Sounds like the exact problem I had with my MMr. Tried the usual things, as you have. Ultimately, CGC sent me the playfield PCB (including solenoid driver boards). I replaced it and that solved the problem. It’s worked perfectly ever since.

Had the same thing when I installed the XL display kit. The Speaker Adapter cable provided does not work correctly with some machines. I cut off the connector closest to the display (.062) to make it easier to try different combinations. The attached diagram is what worked for me (Grey from display to Grey/Yellow, Grey/Black from display to Grey, and Grey/Yellow from display to Grey/Black). You might avoid cutting the molex connector off if you can remove the pins and rearrange them.

This is what worked for me.

Great. Glad it worked out. Amazing how much better it sounds when both speakers actually work!

Makes me wonder if other people don’t realize they’re only getting sound from one speaker….

Issue is not just the LE. I have a Standard game, and after installing the XL display I was disappointed with the sound quality and within a few minutes realized only the right speaker was working. I contacted CGC and they said it was an “anomaly” affecting some games. I asked for the schematic for the adaptor cable and modified the connections per their suggestion. Don’t know how widespread the problem is, hopefully it’s rare.

This shaker problem didn’t exist prior to the last software upgrade, the one needed for the display/lighting/topper kits.

Seems like CGC broke the shaker with software, why can’t they fix it with software? Don’t they test it?

You can’t adjust the weights without drilling a new dimple in the shaft.

I also have my shaker turned off. It shook so hard during Madness Multiballs that it would set off the tilt!

Fix the software CGC.

I bought the Classic Edition in 2018, and added the shaker just after that. The shaker was always very mild. Then last year I upgraded the software when I installed the XL display. And the shaker was on steroids after that, even on the lowest setting. And it seems they tweaked the software because the shaker also activated during additional events.

Curious to know if anyone else had the same experience.

Adjusting the tilt was the first thing I did. It’s dead center and as low as it can be and still contact the ring.

You know they modified the software because prior to the upgrade the shaker wasn’t triggered by a shot through the little ball lock door. And after the upgrade is when the shaker strength went berserk. They did something….

No big deal. It’s shut off. Don’t miss it that much.

Thanks for the tip. Never noticed the Additional Shake menu item. I rushed down to the basement and turned that item off….unfortunately for me it didn’t seem to reduce the intensity of the shaking.

The shaker on my AFMrLE is perfect. On my MMr it’s like the Tasmanian Devil is inside the cabinet, hopped up on sugar, and wrestling with an alligator that owes him money!

Just too much for me.
