have a volt meter that you could hook up and take some readings over a few seconds? If so, take a voltage reading at a convenient place and see what it is. Then press the button and watch the voltage. See if it drops and then spikes up pretty high. report what you find.
