OK -- I can't see a coin counter, so we'll jsut look at the mechs. Beneath each of the mechs, there should be a microswitch with a wire attached. When the coin is dropped in, it should fall through and move the wire, momentarily activating the switch.

On each switch, there are probably three prongs -- one for ground (COM), one for normally open (NO) and one for normally closed (NC). Ignore NC.

I can't see any wires in the pictures -- how many are there and what colours are they (although colours can be deceiving, it is somewhere to start) ?

Cheers.

THere are no wires at all... lol its just a coin door with the metal where all the wires need to be hooked up


CheffoJeffo:

OK ... that's a bit different ... if you open up the back and look inside, there should be a wiring harness that the PCB (board) is plugged into. From there, wires will run to the monitor, the controls and power. ARe there any wires connected to the harness that are just hanging loose (e.g. not connected to anything) ?

I would advise doing this with the machine powered down ...

Cheers.

EDIT: There appear to have been two different types of GnGoblins boards ... one with spots for two coin mechs at pins 18/V with seperate coin grounds at 19/W ... according to the manual, those would have two gray wires at 18/V and two black wires at 19/W. The other type has a single coin spot at 18 with a pink wire (again, colours can be misleading), but nothing at 19.

ALL the wires that make the game function are there.... just not the wires to the coin mechanism to the main power supply or whever i connect it
