Johnny Posted January 7, 2022 Share Posted January 7, 2022 Hi , Need some help with a flipper problem, the right flipper on my WPC95 will not hold up when flipper button is pressed, it double flips when pressed, Thanks John Link to comment Share on other sites More sharing options...
Administrators Arcade King Posted January 7, 2022 Administrators Share Posted January 7, 2022 Could be a wire off on your coil that needs resoldering or the hold winding on your coil has gone open. 1 Link to comment Share on other sites More sharing options...
skids Posted January 7, 2022 Share Posted January 7, 2022 Sounds like the End of stroke switch is too close Link to comment Share on other sites More sharing options...

Gemini2544 Posted January 7, 2022 Share Posted January 7, 2022 Does it flutter when the button is held on? If it does the hold winding on the coil has a break somewhere. Link to comment Share on other sites More sharing options...
Johnny Posted January 8, 2022 Author Share Posted January 8, 2022 Hi I have replaced the coil and adjusted the EOS still the same issue, Thanks Link to comment Share on other sites More sharing options...
Boof Head Posted January 8, 2022 Share Posted January 8, 2022 Try swapping the flipper button opto boards. Does the problem move with the board? Link to comment Share on other sites More sharing options...
Johnny Posted January 8, 2022 Author Share Posted January 8, 2022 Already tried, it is not the opto board, Link to comment Share on other sites More sharing options...

That just reminded me of flutter I once had on a I.J. Cleaned the optos with some Windex and a cotton ear bud fixed it. Link to comment Share on other sites More sharing options...
skids Posted January 9, 2022 Share Posted January 9, 2022 Swap the whole right flipper mech with the left flipper mech, see if that changes anything Link to comment Share on other sites More sharing options...
Autosteve Posted January 9, 2022 Share Posted January 9, 2022 Double flips as in looks like it bounces and then holds up or double flips and doesn't stay up even though the button is still held on? What does it do in flipper test?.......I find better to do this test in manual advance, not auto and in your case I would select the effected flipper "power" and let that pulse a couple of times. now put your finger behind the flipper so it stays nearly up and advance the test to "hold". Don't assume this "hold" test will pull the flipper all the way up thus the finger behind to test the hold circuit. See what happens and get back with the results. Testing the flippers this way bypasses the cabinet switches or optos. The EOS switches are not used to control the flippers power in any way on WPC. They are solely there to log errors. The fliptronics board switches winding power on timing. The EOS idea on WPC was "originally" to stop a fast ball knocking back a flipper when it was in "Hold" but this didn't effect Williams flippers like it did on DE machines that only used 9vAC to hold up a flipper on there single winding flipper coils so that part of the flipper control was removed. You can short them out perminantly or leave them open perminantly, you'll just get EOS error codes coming up but the flippers will work perfectly without the switch working correctly. I'm putting my money on a faulty driver transistor on the fliptronics board or something related with the fliptronics board including ribbon cable but the above test will go a long way to ruling out the simple problems.

Left and right flipper mechs have different footprints and rotate in the opposite direction to each other. That's what makes them left and right...

Boots Posted January 10, 2022 Share Posted January 10, 2022 (edited) I would always check the coil windings with a multimeter first as they are the only thing subject to vibration after that the hold transistor on the fliptronic Edited January 10, 2022 by Boots Link to comment Share on other sites More sharing options...

Change the coil and eos over then Link to comment Share on other sites More sharing options...
Gemini2544 Posted January 10, 2022 Share Posted January 10, 2022 Could be the most missed reason, a mushroomed plunger, bad back stop & a sticky coil sleeve. Link to comment Share on other sites More sharing options...
