Quoted from guymontag451:it is in great shape and came with new boards installed to replace the notoriously horrible originals.
What boards are in there Ni-wumph or Pascal Janin?
Can you post pics of the boards in the head?
So you can't add any credits from the coin Mechanism?
Did you call the warehouse? Seems like a connector issue since it worked and then home it didn't.
I have a Countdown . The coin and start switches go to A1J6. I would look at the contacts in A1J6. Do you have the schematics or manual?
