Just like the title suggests. I have a 5 reel Lucky Lady bb1. I have tried almost everything I can think of.
I have a working JCM bill validator in the machine. I want to upgrade it to the MEI. I have set up the MEI up in other machines to make sure it works. After clearing the machine, I set up the MEI in devices. It usually will show a COMM error until I power cycle the machine. When it powers up, there are no tilts, but the BV will not take any bills... will not even act like there is a bill, it does nothing. I have tried 2 completely different MEI setups including the daughter cards. I have tried replacing the MPU from the green one, to the blue one. I even swapped out the lower board that everything plugs into... and I get the same result.
I have tried the following...
1. Checking the jumpers on the board
2. Swapping MPU's (with one from a machine that accepted the MEI
3. Different clear card versions
4. Power Cycling the machine
5. Swapping the board that everything is plugged into.
Am I left with replacing the entire harness?
Is there something I am not thinking of?
