My JJ has only power to the back box illumination. No power in any playfield relays. Fuses are good. Transformer looks crispy. Tilt and player 1 are lit in back box.
Just sent for schematic. Any ideas.
Thanks

Yes, credits on the credit unit. Does not start when I hit the replay button.
Thanks

Thanks. I will check it out

So this is the transformer in the JJ. Not sure what the voltage should read on the lugs. Trying to find power so I can jump the "S" relay to see if the game will start. Schematic coming in mail. there is power at the main fuse in the bottom of the cabinet. Any help or ideas. I could take the door apart to see why the replay button is not doing anything. Not sure what that would accomplish.
Thanks
Frank

Thanks. Tried that nothing happens.

Ok got game to start tilt switch in bottom of rabbit stuck closed. Score motor now runs
continually

F and O relays fire continually along with target reset coils when start game is activated . Games remaining does not count down. Looks like some one jammed the switch

Ok. What do I need to do to fix it. Thanks

Yes . Seems to not release the tension. May try taking out that screw it is stuck on

Thanks for the update. I think the zero switch on the score reel may be dirty score reels try to reset at start up even though I set them all to zero.

I was able to release the tension on the stepper unit. Unit is not seized but does move correctly when I activate the solenoid. Seems it is not engaging the gear correctly. Does not turn credit wheel. Seems to be stuck. Will need to take it apart and clean and reassemble. Bakelite is still bent. will have to fix that.
Thanks
