Bought a Sabvoton SVMC72150 and installed it in my bike with a 60v battery and QS hub motor. Powers on, works great, motor spins the wrong way. Go into the settings on the UKC1 display, power cycle the controller, motor still spins the wrong way. Ok, weird. Unplug the UKC1 and plug in the power jumper and use the phone app with the bluetooth dongle. I get an error that is never mentioned in their documentation that says "restart" no matter what I do. Won't let me do a hall test either. No settings I change will save to the controller. Grabbed their USB cable and tried the program on my laptop and it also didn't appear to be communicating with the controller properly.
This model controller does not have a jumper to reverse rotation.

As far as my wiring goes, the motor, throttle, keyswitch, and brake switch are hooked up. The UKC 1 is disconnected in this picture.

Any ideas appreciated.
