Quoted from Aniraf:I’ve run a switch test, which doesn’t show anything out of the ordinary and coil tests that work perfectly.
So when you run the switch test and operate all the switches by hand they all work including the coin mech switch?
Yes. Check the Green/Brown wire, that's your column wire, and whichever coin mech(s) are not working (white wire with a stripe as shown on the left of the switch matrix diagram) They could be broken where stressed at the coin door, or possibly broken at whatever switch they are daisy chaining from. The switch itself could be bad, so momentarily grounding the column to row switch should register a coin if the wiring is good, so you might check that first.
