Following a tie-back mod installation on my STTNG pinball, I received a ground row 7 white/violet message when booting up.
I have done a visual inspection of most switches on that row and couldn’t see any spots where they might be grounded. Having a bit of an issue finding switch 37 I believe it is under right gun.
Any tips on how to troubleshoot to isolate which switch might be the issue?
Thanks
John

LTG : )
I unplugged the connector on the board and the error goes away.
I was pretty sure the error is out on playfield somewhere but it’s difficult physically tracing the wire from switch to switch visually.
