I have a Gottlieb King Pin. The issue is when the 5th ball goes in the ball return it gets kicked back to shoot. This leaves it in the incorrect position to start the next game, if I am understanding everything correctly. I have been checking all of the relays and switches, but feel like I am missing something basic. Any suggestions? Thanks!

Check your Ball Count Unit. It doesn't seem to be going to position 6. Look for poor contact, bent finger, etc.

Yes, as currieddog said it is usually misadjusted or dirty contact at ball count unit. But also check and clean the 3/5 balls per game adjustment plug and make sure switches are clean and switch stack screws are tight on outhole/ball return relay (usually "O").

Hi Dgoral
I would like to support currieddog (post-2) and Tuukka (post-3). In the JPG here we see: Every ball played, then lost enters the Outhole, closes "my green A" --- the O-Ball-Return-Relay is made to pull-in. "Normal balls (NOT the last ball)" are then kicked over to the Shooter-Alley - on the way over they roll over "my green B" - the Add-Ball-Count-Unit is made to fire, step up.
But loosing the last ball: "my blue line, wiring" comes into action. You may have to check all of it. Greetings Rolf

I had the same problem on the same game. Are sure that the ball count unit is clean and operates smoothly. If it is the least bit sluggish, it won’t move to the end of game position before the kicker fires. Also make sure the score motor switch 1A isn’t gapped too wide. It’s basically a race between that bal count unit incrementing and the circuit that kicks out the ball.

Thanks everyone. It seems like this took forever for me to resolve. I think I went over everything suggested multiple times. What I think finally fixed it was taking the ball count unit apart and really cleaning the contacts and wipers where there had been significant wear to the copper pads. I realigned it as well, and maybe that helped also. I had already cleaned this before but must not have done it well enough. Thanks again for the support!
