Hi Dave,
thanks for taking the time to reply.
The control module has several plugs going into it, I only unplugged the connector that goes to the motor. Once I unplug the motor connector, I need to power cycle the fused spur and then the control panel comes back to life, the buttons operate the lights and the LED display for fan speed also works and can move between 0,1,2,3 but obv motor doesn’t move as it’s disconnected.
im guessing it is a current supply problem but don’t have a schematic to see how it works….
