Not really playing, but I grabbed this nice Jacks Open last month. Gentleman I bought it from said that it stopped working as soon as his buddy changed it from 5-ball play to 3-ball play. Boy... If only it were that simple. Game was dead as a door nail when bought. No lights, no start, nothing. I broke my own rule, and tore my hair out cleaning connectors, instead of starting simple and buzzing out fuses and solenoids first...
Actual cause of problem was the pop bumper solenoid switch was shorted shut, and that damn pop bumper was roasted so badly, I'm surprised it didn't catch fire. There had to have been smoke at the very least. Took me 5 minutes to track down the short in the relay under the playfield. Swallowed by pride, and that'll be the last time I break my rule of checking fuses and solenoids first.
Anyway, played a few test games to make sure it all worked well, and now with this horrible weather, I have an excuse to exile myself to the basement to tear it down the playfield and rebuild it with fresh parts.
