Hi all. Rookie question.

Machine in great shape overall. The third flipper got weak, then finally stopped working (it would just "wiggle" when the left flipper was activated.)

Last evening, the kids were playing and let the smoke out of something inside (pretty smelly.) They said the 3rd flipper started making a fast tapping sound just before they smelled the smoke.

Nothing unusually dark or "burned" smelling inside - on that flipper or anyplace else. Suspect the solenoid on this flipper is bad? The rest of the mechanism seems OK.

Any advice? Anyone have a good way to figure out the proper PN for this solenoid (no numbers on it, i don't have the schematic for this machine.)

THANKS!

Thanks guys.

Maybe this means nothing... but when i manually move the left and right flippers, there's resistance. When i manually move the third flipper, there's no resistance at all.

if i change the third coil, should i also change that EOS? What about the EOS on the left flipper... adjust or change this one first?

THANKS!

Chris

Thanks all. A bit more sleuthing...

- Opened up the machine and found the secondary EOS switch on the left flipper was very dark, quite mangled, and was "stuck" to the other leaf. Assume this was the switch that arced/smoked. (pic attached)
- cleaned the contacts a bit (just a piece of paper for now... i have no file on hand)
- tightened the two set-screws on the third flipper
- powered, on, and everything seemed to work as normal. Assume this means the coil on the thrid flipper is ok?
- after a bit of play, the set screws on the third flipper loosened
- occasionally when activating the left flipper / holding it down, the third flipper would fire multiple times

So my question for you smart folks: do i replace the secondary EOS (i think this is the term) on the left flipper? do i need a full rebuild kit for the third flipper, or should i just replace the lever (assuming new set-screws will tighten and hold better than my existing ones.

THANK YOU!!

Thank you! parts ordered!

Good news: replaced the left flipper Secondary EOS switch and the EOS switch on the third flipper, and tightened the allen screws as tightly as possible. Left flipper and third flipper all work perfectly.

Bad news: the EOS on the right flipper had dark, worn, pitted contacts, so i used a flex board to touch it up. When i powered up the game, the right flipper does not work at all - no spark, no buzz, nothing. The switch on the flipper button has worn contacts, but no worse than the other flipper button.

So: is there anything i could have messed up on the left/3rd flipper that would effect the right flipper? or, did filing the EOS switch contacts damage them?

THANKS!

Well... rookie oversight then.

so if i touched an EOS or flipper switch with a flex stone... its time to replace them, correct?

So i have a right-side flipper that isn't working at all. I used a flexstone on both the EOS and the flipper button switch (white/chalky, look pitted - EOS pic below.) Per videos and articles the switches both appear to be adjusted properly but the contacts are pitted/worn.

Should i change the EOS and flipper switch? Would these worn contacts cause the non-function condition (no buss, spark, anything.)

I also replaced the left side EOS and third flipper EOS successfully - all is working well. Could i have damaged something that would cause my problem on the right side?

Appreciate any diagnostic advice anyone has. I can swap parts carefully but i'm no schematic reader.

THANKS!

Chris
