Just did a rebuild of the lower flippers on RIBON, actually more like a replacement as I bought the assembled assemblies from PB. After the rebuild it's sort of like there is no low power, game works and flips fine, but when the ball hits the flipper with a bit of speed and the flipper fires again almost like a trampoline effect. I can pull the held flipper down by hand quite easily. It's happing with all 3 flippers (even the one I didn't swap) checked all the fuses in the game and there is power for the 20V at the board. Any suggestions on what to check next?
