hi just brought a barcrest viva las vagas and got it working, (see other post). got my self a refill key but it wont refill!! the door is shut and key is turned the message says "cash refill", but i will not accept any money, the coins just go straight through. not a major problem but annoying. also i have cleared the meters using the refill key (back door open) but now every time the machine is off for a while the memory is cleared, so i was wondering if there is a battery somewhere which needs replacing, but cant find anything. its running on a mpu4 board if thats any help. thanks in advance
