i did a rebuild on my STTNG's upper flipper and it didn't solve the issue of double tapping when i try to hold it. i'm going to try a new coil, but are there any other options?

Try cleaning the contacts on the flipper button.

Clean and regap the eos switch on the coil and clean/adjust the cabinet switch as well. Or replace the switches if the contacts are toast...

Could also be a loose connection. Re-solder the lugs and the diode.

Try the easy things first. Cleaning the contacts on the flipper buttons and EOS switches. Also make sure the EOS switches are adjusted appropriately. Then you can move on the the more complicated stuff.

Sounds like a loose diode on the lugs. Check to make sure they are all getting good connections.

Sounds like cold solder on either diode or lug wires, could also could be bad EOS switch as everyone has already said - Also check the fliptronics board could be something loose on there. (dont have a fishtales but I think its flipptronics)

for my STTNG upper flipper i put a new switch by the coil, the old was practically had a hole in it from making contact in the one spot! the power on my upper flipper is great due to the rebuild, i have been picard maneuvering away! it was so weak before i could never hit the delta quadrant. but the double tap persists. i'm pretty poor/new at soldering and DID reconnect one of the wires to the coil because it wasn't even on there at all previously. the connection seems ok but how do "cold joints" happen? because i likely did it! i'll snap a pic of my rebuilt flipper area today as well. the diode seems to be on there good as well. thanks for all the help, and for the guy who started this thread...?

here's some pics, just resoldered the switch, orange wire was loose.(like i said need practice soldering... )
got super excited that it was a quick fix but, oh well, not the switch.

i cleaned the flipper opto board as well, so its safe to say thats not the issue (plus the lower right flipper works with no hitch)

jespo_19,

I know this is off topic, but why didn't you use a super flex for the lock insert? I think it would be better illuminated that way.

good call gweem i DO have another one, DOH!
NOOO.... i have 555 flexes no 44's!!!

WOW, i resoldered one of the lugs (the one i had previously done) wasn't loose but i did it anyway. now when i fire the game up and press start no ball is fed to the launcher and both cannons simultaneously fire once about every 2-5 seconds. seems like i've angered the pinball gods today...

sorry to yank everyones chain around, i discovered, no diodes at all on there!?i remembered them being there before! sorry everyone, rookie mistake and careless. it may have cost me... does anyone know what happens to a game when no diodes are on a coil? cause right now it acted insane when i turned it on. no flippers at all, weird ball searches etc. i ordered a new coil from pinballlife so we'll see i guess. i'm going to avoid touching it till the new coil comes i don't want to mess anything up further. am i blowing it out of proportion doing major damage etc? or should the new coil w/diodes fix the issue? thanks again guys, i feel terrible for overlooking this NO DIODES......

Just order some diodes. It doesn't sound like you need a new coil.

I have the same problem as you Mick, not sure if you had any luck...i posted another thread here, as i am too new to pins...here is what i tried so far to no success...

Cleaned opto eyes on boards/switched boards problem still was there.(right flipper chatter no hold).

Replaced EOS switch gapped to .062 , replaced flipper spring problem still there..

Replaced coil,resoddered ..problem still there...

This is where i am now, am over my head! I pulled the fliptronics 2 board and tried to replace the Tip102 transistor on Q11...now neither flippers work!

may buy the PINLED fliptronics 2 board

Following up on this, My Dr. Who machine was acting similarly and when I investigated,
I could see the flipper hold coil arcing at the lug. Re-soldering took care of it.

my problem was completely fixed by the new coil. i have two diodes here i'm going to put on the old coil and test though.
