Hi,
I am wrapping up a baby PACman electronics restore. My last known problem is the left flipper. I have replaced the coil due to the plastic seat of the solenoid being separated from the coil. Looking at the schematic it appears there is a cap on the switch mounted directly beside the coil. The right flipper has either a diode or a cap across the break switch. I am assuming that the left should have a similar setup?

I have battled the vidiot, the mpu battery acid and poor repairs and am down to this issue. The rest will be cosmetic from here. Any help appreciated.

I happen to have a Baby Pac playfield here and I checked it.... it looks like a Zenier diode and not a cap. On my playfield, it's only on the right EOS switch and not on the left.
 
Bally left flipper

Hi,
Thanks for looking and your reply. I havt the diode on right and none on left. When I move the flipper to the engaged position it locks after the eps switch makes. It will not engage on it's own.

Going to start checking wires. This solenoids wires were extended like they had been worked on before. Just like the other repairs it was a mess.
Thanks for your help.

Baby is dine

Hi,
Found the end of stroke was not fully making contact. I have learned slot about flippers and Bally vidiot and mpu boards. I mostly worked on Williams stuff before. I think the Bally system is a bit easier than Williams.

I have to start on the cosmetic stuff now.

Thanks for your help.

Glad to be of help. I have a Baby Pac that's on my list to be restored as well as an extra fully-populated playfield.

Do you know of a source for the CPO and the side art by chance?

I haven't looked at my baby pac in awhile but I think you're referring to the diode on the "ball launch" switch (which is part of the switch matrix). There are 2 switches on the right flipper, the end of stroke (EOS) and the ball launch switch. When you press either top or side right flipper button, the flipper coil is activated and upon reaching full stroke it opens the EOS switch and closes the ball launch switch thus kicking the ball into play.

The left flipper should only have an EOS switch and no diode across it.
