My Bally Mr. & Mrs. Pac-Man kicks the ball to the left from the upper left saucer with such force--without the glass on top it will launch it out of the game about a foot and a half. With the glass in place, the ball hits so hard--I swear it will break it one of these times--shattering it into a million pieces before my eyes.

It would appear to me that the solenoid for the top saucer (Upper left -- kicks both ways) is wound to tight or something. I don't know how to adjust solenoids but this one could use the volume turned down from 11 so it doesn't scare the bejesus out of the player when the ball is ejected.

Any insights or could someone point me to a thread that explains how to turn the strength of a solenoid down?

Quoted from YeOldPinPlayer:

According to the manual at IPDB it should be a Bally AN-26-1200. https://www.flippers.com/coil-resistance.html shows a resistance of 12.5 ohms for that coil.
Also check that it's mounted properly so it's kicking in the right direction.

Well if I'm reading that image correctly, it shouldn't be an AN-26-1200 but rather a AO-29-2100. My photo shows that someone replaced AO-29-2100 with the aforementioned AN-26-1200 which is for the "Outhole kicker". The outhole kicker must be for the skill shot saucer. I'd say I have the wrong solenoid in the Kick to Left "Top Left Saucer."

So I'm a little confused. If 1200 is the number of coils an you increase them to 2100... won't that make the solenoid even stronger?

Quoted from YeOldPinPlayer:

The larger the number, the more wraps of wire. The more wraps of wire, the higher the resistance, the more power 'used up' by the wire, so less power left at the kicking arm to do the work.

In that case, I need to get the right solenoid on this thing. No wonder it's kicking the glass like a mule--it's almost twice the strength it needs to be.

Ordered up the proper solenoid from Marco. It shipped out today so I should have it in by Friday. I'll update this post when I see how it works afterward.

I replaced the 1200 solenoid with the AO-29-2100 and added noticed that the spring that was put in was also a little weak. So I added a new spring as well. She's kicking out gently to the left and not whacking the glass. SO much better.
