Ok, so I thought I had a good idea on an early Stern (Lectronamo) to set up a credit switch without messing up the cab or coin door.
I spotted a point on the coin door where I could mount a switch on the steel bracket to the right coin mech (left from the front of the coin door, right from behind it).
Got it mounted, verified switch action and jump wired to coin switch.
If I manually hit the new switch, it adds credit as expected.
I have verified that, when hitting coin reject (powered off, continuity test) that the switch does close.
Power on - coin reject does not trigger add credit.
I don't *see* any wiring connected to the reject mechanism. I HAVE to be missing something.
(and no, there is no free play option on the Alltek MPU boards per docs)....
