Earlier, I was playing a friend’s S2000 upright machine and every 6 spins or so, the machine wouldn’t finish its spin, and as a result the Reel tilt message would come up. I looked at the machine for him, I shut it down, spun the reels manually. They weren’t in the best,(TRUE) balance. I tried another set of reels and the same results occurred. I secured any loose wiring and made sure nothing was hitting the reels. When this was happening, it was on random reels. Sometimes the 1st would stop ok and then a reel tilt. Other times it could be the 2nd. or 3rd. reel. I had this happen to one of mine and It seemed to diminish drastically after I put on a surge protector. Could this be a power supply issue or something in that realm? Anyone else that can shed some light on this issue, would be Appreciated.
