Only use the NO for red wire then usually blue for ground bottom crimp connector usually

I tried this and it did not work. When I flipped the lever on the switch, the monitor picture "bounced" but a game did not start.
njay:
can you run the wires to a single microswitch a new one and click it

I really appreciate the help but I'm not sure why you're requesting that I get another switch- I tested the one I have with a DMM before using it and the lever was opening and closing the circuit like it should. Do you still think there's a chance of it being faulty even with that?
vintagegamer:
So it looks like it may be a problem on the board of the game :( With the help of another game geek we tried jumpering the wires for the coin switch at the edge connector and nothing happened.
Guess I'll need to learn PCB repair :(

That sucks vintagegamer. I just found your thread on KLOV (I think, just closed the window) Noticed you said the PCB was covered in black dust. If you're gonna be attempting to repair the pcb, best place to start is to clean it up with some compressed air, isopropyl alcohol, and q-tips. Go slowly, get everything clean, and examine the board while you're doing this, front and back. You're looking for any broken traces, any areas where it looks burnt, cold solder joints, roms that have popped partially out of socket, any legs on the chips that are bent up.
Are any of the chips on the board socketed? If so, take them out (gently) and clean the inside and outside of the legs with isopropyl or gently scrape them with a screwdriver for the tough dirt, then put them back in (again, gently, make sure the legs are all going in, and make sure the chip is in the socket the correct way).
I would test at that point, then go on to trace the coin up circuit on the board. From a brief look at the schematic in the owner's manual ( http://www.tamdb.net/index.php?page=ManualDetail&id=3047 ) it looks like the coin and test circuit is on page 26.
You may get lucky and find that it's something simple.
