My JP has just started acting up.
During start up it does its test and after the t-rex test is tells me too many balls for a split second.
You start a game and it does not kick out a ball than goes in to search mode. Turn it off and on again, let it reboot and it might work once in a few tries, but when you drain the ball it goes into search and than kicks out the next.
Have some more issues.
The bunker coil fires two more times after it kicks the ball out. I have noticed that when you hit the bunker shot it some times activates the control room.
I have looked at all the switches. Have I over looked something?
Thanks in advance for the help.

Now we got some crazy stuff. Started game (have not had on in about 5 days) Played great until. Have on 5 ball. Played and got tri-ball on ball 3 (not my best game, just testing). All drained and started ball 4, no ball kicked out, keep doing cycle. WTF!! I took ball out and placed in kick up and it played fine. Ball ended and went to 5, same shit. This time i took ball and placed in shooter lane, played fine. end game. Turned off, started again (flashed "to many balls")and played a full game. Started another game and made it to ball 3 , again the same as before.

must have a early production because they are on the switch. All switches test good. Maybe board issue. That will be my next.

Thanks all. I will check all diodes , voltage, and switch adjustments. Hope to get to it this weekend.

No worries. Still have not got to check it out yet.
