    Back again with a new issue. You guys are amazing.

    So it seems the left flipper might be getting stuck any idea where I can start to fix this?

    Shared a link with video of What's happening.

    Thanks all.

    If you shut off the machine and manipulate the mech by hand (sometimes from the bottom of the pf) you can figure out if it’s mechanical binding or an electric issue.

    make sure your cabinet flipper contacts are clean and not worn away/pitted.

    also check your EOS switch contact gap. Post a pic if you can of the flipper assembly.

    also check the windings on the coil, that they are well soldered in place on the solder tag, also the coils' diode. Post a pic of this too if you like?

    Not getting stuck but appears to be chattering. That is caused by a problem with the hold coil. Look at the hold coil wiring to see if one of the thin wires is breaking loose. The hold coil are the thinner wires of the flipper coil that are normally shorted out by the EOS switch. Because the wires are so thin they tend to break over time. When the hold coil breaks the flipper chatters when the EOS cuts out.

    Could this be the issue? Brown wire on the right

    And is that thin wire the hold coil? On other picture?

    Thanks all for advise finally trying to sort it.

    sorry couldn't see cabinet flipper contacts, also can't tell colour of wires in second pic. but there is a wire on the right hand side solder tab that looks to be just hanging on?

    I will try get better pics. Yeah they are brown wires and it is just hanging on.
    I will try to repair that. Fingers crossed

    Nope didn't fix it it's never simple is it haha.

    The wiring on the flipper button looks ok I think.

    my initial concern was the cabinet flipper contacts, not the solder tabs, but looking at the pic of the switch it doesn't look like it is wired correctly.

    there should be a common colour to both switches on one solder tag (orange), and a different colour for each the left and right pair, red for right and blue for left.

    it's still hard to tell from the picture but the extra switch on the switch stack should have 2 wires and a diode, and it appears to have 3 wires joined.

    the 2 the same look orange and appear to be sharing the flipper switch and the maze change switch? This isn't correct if it is.

    so again, the left flipper switch should have the 2 orange wires on 1 solder tab, that being part of the flipper switch, with blue being the soldered to the other solder tag, the other part of the switch.

    the maze change switch should have 3 solder tags with 2 coloured wires connecting to a solder tab (1 to the anode side of the diode), one to the long leaf blade and the cathode of the diode on it's own solder tag, no wire.

    it may well be, but that component joining solder tabs doesn't look like a conventional diode.

    are those 2 orange wires going to one solder tab, or two?
