Bought a neglected Gottlieb King Pin... so I got it sorta up and running... it starts a game... but it has a weird issue... if you hit an outhole or a drop target it andvances the ball count to the next ball... originally when I got it running, it would start a game with no scoring or flippers... does anyone have a pic of the Ball Count unit and the switches on it... i think the switches on mine are not right... as in what should be open or closed... also... I think a plastic insulator that pushes two of the long leafs is missing... THANKS

OK... so I have narrowed it down more... every time you score more than 500 points on a shot it will advance to the next ball... any ideas?

Anyone?

I do not have a schematic...

checked the ball trough switch and it seems fine... it only happens on high scoring... does not happen when I manually hit the scoring units in the back box...

Mostly happens on the kickout holes and the drop targets... like every time....

The problem happens whenever the 500 or the 5000 relays are tripped... I did this by hand...

OK... I found a score motor switch on the bottom stack where it is marked 2... every time it it activated it moves to the next ball.... is this supposed to happen? Also when I drain a ball the score motor also spins? is this correct?

The switch I found is normally closed... I found a few other switches on the score motor that were not opening when they were supposed to... I think from it sitting so long they got used to being in one position... so I adjusted those... still no dice... so I will check every switch on the score motor and see what else I can find... When I isolated that one switch it did not advance.... I have now noticed it advances the ball any time the score motor is engaged...

I think I got it!!!! a combination of switches not opening on the scorer reel from having sat so long and intermittent issues with the ball drain switch and the trough switch... also had a few weird slam switches... specifically the one on the coin door and the one in the back box... so they are wired shut...

Appears to be working... now to clean it up and replace bulbs... and see what I can do about the crappy back glass...
