I was having problems with the right flipper on my FH. It would become progressively weak during a game. I took the flipper mechanism apart and noted that the coil sleeve was cracked. I put in a new coil and sleeve without rebuilding the flipper and noticed that the coil was very hot after a few plays. I just rebuild the flipper (with a rebuild kit for FH) and the flipper now works. The problem now is that the left flippers will not work. I checked the F101 fuse and cleaned the flipper button switch and this has not helped. What would cause the left flippers to stop working after a full right flipper rebuild? They were working prior to the rebuild.
