Picked up this beauty a couple hours north of me. My 16 year old son and I are in the process of cleaning, replacing, and learning about the relays, solenoids, contacts, motors and everything else. Power button brings up playfield lights. Game reset button brings scoring wheel to zero, but does not advance the credit wheel on the back glass. Furthermore, the score reset relay in the upper cabinet is clicking away without stopping. We have to power off before it drives us crazy. I'm wondering if I manually change the scoring wheel to see if the problem persists.

Here's the chatterbox relay. The wheels do reset to all zeroes, so I'll keep looking around. This is where a local expert would help out in a hands-on tutorial.

Newest problem (on top of the others) is the playfield lights don't come on when switch is turned on. All fuses were checked (out of the machine) and fuse holders are not cracked, worn, corroded, or have broken wires.

I found 5 total fuses.

Fred, you are the man. A solder joint at the green/yellow/white wire to fuse had sheared off. Couldn't tell it was bad until I tried a jiggle. At least one thing has been fixed. I'm thinking the stepper relays may be the culprits for start up problems.

Update: I took most of the Credit Reel apart, cleaned and polished the steel plungers, cleaned the plunger cylinders, reassembled everything AND the Credit Reel steps down!!!!

I reinspected the score reels and made one leaf contact adjustment on the 10,000 reel AND the coin door is not energized, the motor stops running after the reels are at zero, and the Score Reset Relay is not energized any more.

Next up: clean the Ball Count assembly in the upper cabinet. Maybe then it will be ready to kick out a ball and I can play some pin action.
