I recently picked up a Bally Happy Tour (the add-a-ball version of Grand Tour) that was really, really dirty (https://pinside.com/pinball/forum/topic/another-rare-zale-era-bally-joins-my-collection) and has cleaned up quite nicely, and generally speaking, it plays really well.... except the pop bumpers are not scoring. They trigger just fine, but no score is added. I've looked at this schematic, and I'm just not seeing a pathway for how these pops are supposed to score. Link goes to a schematic for Grand Tour, but this part should be the same... I've compared the schematics (I only have a paper copy of Happy Tour) and the only differences I find relate to replays vs. extra balls.

I'd welcome any ideas the hivemind has about this one.

Here's the section in question. I'm not seeing what you're talking about. The thumper control works correctly, turning the lights on and off, but does not score-- if I'm understanding you correctly, for one (the lights) to happen, the other should happen as well, no?

It does. That unit has been cleaned, and appears to be working correctly. Additionally (like Hay Ride) each of the pops has it's own set of switches and relay on the underside of the playfield. They have been cleaned, gapped, and tested with the multimeter. If it were only one of the pops doing this, I would concentrate more effort on that... but since all three are doing exactly the same thing, I suspect the problem is elsewhere.

I'll take a picture of that when I get home tonight.

No score at all from the pops. The slings score correctly.

I will. But if that wasn't working, it looks like the slings shouldn't score either... and they score fine.

Pics of the thumper unit are attached. While I was working on it, I cleaned everything again- this unit, the switches on the underside of the pops, and the thumper control switches on the bottom of the playfield.

After tinkering, the pops now score ones (when unlit) but do not score tens (when lit). Don’t know what I did to fix that, but some progress is better than no progress.

I've tinkered with this some more, but made no more progress towards the pops scoring 10 when lit... as noted above, I now have it scoring correctly when unlit (1 point), but it doesn't score at all when lit (10 points).

Open to any ideas you guys might have. Game otherwise plays flawlessly and is in great shape... so I'm highly motivated to figure this one out.

Mein Deutsch ist schrecklich. Mein Großvater wäre enttäuscht. Ich habe einen Schaltplan, sehe aber nicht, wo die 1-10-Verschiebung stattfindet.

Now I've got it scoring 10's but not 1's. LOL. May be time to pull the bottom board for closer inspection.

This is resolved. I went through and cleaned every switch for a 3rd time. I didn't adjust anything... and it's working.

Now to deal with that sticky 100's score reel (luckily, no mystery to solve with that one!).
