I am stumped. When right flipper button is pressed the upper flipper functions normally, the lower flipper very slowly moves to the eos position, when released both flippers retract normally. The left flipper functions normally.

Things I have attempted:

I have cut diodes to see if it was a diode issue on lower right flipper (problem still exists)
I have changed fliptronics flipper boards (problem still exists on right lower flipper)
I have changed the board in the head (used another fliptronics board from functioning DH), weird thing is, DH board when installed in WH2O I get the same lower right flipper issue but when installed in DH it works fine. To add to that the WH2O fliptronics board when installed in DH it works fine (meaning: both boards work fine in DH but not in WH2O).
I have pulled fuses on fliptronics board and all test fine
I have powered the flipper on and when game is shut off the flipper retracts (checking to see if a mechanical issue or electrical, which this test makes me believe it is an electrical issue).
I have made sure there is nothing binding the flipper, it does move freely with a new coil sleeve.

Not sure where to test from here and am hoping someone else can give some ideas.

Thank you,
Loren

Already tried the flipper cabinet switch to the other side.

As far as wired wrong, I guess it could be but have not had a problem the last 4 years that I have had it.

I was going to either replace the coil or try new diodes to see if I can get somewhere with it.

What does it mean when the "power winding is open"?
