New Rad City 5 high step, got code 30 out of the box. Rad sent a new wiring harness and motor controller. Wiring Harness arrived first. I replaced it but still got code 30. New motor controller arrived yesterday and I installed it today.

Now code 30 is gone. But I only get power for about 1 or 2 seconds and the power to the motor cuts out. The display and side panel are still on, no errors reported. The headlight and taillight are still on. But no power to the motor in response to either hand throttle or PAS mode.

I had the same rough time as pjiaria finding the screw holes in the controller during mounting.

Very discouraged. I'll contact RAD CS tomorrow, see what they propose next.
