Hello,

I recently had a reset on my Getaway with the playfield tilted up to change a bulb and afterwards I get a Shifter Error. The shifter does not work at all

I found a wire loose on the J206 connector and subsequently repinned the entire connector. I also ended up rebuilding the shifter microswitch area with new switches, diodes, wires, etc because of some previous owners shoddy work and a poor feeling switch. The error didn't go away. The shifter switches do not activate during the switch edge test. It turns out, everything on column 3 on the switch matrix are not working as well (green/orange wire). In the switch edge test screen, the matrix looks like it should on a working Getaway

I went through and checked the continuity of the wires on all the green/orange, white/yellow and white/orange wires in the playfield and down to the shifter and nothing is shorted to ground. I also checked the function of the switched on column 3 with a DMM by operating them by hand.

I also looked at the CPU board to see if any of the ICs looked burnt and nothing is obvious.

What I think I am down to is:

1. diodes are backwards on the microswitches (I am pretty sure they are correct)
2. bad chipset on the CPU board

What are people's opinions? Also does anyone have a good picture of the shifter microswitch wiring so I can crosscheck my work?

Easy to compare diodes to every switch in your game. Silver band end of diode and white wire there, green wire there, black end of diode there.

Other than stripes on the wires, base color and diode orientation is the same on every switch.

Unplug the shifter connector from the bottom of CPU, if error remains you know you hurt the CPU. Switch IC's like U20 and LM339's don't show burn unless you get really creative.

Oh yeah, good point on looking at other switches for reference.

Update: I've now getting Opto errors too. Looks like the mainboard needs some RnR.

Getting a shifter error now. Doesn't recognize in tests so must be a connection issue. Where is the connector at the bottom.of the cpu you are talking about? Does anyone know ?

Going to open it up in a minute and start checking the connections.

Thanks yall
