In the following video I demonstrate the freak tilting I'm getting on my BPM. It happens when the ball rolls down the right inner lane. Most other things are working correctly. I've got a few lamps out but that's the next thing to tackle.

If you have any ideas what I should look for on this issue please let me know.

Thanks

Thanks cat boxer. I have a second lamp board that I'm going to have to go over and try to bullet proof it. I'll try the diode on the switch. I've also read that grounds can cause lamp driver transistors to blow. Thanks again

Thanks. I will do my work with the power off.
