HI All,
I recently acquired a Bride of Pinbot in average condition. Cabinet has been nicely redone, but the play field and ramps need a work. All is registering and working electrically; except the left flipper. Left flipper switch does not register in switch test mode, all other switches register correctly. The left flipper specific fuse is good, and I have replaced it to be sure. At some point in its life, it has had its flipper mechs updated to use the more modern wpc style; i noticed that on the left flipper the EOS switch isn't engaged when the flipper is extended. This would effect the life of the coil, but doesn't explain why the left flipper cabinet switch does not register.
Any ideas? I am stumped.

Thanks in advance

Thanks Fatdirk
I have reseated all the connectors. No change. Flippers are still pre-fliprtonics if that wasn't clear.

No. No flipper operation, no switch registration in switch edge test mode. Coil plunger moves freely by hand.

Had a better look at this tonight without being exhausted. Exhausted brains do not work properly and this is evidence as such. Re-tested fuses, F101 blown. Replaced fuse, flipper button registers, engages coil and blows fuse. Will get diodes and fuses on the weekend, resolver coil and continue. Suspect bad solder join and blown diode on flipper coil.

Replaced coil diodes (yes correct band direction). New fuse; flipper fires on button press and blow fuse immediately. Ideas? All other functions work

No I didn't Travish. Will tonight. It's quite possible with the eos never being engaged due to the wrong pawl on the flipper

I know about the pawl. Stated it's wrong in the first post. Will be replaced with next parts order.

Bingo! Shorted coil. Reading of 1 ohm
