Hi everyone

Pinball newb here with little experience working on these but trying to learn. I definitely do better with hands on than schematics but I try.

From unplugged state:

1.plug in (nothing)

2.add quarter

-playfield and head unit lights turn on
-game adds credits correctly
-motor turns
-ball kicks out ready to plunge

•
All score reels fail to reset •
•

Playfield is active and all score reels will accumulate points correctly except for the ones reel.

The ones reel will mostly spark and make a buzzing sound when bumpers or targets are hit but will %90 of the time not advance. Ones reel can be advanced manually with finger and moves easily. Tapping ones relay will also add points to ones reel but bright sparks occur when tapped. Sometimes the relay holds shut and blows the fuse both when manually tapping or via playfield

Ones reel will NOT advance tens reel when rolled past 9.

I hope i explained that correctly. I guess the thing to do is to get the reset working properly.

Thanks for reading.

Ok, I just noticed something else

1. The previous owner has been soldering connections on the score units specifically on the end of stroke connectors

2. The tens reel end of stroke switch is broken off.

Thanks Bill

Would a broken EOS switch effect the reset? I actually have the original schematics that came with this machine. They are old but still legible!

Guess I’ll order that EOS now. I kinda wonder if I should just order some other parts while I’m at it just so I don’t have to make multiple orders.

Right. So where do I look to fix the reset?

Thanks

They don’t spin at all when you start the game. It doesn’t even sound like they are trying to reset. So if the score reads 2222 when you put a quarter in it just stays at 2222. From that point you can play a game and add to that score.

Thanks for the link!

After reading the above link i cleaned some connectors, repaired a leaf switch on a score reel and soldered some suspicious wires. I can now get the machine to reset correctly and the field is ready for play! Thanks!!

Remaining issues

1.When the ball in play drains the credits won’t go down. The credits reel DOES act correctly when adding a quarter and starting a game.

2.Ones reel will not advance. Just bright sparks from the relay, all 4 lead switches flash brightly. It’s not the reel itself as I have removed the number reel and moving parts from the equation. The coil shakes but will not fire properly even with nothing in its way. If I remove the tension spring the coil will fire. Video below
