Hi there. The End stop switches seem to operate correctly the 2 leds for both end stops are off. The diodes check out ok, the motor checks out ok. The unit has also been bench tested and is ok. The sensor in the steering column shows a voltage variation of around 2 volts either way sitting at around 2 volts moving down near to zero and up towards 4 v. Any other pointers?? Clutching at straws, not sure what else to check.
