Quoted from Sammy31:Hey owners.
I'm looking for popper assembly a-16580 (left side VUK).
Thanks
Found one
I have a weird issue that I hope someone can help me resolve with my JD.
Whenever the left "missile" plunger activates, my left lower flipper loses power momentarily. I have no issues with the flipper otherwise.
I checked to see if the plunger was hitting the flipper opto (they are very close but are not touching). I even raised the playfield to make sure but flipper was not touching but it still loses power when missile plunger activates.
Wiring seems all correct. Checked schematics for any intersect points between the 2 devices but didn't notice any.
I'm thinking a spike in power on that line is somehow killing the power to both my hold and power windings in my coil or it is causing the opto in my flipper button to turn off (simulating releasing the button)...
My next step is changing the opto on my flipper board maybe it is weak.... unless any of you have better ideas?
Thanks for any help.
Quoted from cynric:Depending on how your optos and flippers are wired it might really be the vibration of the coil messing with the opto. The left board on JD is a unique one with a metal interruptor. If the flipper that loses power is the one triggered last when slowly pressing the button in, you might want to try bending the metal piece tiny bit out of the opto so it triggers a little earlier. Or rewire the optos so that the lower flippers fire first and the uppers 2nd (thats the way I like better)..
Apart from that crosstalk from the shooter coil return to your flipper coil wiring comes to mind, but I doubt that would have a really noticeable effect. Maybe if the diode on the shooter coil was bad, but that would probably have fried the coil driver by now..
Thanks for replying. Not vibration as I lifted the playfield away from the Opto board and tried it. The lower left fires first and then the upper left... My left shooter coil does not have a diode. Although I don't think many of those smaller coils are supposed to have them, am I wrong?
Quoted from PinRob:Can you snap a pic of the lower left flipper board inside cabinet?
It's really tight in there with that extra fire button. I will probably have to pull it out to get a good pic. Will try to get a shot of it this weekend.

Quoted from luckymoey:Pretty sure that’s a silk screened cabinet so all you really need is the PinGuard protectors with properly tightened leg bolts.
This is wrong. Pinguards make new wear higher up.
Use the Pinguards to cover up the old damage but only after you have placed some of those metal leg spacers underneath to keep the pinguards away from the cabinet.
