My meteor is tilting when the spinner is hit, it has an alltek MPU. Can anyone please lend some help so I can knock this problem out. Thank you guys

Go into switch test and report any issues. I am guessing a bad diode on a switch in the matrix.

First, remove ball and verify switch test shows no stuck switches with all drop targets up. Second, when it happens, quickly shut off the machine and post a pic here showing which drop targets are down.

Ok, did a switch test , all is good

Next I tested all of the drops one by one and located the second “E” to be the culprit in the Meteor drops... what do I do next?

Am I just looking at a bad diode possibly?

Yup, probably a shorted diode on that switch.
Just to confirm, all targets up except for 2nd "E" target, spin the spinner.....everything should be normal.
Drop the 1st "E" target, spin the spinner......game should tilt. That would point to a shorted diode on the 2nd "E" switch.
