Jumping Jack F relay (resized).jpg

#1 1 year ago

E-Delay Relay on my JJ stays energized on start up and drop target coils fire constantly even thought they are all reset (up position). Score motor rotates constantly. What is causing that coil to stay energized?

We're talking about the F/"E" Relay Delay relay, right? That would cause your Score Motor to run and drop targets to reset via the O/Outhole relay which is probably also stuck on.

Start by checking that the two switches in the red box are actually opening. They both need to open to let the F relay relax.

Well with help from Dave M. My JJ lives again. Still has some issues but nothing major I don't think. Looking for a copy of the instruction card.
10,000 unit is getting a extra pulse which turns the score reel on player one to 1...Any thoughts

Need to rebuild my JJ pop bumpers need skirts and caps. Steve Young doesn't seem to have them listed. Any suggestions?

Look again, Steve has everything you need.

caps: '100 Points' In Blue or Red A-11425

skirts: looks like Blue 6 hole?

So almost done with JJ. Player up unit sticky. Does not switch to player two or back to player one unless I do it manually. Not sure I want to attempt a complete disassemble. May just try and lube the pivot points. Any suggestions or pointers. Still getting that extra pulse on start on player one that turns the 10M reel to one?

Hey there! Got a moment?
