Quoted from Don44:
I wound up replacing all of the switch resistors and that was not the problem. Can anybody post a pic of the lamp/switch matrix diagram for me please?
There was no reason to do this as you said all of the resistors were working. What made you replace them all?
You have said you have checked all of the lamp wires are intact so let's assume the wiring is not the issue.
First thing you need to do is get a copy of the manual. You won't be able to troubleshoot without one.
I don't have a Barb Wire manual but am going off my Tee'd Off manual.
Switch strobe 0 consists of left, right and centre coin chutes, credit button, tournament button, and front door (service button). You have indicated that at least some of these switches do not work.
Can you confirm if any others in that strobe work?
Lamp strobe 0 consists of shoot (golf) again, credit button, cardholder, and lamps in the apron. The apron lamps are SKINS in the case of Tee'd Off. I'm not sure what they would be on Barb Wire. (This is why you need a manual.)
Can you confirm if any of those lamps are working?
If none of the above switches or lamps are working, then suspect Q33 on the driver board. You indicated that you tested this - did you test it in or out of circuit? It will not test properly in circuit. Also note that System 3 use MOSFETs instead of standard transistors. They are tested differently to TIP transistors in WPC games.
I would replace Q33 as a first step and then we can troubleshoot further from there. But I suspect Q33 is the problem.
