I have an IGT s2000 wild cherry slot machine. It has been working fine and just the other day the MEI SC 6602 bill accepter stopped taking bills. I have tried 1's, 5's, 10's, and 20's... I am getting a blinking green light on the MEI bill accepter. I ordered a new bill accepter and replaced the head and am getting the same blinking green light... When I read the manual for the MEI bill accepter, it says that it is not connecting to the machine. I went into the setting of the slot machine settings to make sure that the bill accepter is "enabled" and it is... The machine is taking quarters without a problem. Can anyone help trouble shoot this? Thanks in advance!
