I'm' new to owning my own machine and have run into a few issues with the afore mentioned machine. Picked it up as a fully working machine for $500. It did launch balls and score but, fully functional was a bit of a stretch. Buy a forty five year old electro mechanical device for $500 and you can expect to operate as such I guess.

The machine is set in extra ball mode and does not score one when proper tally's show on counter board. Once I heard the "knock" sound like is given for a extra credit game, but failed to look to see if a n extra ball was credited.

More importantly, about every 15 game plays or so, the machine freezes. If you gently rock one of the cams on the scoring motor, the unit resets and all is well again. In addition, occasionally the score board starts running on it's own and keeps going and turning over without stopping. While this is gong on the scoring motor and the cam shafts keep spinning. If I shut the machine off and turn it back on it starts spinning again. Sometimes the score board stops and the scoring motor continues.

If I remove the glass and open the unit/prop the playing field up, and then turn the machine on, the

problem goes away and game function well again.

I am new to internal workings of these devices but, but was a shop teacher 37 years. I am fairly mechanically inclined. I also have the machines wiring diagram and slowly finding my way around.

I would appreciate any incites of what and where to check. I would like this old machine to stand tall again for another 45 years.

Best Regards,
