I never use sandpaper on the contacts. I’ve always used a wire wheel on a Dremel tool. It cleans the contacts great without filing them down!

Ok finally getting to look at my machine. When I power it on absolutely nothing happens other than the coils in the pop bumpers quickly energize.

If I press the start button the GI lights (only) come on, no insert or pop lights. The cam just continuously spins. I made sure the cam closest to the motor was positioned so it sits in one of the 2 notches.

I have no lights in the back box at all.

Also, anyone have schematics for this game that can advise as to what fuses go to what?

Thank you!

Verified all fuses are good but the below issues still persist. Where to start?

Messing with game. Took out the board in lower cabinet and inspected all the switches. Found 1 on Lock Relay that wasn’t gapped properly and few others that looked as though they weren’t making great contact.

Turned game on and right away the coil on the coin door coil and pop bumper coils engage briefly (fire once) and the Cams

At this point no lights are on or anything for that matter. When I press start the cams continuously rotate, the coin door coil fires on n off and the Score Reset Relay pulsates.

Player 1 resets to zero but not Player 2.

Also, if I press start button second time the pop bumpers engage and don’t release.

Several issues going on here.

Thanks Howard, always appreciate your willingness to help out. Hope to get time Sunday to work on it. Will report back!

Forgot to mention, and obviously, after a few seconds of the pops engaging the 15A fuse blows (second to last from the bottom of the tower of four fuses).

So it’s Sunday and I worked on the machine a little. I spent all my time cleaning and properly gapping all the switched in the bottom of the cabinet and also all the switches under the playfield on the board.

I then started to clean and gap the switches on Player 2 and that’s where I stopped.

More to come ….

Slow going here but got a few to clean and gap more switches.

Found the pops firing odd as all of them where. When I cleaned the pf I replaced all the skirts. Come to find that, either the new skirts are longer or the others were worn as all the switches were closed.

Upon powering machine up the pops no longer fire and the cam moves a notch. No lights on the machine at this time.

Upon pressing start button the GI lights, including back box, come on. Cam spins continuously, player 1 and 2 scores reset with the exception of the 10k and 100-900 Units on Player 2 and the Score Reset Relay continuously fires.

Haven’t used jumper wire as of yet. Never done it this not really sure what and where to jump on this machine but will read the links Howard provided to try n figure out.

Just want to provide what iam doing and finding so I don’t forget and to keep this post active.

Thanks!!

The reels move freely by hand. I actually took them both apart and cleaned them and ensured the switches are gapped. I did this today and same result.

So scores reset with the exception of the 10k and 100-900 Units on Player 2 and the Score Reset Relay continuously fires???

Yes

It does not score. It appears the assembly that runs the coils for the puck in the backglass is holding it up. The coils are firing but not advancing the puck.

I took this assembly completely apart and cleaned it to no avail. It works sometimes. Any advise on this assembly?

Thinking needing to look more at switches.

Wanted to follow up on this. I did as you instructed and player 2 still doesn’t score if I manually pulse the relays.

Welcome any more insight BUT know that I am now back out in CA so I won’t get to work on the machine unti I head back East.

Thanks for all the input.
