IGT embedded bill acceptor not working

[Jim]

I still think you have a Western Money system installed in your machine. Western Money systems used JCM heads in their systems, in your case a DBV-145. what writing is on the chip that you posted in reply # 8.

I see where the interface is plugged into the motherboard, where do the two white wires terminate, it appears they are going over to the motherboard as well?  I see where the two black wires are hooked directly into the AC terminal block to provide 115 to the transformer.

So you are getting power, the interface is getting to the board, unit should make a complete cycle (several types of noises) . problems with units were in the area of the serial db connector that mates with the bill stacker( the metal unit that plugs in).

Don't have a clue where that plug should go? appears that all the connections are in place.
