Just firing up a Pinbot after it was stored for some time. This is what is happens upon startup. The left upper kicker keeps firing. What should I look for?

Not the switch, as I disconnected one side of it and the kicker still fires.

Would you know what connector position that is? Sorry, EM guy here.

Got it. Checking it now.

OK, so with both unplugged at the same time or either one individually, the kicker does NOT kick. With both J8 & J10 plugged in, it constantly keeps kicking.

OK, I ran the diagnostic test and came back with no errors. I ran the complete series of tests as well as the Auto-Burn In. I also unplugged J8 and J10, and placed a jumper across J10-9 & J8-4 and the display showed the left eject position. So I can rule out the CPU I guess.

By looking at the Switch Matrix Table, the J10 Wht/Br is common to 5 other switches. The J8 Grn/Yel is common to 7 switches.

Would one of these switches or diodes affect the left eject kicker?

The circled switches are not working. So with wiring continuity, are the switches wired in series as shown in each row and column?
