System 11c coin door 3-switch wiring

[cooldan]

Hi all.

‘Adjustment Failure’ on Rollergames
New batteries, no leakage, 5V at RAM pin 24.

It’s the switches inside the coin door, the “game adjustment/Diagnostic switches’ part 27-1008. One wire is detached, plus I removed the coin mech and credit counters so I also have a couple of other loose wires.

I’ve been looking online but cannot find what I really need, a colour photo of what wire goes where on those switches. A schematic maybe, but I’m not much good at reading those things yet.

Can anyone with a Sys 11c game (see pic) take a few photos for me please?

No rush, enjoy Christmas Day, but any photos would be much appreciated and maybe I’ll ask you to post me some gubbins later!

Here you go

ok, so it appears you have TWO green-with-a-hint-of-brown wires, where do they go please Paul?


on mine, one of these is hanging loose, i think from when i ripped out the coin and credit thingies. can i just ignore it?

This is mine now:

Green and brown appear to be common across all switches. Comes into loom and loops to all 3 coin drop switches.

The only other green wire is green only and that is just a single wire tk the connector.

Sorry for the delay. There was a turkey that needed eating.

Green brown also loops to slam tilt.

Two of the buttons (that are the up/down and advance buttons) run direcely back to the MPU board on its own connector. Sometimes on the door is a memory protect switch that also runs to this connector.


The other switch loops off to coins/slam tilt etc. I believe it is reset high scores (but I could be wrong). Nothing loops from the left single switch to the right two switches.
