Wilderness Energy still in business?

I have one of their `36 volt motors in a trike and it stopped working. I've tried to contact WE and get no response. Even a circuit diagram would be helpful to diagnose the problem. I get continuity readings at the motor so I think it's OK but since they have 3 wires going into the motor I don't want to try to circumvent their controller setup and cause some damage. I'd be happy to have just an on off switch and no circuit board in between. Mike fortunare [at] gmail.com
