How should this coin door switch be wired up for my Williams Comet? I have 2 white wires and a black & red wire.
On the switch there's COM/ NC/ & NO options.
mine is just soldered to the two available connections.(of course it always starts in bookkeeping mode!) if you have it licked, let me know how!!! lol
Quoted from jrolson:
Got it figured out... Black is power which goes to COM.
Whites both connect to NO.
Wrong (although in reality doesn't really matter)
Look at page 21 of your schematics
The Black/Red wire is the memory protect signal back to the MPU...That goes on the NO
The white wires are grounds....They go on the COM
If you want to be accurate, that is
