I have been troubleshooting a flipper rebuild on my BK2K due to improper wiring. After correcting wiring, and replacing diodes, I am not blowing any fuses. The lower right flipper works properly and the upper playfield flipper works, but does not hold. It seems to flip strong, but falls right back to rest position. The EOS switch is closed at rest and opens close to an 1/8th inch at full travel (new at flipper rebuild). I also just switched out the coil, but it hasn't helped. The flipper switch(lane change switch) from right lower playfield flipper seems to be working, as the lane change works during a game. I'm at a loss. First picture is upper playfield flipper, second picture is lower playfield right flipper.
