Thanks for your help, guys.
Another day in the garden, but will no doubt be back and forth to the pinball machine.
I checked the bonus unit and all wires seemed to be attached securely and if I move the wheel by hand, the bonus lights cycle on the playfield. If I start a game, the Bonus Unit will reset back to zero ok.
I have noticed that when the start button is pressed, the machine resets score reels and the bonus unit and before everything stops, the Coin Relay releases and then finally the Reset Relay.
Cheers!
Adam.
