Hi, wondering if maybe someone could point me in the right direction. Troubleshooting a very clean, and working perfectly (other than this one issue) Gottlieb Pioneer. I've cleaned contacts on score motor and ball count unit in back box. If I manually trigger the ball count, it steps through ball number and switches between player 1 and player 2 on the front display. Power on the game, add a credit or two (this happens whether one player or two), launch ball and play/score. Ball drains, kicks back out fine, still shows as ball 1 on display. (never ending game)

I'm just not 100% sure where to target/pinpoint which particular relay or set of switches that may be causing this.

Thanks in advance,

Tim

Didn't watch for that, but will check this next. I found one post with similar or almost same symptom, and there was some mention of AX relay/switch as well?

Thanks again for your help, went back to look at this machine further, cleaned the contacts on this one switch and now the game plays flawlessly!
