I have a HRC on location and having some issues I don't understand. First let me say CPU has no acid damage and has NV Ram installed. There are times when the game gets turned on it will say open the coin door. (Like you would think it has dead batteries) But here is the thing, it never looses its settings. Second, All the balls were stuck in the roulette wheel, once in test I tested the optos manually and they worked fine. Game is working again with no errors, but will do the same again in the future, as the coin door issue has been going on for sometime now. I am sorta lost on this. Anyone have any feedback? Thanks

Also forgot to mention all voltages are good on I/O board and to CPU
