Thanks dean.
I thought it should have some kind of background noise.
As for the pothole kicker i have not had time to dig around but as it only activates and stays latched after it fired was worries it's a board fault? Hopefully get some time tomorrow to nut it out.
Also another question the roulette wheel motor doesn't spin it hums when activated but won't spin. The gear box isn't seized is there anneasy way to test a motor without removing the whole assembly?
