Hi.
Don't have that pin, but think if you raise the play field, start a game, or start game first, close that roll over, and watch under the play field, you shud see what relay fires. that would prob be the culpret???
would suspect a dirty, mis adjusted switch for the lights.

Hi malachi88
great, ipdb has the schematics: http://www.ipdb.org/machine.cgi?id=1743 - I show "marked green" the INITIAL-Current wiring - it works in Your pin.
Dr_of_Style suggested to look (underneathside of playfield (?) ) for the On-Bumper-Relay.
When You press the armature of this relay: The Bumpers are lit.
A short wire runs from the "Coil on On-Bumper-Relay" to a "Switch mounted on the relay (my blue 'A' " - then a wire runs to "Through Switch (my blue 'B', probably under the Apron whre the Ball rolls over to the Shooter-Alley (?) )" - then a wire runs to "Switch on Game-Over-Relay, my blue 'C' ".

A Switch may be maladjusted - a contact-point may be oxidated - a wire may have broken-off somewhere (?) - greetings Rolf

I believe that switch should be normally closed.

Hi malachi88
I do have problems understanding - post-4, pic-2 --- what it is for ? The Switches in pic-1 look strange - when mounted: Are they part of a Switch-Stack ?
I have never seen an WILLIAMS "Through Switch" - I am not familiar With "Add-A-Ball" pins.
I show a Gottlieb (Surf Champ) Through-Switch - YOUR Through-Switch is an 3-bladed "Make-and-Brake-Switch***, has soldered-on on the MIDDLE-Blade: Wire-color-93-grey-yellow, Out-blade-1: Wire-color-12-1-red-blue, Out-blade-2: wire-color-89-1-black-grey.

Make-and-Brake-Switch*** - very strange - see post-3, JPG - the "blue B" and a bit below a bit to the right: "Through Switch" --- in the schematics (Palooka) they have the symbol for "3-bladed Make-and-Brake-Switch" --- maybe (maybe, maybe) You have stapled TWO Switches - an 2-bladed Normally-Closed-Switch and an 2-bladed Normally-Open-Switch ???

In the schematics I see: Functionality-1 - when a new ball is given: Turn-off the On-Bumper-Relay. Functionality-2 - when a new ball is given: Turn-off the Tilt.

So the Through-SwitchES sit in the Shooter-Alley or the "gate where the new ball enters the playfield" or UNDER the apron - so take away the apron and look. Here: http://www.ipdb.org/showpic.pl?id=1743&picno=1698 - the white metal on the bottom of the pic is the apron.

Please write about the "Through-SwitchES" - have You found an 3-bladed-Switch or an 4-bladed-Switch (means two 2-bladed switches mounted together) ? WHERE is/ are the Through-Switch(es) mounted in the pin ? Greetings Rolf
