One more issue with my Daffie I'm getting around to and hope someone can help. It is not awarding extra balls when I reach high score thresholds set by the plugs. I have tried multiple high score settings and nothing seems to work. The plugs are clean and fully in their slots.

The game is set to regular/AAB play and DOES award specials for other plug-set awards like gate, automatic X, and bottom lane X.

Any idea how to track this down? I'm not sure how to interpret the schematics in this case. Does anything look off in these pics?

Thank you!

Thanks, Mark, much appreciated.

I checked the Reset Relay, specifically the G/O wire in the MOB switch in that stack - it is normally closed in the MOB and opens properly when the coil fires. I cleaned all the switches with a flexstone for good measure.

Getting to the 10,000 drum unit EOS switch is a challenge - looks like I will have to remove the whole score reel assembly to get a look and a hand in there? Am I reading the schematic correctly, that the 10,000 EOS should be normally open?

One other odd thing I noticed - the 10,000 drum top contact panel that receives the wires from the High Score Adj Jack has the Grey-Red wire in the middle of the High Score wires (between White and Brown) rather than on the end as the schematic seems to indicate. Is this typical?

Thanks again!

I was able to adjust the EOS switch so that it closes when I manually activate the score reel (confirmed with multimeter clipped to both lugs of the EOS, buzzed when the score reel is activated).

I then confirmed continuity all the way from the Green/Orange lug in the Reset Relay (closed normally) to the grey/white jones plug (unplugged) - buzzed when the score reel is activated).

I then plugged in the plug to the 20,000 (red wire) jones slot and confirmed continuity to the red lug on the top of the 10,000 panel as well.

I figured the EOS adjustment would solve it, but it has not. I am still not able to get added balls when hitting the score thresholds. Where do I go from here?

Thank you. I tested continuity between the common solder bulb and the red solder bulb on the top of the 10,000 drum unit with the reel set at 2 and there is no buzz (I also tested other reel locations with common/red just in case, as well as blue with 3, etc. - same result). Prior to testing, I started a new game and then turned off power, with all reels set to 0.

Am I accurate that this combination should produce continuity, and lack of it indicates an issue with the adjustment or contact of the finger inside the 10,000 drum unit? If so, I'd appreciate any resources on disassembling this type of score reel to investigate.

Problem solved. Turned out the wiper contact was not making a connection to the board traces all around. Disassembled, cleaned, adjusted the wiper, and got it back together and scoring extra balls on the score thresholds perfectly now. Thanks for your help in getting me going.
