I recently installed the Mars conversion kit from Etowah...I went trouble free for about a month. The error code I now have every couple of days is 3 flashes pause...then 5 flashes on the controller. The Mars acceptor just flashes twice if that helps. I can run 50-60 dollars through with no problems...accurate payouts...then come in the next morning to the same error code. Does anyone have any suggestions? I would really appreciate it. Thanks, Justin
