Thanks for the replies,
Thats a good tip about the switch Firepower, will have a go at hooking that up, I feel robbed when I win a free play and dont hear the knocker.
So its normal not to have a knocker on free play I get, but I think I have another issue with no credits been awarded on points when I have set machine to coin play.
Would this possibly be a connection problem between master display board and cpu board?
Cheers
Dave
