The switch problem might be tilting the game. Does the tilt light come on?

The capacitors on the switches do fail and cause a stuck closed symptom. If the switch is open but the test mode is showing it closed cut one end of the capacitor loose and see if it clears. There is usually a capacitor near the plumb bob tilt or roll ball tilt in the cabinet.

A limitation of the switch test is that it will only show the lowest switch number that is closed. So if a switch matrix problem is making the CPU read switches 2,10,18,26,34 as closed switch test will only tell you 2 is closed because it is the lowest switch number.

Quoted from Pin_Bob:

First of all I want to thank everyone who replied here. I am fairly new to pinside and what a great group of people with willingness to help. BarakandI, I failed to remember that when troubleshooting any problem always look at the obvious first. Yes, the tilt plumb bob was off the hook and shorting out causing the game to freeze. I had the backglass off so I never saw the tilt light come on. My bad.......
On the switch error, I clipped the cap off and now the error is gone and the switch works fine. Should I replace that cap or just leave it off? The game seems to now play fine.

It will work without the cap but switch may not register/score fast quick hits. If you think it's playing fine without you can leave it off.
