1973 Gottlieb King Pin - score motor never stops


OK, I'm helping a friend with a 1973 Gottlieb King Pin. 1 Player EM.


Interesting tidbit - it's HUO, bought new, only has 6000 plays.


Cabinet, backglass, playfield - completely pristine. Amazing
condition.


Anywho...


Turn it on, push Replay button in center of coin door, score reels at
zero, ball count unit goes to zero, game credit goes to 15, then down
to 14, ball kicks into shooter lane, GI and backglass lights are on
and 10-bank targets will reset, but...


- score motor never stops spinning, no power to flippers, slings, or
pop bumpers.


I think the free game knocker is also firing continually.


What do I do now?


Sorry - new to EMs.

1960s & 1970s Gottlieb Start-Up Sequence.
Games with score reels.
Inserting a coin or pressing the coin door start button (Gottlieb calls this the "replay" button) activates the "S" (start) relay. The start relay will lock on from its own switch and a score motor switch.
The "S" relay will energize the main hold relay to illuminate the game (if this is the first game after power-on).
The "S" relay will start the score motor running.
The "S" relay and the score motor increment the total play meter.
The "SB" relay (the secondary start relay) is activated through the score motor. The "SB" relay energizes the reset relays ("Z1" and "Z2"). If a single or two player game, there may be only a "Z" relay.
The "Z2" relay will reset the player 3 and 4 score reels to zero through the score relays (4 player games only). The "Z1" or "Z" relay will reset the player 1 (and player 2 if present) score reels to zero through the score relays.
The "SB" relay resets the player unit through the score motor.
The "U" relay resets the reset bank (or Ax, Bx, relays on 1975 and later multi-player games and Ax on single players) through the score motor. It also resets the bonus unit or drop target banks (if the game has these).
On multi-player games, inserting more coins or pressing the coin door start button activates the "PBx" relay, through the score motor. The "x" represents the player number (from two to four).
If the ball is in the outhole, the "O" relay activates. The "O" relay, through the score motor and a switch on relay "XB", will kick the ball to the shooter lane. Note: the "O" relay will not activate unless the bonus unit (if the game has one) is reset to zero (there is a bonus unit zero position switch).
When the ball re-enters the outhole after game play, the "P" relay kicks the ball back to the shooter lane. Switches on the "XB", "ZB", "P" relays and some score motor switches advances the player unit (if present) and player relays ("PBx").
 
Found it !!!!!

There was a quarter stuck in the right hand mech pinching the leaf switch there closed.

Game now plays !!!!

Whooo Hooo !!!!

OK,

Two new questions:

1. What is the correct way to put this game one Free Play? I know PinballNinja says to permanently bend a particular switch closed. Which one?

2. How do I change from a 5-ball game to a 3-ball game?

Thanks again,

Burnt Chime Coil was replaced today (was kind of a bitch), but nice to have all chimes working again, and flipper contacts filed clean and flippers aligned properly. Still have a slight buzz in left flipper. Bumpers and slings need to be adjusted and cleaned. Starting to play much better. Inserts have pretty bad cupping.
