I acquired the afore mentioned game and on a frequency of 12/15 games played, the score board goes nuts and starts rolling up and over and over the score reels. This happens after the ball drains and before the next ball emerges for play. I have disassembled and cleaned the score reels and believe I have the switches properly adjusted (Note:This is my first machine and first time problem solving a pinball problem.) When I turn the machine off and then back on, the score reels stop but the score motor keeps running. Turn it off and wait a while, I hear a relay or something inside the underside of the playing field "click" and the game is good to go again for about a dozen games. I don't know if it is relevant, but the relay on the coin door at times buzzes/hums excessively.
The game is set in "free ball" mode but there is never a free ball even when the sore/card on machine indicates it should occur. The same goes for when the special light come on and you are to get a free ball. You do get the 5000 point, just no ball credit.
Any help would be greatly appreciate and acknowledged!
