Okay...you have some kind of coin comparator. 

The JAMMA spec, IIRC, says that coin switches are normally closed.  So that's what this device is doing.

Mame, OTOH, has coin switches as normally open.

How you could correct that with this device, I don't know.  but I do believe it to be working properly within the JAMMA spec.

Ah ok so I could configure mame to expect it as always closed?

Also, the coin just drops straight through to the reject when I put one in, and the bulb (which I bought brand new so it isn't broken) doesn't come on. This leads me to believe it's broken, but could there be another reason?

Thankyou

I don't *think* so, though I've been wrong before.

Removing it from an actual JAMMA board may have interfered with the way it operates.  Sounds to me like it's not being powered, so it's rejecting all coins (since who wants to pay to play a machine that's not plugged in?) and that also affects the light.

Do u have the manual for the credit board?? If so it will say what the jumper settings on the board are for, and you may have to change one of the jumpers??

I'll have a look tonight what wires are going into what pin on the jamma harness. I am using J-PAC which I assume emulates a PCB's pretty well so surely that can't be the problem? Or can it...

I managed to find info on the jumpers online and they are set to take 10p as a credit
