So I'm getting ready to sell my Twilight Zone and I'm going through making sure everything is working, shopped, etc, you know the drill. Well, out of nowhere the Coin Door switches stop working.
Here's what I've done so far to troubleshoot:
- Test for continuity from switch wires to the PCB right inside the coin door. Good
- Test for continuity from the connections on the PCB to the other side of the PCB. Good
- Test for continuity from Harness on the PCB all the way to the harness in the Back Box. Good
- I CAN NOT jumper the wires to simulate the buttons from the wires from the switches.
- I CAN NOT jumper the wires to simulate the buttons from the harness that goes from the switches to the PCB.
- I CAN NOT jumper the wires to simulate the buttons from the harness that goes from the PCB to the Back box.
- I CAN jumper the contacts on the CPU board to simulate the switches and get into the menu, etc.
So.....anyone have any ideas of where I may have missed something? Any help would be very much appreciated.
