Hi pbm3
I would like to help - I do not know the pin - I look at ipdb-pictures, manual and schematics. First I ask some questions so I really understand the pin.

Here http://www.ipdb.org/showpic.pl?id=1709&picno=10276 I see 10 rollover buttons in an arc - the rightmost button is lit - below is one of the arrows lit to tell us in what direction the light below the buttons will step. This http://www.ipdb.org/showpic.pl?id=1709&picno=30772 is the area below the playfield. Here http://www.ipdb.org/showpic.pl?id=1709&picno=18916 I see the puck set a bit to the right. Here http://www.ipdb.org/showpic.pl?id=1709&picno=30763 we see it in the backbox.

Question-1: Do playfield-light(s) and Backbox-puck step synchronous - means there are two sighs to inform the player about ONE fact ? (((Or does playfield-light step - but Backbox does not step etc. - means there are two independent / different features ?

Question-2: The goodie in Your pin / Backbox - has it a papertag - what is written on the tag ? Maybe "Advance Unit" ? or what ?

Question-3: The stepping on "Advance-Unit" - does it usually step just ONE step ? - seldom 3 steps ? When a new game starts: Stepping as many steps needed to reach "middle position" ?
Different numbers in stepping ?
In a One-Player-Game: always stepping to the left (respectively always to the right) ? After a goal has been made: The pinball-machine does automatically reset to middle-position ?
In a Two-Player-Game the logic of stepping is ?
When a ball is lost: Does the machine reset the Advance-Unit to "middle position" for next player / next ball ? You see - I do not understand the logic in this unit ...

Question-4: Do You have 1 - better 2 jumper-wires ? You then can manipulate - forcing a good / guaranteed connection (through jumper-wire(s) - the long jumper-wires are clipped-on where we mus clip-on - but the jumper-wires are long - so You can stand at the backbox watching the unit - making contact as You hold the free ends of the two jumper-wires together.

Question-5: Does the description in post-1 means "stepping is good - but when making a goal: RESET is no good" ? Greetings Rolf

I just picked up two of these today. Here's a note I read on the Internet Pinball Machine database under reveiwer's comments:

Nice game fun to play and dependable. Clean lube & tighten springs on the puck unit for reset problems.
Art : 7 / 10

Good luck with yours. I will be restoring mine in the summer, hopefully

A few fun and fast 2 player game, very complex and picky when it comes to adjustments IMHO!!

Make sure the puck mech board is centered correctly (there is 2 screws to allow rotation) and contacts clean and the player ball unit was a trouble spot on mine too. Reliable now but took some doing to get it there.

Anyone have a decent backglass for sale? Mine is in tatters.

I got a quote from this place but, they are not silk screened and are not cheap. $245 plus shipping. I will probably get one, and attempt to the restore the one I have ( I have two machines).

Good luck!

Under the reel the puck tape is on. You can remove the 7/16's nut to take reel off and loosen the 2 screws. Sometimes you can just grab the PCB and tweak it one direction or the other.

When in the center position the "first" light should be lit on the playfield indicator rollovers. Some times tweaking back and forth will be required.

I'm aware and have been in contact with them, can't justify spending that on a slightly beat up and well worn pin at this time.

No, there is two screws on the top, under the reel. Taking the reel off is the only way to access them. Loosening them will allow you to rotate the PCB disc left to right to center the unit.

Note that centering the puck on the backglass and centering the unit electrically are two separate adjustments. Do electrically first, then worry about the puck after.

Not sure if this one is better than yours but you can have it for free if local or you pay pack/ship

This is from a parts machine so if you need other items let me know

Thanks

Appreciate the offer, looks more or less the same condition as the one I have though.

Check to make sure there is no broken wire to the puck unit or a bent/dirty finger contact.

I had a similar issue but mine won't reset more than 2-3 steps after a goal on player 1, player 2 is perfect. Sounds like you got yours working nicely - mine is still stuck in incorrect operation purgatory.

RacingPin If you've got the goal PCB and the reel unit with the spring loaded contacts I might take you up on that. The connections at/on the PCB seems to be my issue.

gdonovan & Heatbag my backglass was the one used for the BGresto repo. It turned out pretty nice but being picky, there are a few little issues mostly around the mask/blackout layer. There's lots of extra light shining through around the score wheels, Ball in Play count, and the match numbers. I'd be happy to try to scan you a copy of the front art. The problem with the mask layer is it's baked behind a black layer of paint so not much to offer to help recreate a real translite.

@steviechs: Here are the unique items I found in the parts machine head.

I have this same machine and cleaned, fixed and adjusted it and have it working pretty well but with one issue.

I get intermittent Advance (top rollovers, side roll overs, lower rollovers and center pop bumper) to goal on player 1. Player 2 advances without an issue. If I just play 1-player games eventually it seems to fix itself until I go to a 2 player game again.

I have cleaned and adjusted the Player Relay and Transfer Relay but still have the intermittent problem with Player 1.

Any suggestions?

If the wire colors at schematic F12 for Left Advance coil and Right Advance coil are correct for what's not working, and your advance to goal unit is working mechanically, what's the Transfer relay doing when your game is malfunctioning?

Is there any chance you still have the advance unit shown in IMG_1757? I have this machine and one of the ratchet stops just broke off from metal fatigue.

Thanks!!!

I have this machine and everything works except the buzzer does not sound when a goal is scored. The buzzer is there, but no sound.

Adjust the buzzer to soft instead of loud. See if it will work with that setting. One of ours doesn't work on loud, but does on soft.
-Paul

If it doesn't buzz when set to soft, Inspect and diagnose this circuit with Alligator clip jumper wires
If it buzzes when set to soft and you want it to buzz when set to loud, replace the diode.

Which switch was it? That condition of no goal scoring, then pucks resets to center when no 10 button is hit.
