Gottlieb King Kool advances to player 2 when 1000 pt is scored

Please help with this nightmare King Kool.

In a 1 or 2 player game the game advances to player 2 occasionally when the 1000 pt relay is activated. Only happens when 1000 pts are scored. Does not happen when 10s 100s or 10000s is scored.

Doesn't erroneously advance again (it does not go back to player 1 when 1000 is scored.)

Happens pressing the L relay manually - or if 1000 scored on playfield. There does not appear to be any shorted wires or issues with the L relay stack.

I can see the player unit advance coil engage when it happens.

As expected, the score motor does not run when 1000 pts are scored - and I verified score motor 1a second switch is open at rest.

The player 1 and player 2 reset switch stacks on the player unit seem to have correct gaps and the game otherwise scores and resets correctly.

Looking at the schematic I can't see a correlation between 1000 pts and the player unit advancing.

I attached a pic of the player unit part of the schematic.

Any ideas where to look? Thanks!

I’d look st the player 1 1000 reel zero switch to make sure some other wire isn’t touching. If that got energized, it would carry through to the advance player unit.

Good luck,

Check your 1000 point score reel again. I had a somewhat similar issue with a Gottlieb game once. The switches were all opening and closing properly on the score reel but a fish paper insulator was missing between two different switches. When they were touching, weird things happened with the player unit.

Ah hah....you were all right on track. The arm that operates the switches in the player 1 1000pt score reel was in the wrong position. Fooled me since the reel operated correctly (reset, scoring, carryover) otherwise. By comparing it to p2 1000 reel it was easy to spot the difference. Re positioned the arm and mystery player unit advance has stopped. Thanks for quick replies!

That’ll do it

Glad that you fixed it.
I love the graphics on that game but those double flippers with the gap don’t do it for me...

Do you know how that was causing the player advance in your original post? That still seems like a weird symptom to get from a score reel switch being off (although I don't know anything about this game or what's on that stack). Just curious, I can't stand mysteries!
