Attempting to set up add credit from coin eject - early Stern...

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.

Any ideas?

(and no, there is no free play option on the Alltek MPU boards per docs)....

Yes, good idea - I didn't think of that. I'll try it.

Yes, I'm going to do it shortly. I think I'm going to try heat shrink tubing and cut out a small section for the contact.

BOOM baby.

That was exactly it northvibe !

Thank you for spotting it!

I have a bunch of heat shrink tubing ready to use so I figured it would be more durable than electrical tape, thank you for the suggestion slochar !!!

I was having a hard time with it in that position, the arm/whateveritis from the coin eject wouldn't hit it right, or maybe it was that it was possibly in the way of something else.... oh wait I know what it was - the stiffening arm was preventing that side of the switch from actuating, that and there was too much of the stack in the way that kept the switch from actuating properly.

Didn't feel like tearing the switch stack apart to trim that down.

I should have searched for other posts on this - I didn't know it was documented!

Yes that looks like a good option too. I don't mind drilling in the coin mech bracket. I know it won't move after I mount it.
