Quoted from SkillshotExhibit:However, even with the new coil the right bottom flipper is making a kind of skipping effect, extra flips and the flipper unexpectedly drops down.
Your flipper "Hold" coil, the wiring, or the transistor on the board isn't activating.
Fliptronics will activate the power winding (*) to raise the flipper, and then when it sees the EOS switch close, it will activate the Hold winding. If the EOS opens up, the Fliptronics board will activate the power winding again, thinking a ball hit it and knocked the flipper down. It will do this twice - that's the "skipping" effect (bouncing) you see, and then deactivate the flipper until you press the button again.
Check the coil's wiring and the hold drive wire.
