Tim and Mike, thanks for chiming in. There is no circuit board on the 1k reel. This game only has circuit boards on the 10s and 10k reel-obviously, the 10s is for the match. So yes, you can only set replays at the exact amount-example, the recommended high score settings for five ball are 130k 180k and 190k. It's different from any Gottlieb I've ever worked on, in that the high score plugs are designated as 1 and 0. There are 3 plugs on the 1 chain and 2 on the 0 chain. The 0 is used for high score replays under 100k and the 1 set is used for high score replays above 100k. On the 10k reel, in place of the EOS switch there are two normally open switches. One of those is the switch that is in the circuit to the replay unit step up coil. The game uses a 100k relay that has a normally open switch that lights the 100k light on the backglass, and a make/break that changes state at 100k points and is the conduit for the replay circuit when scores are either above or below that threshold.
I've tried moving the high score plugs to different settings and it really makes no difference. I will say they feel a bit loose in the socket, they go in very easily and that feels kind of weird to me but I'm not really sure how to tighten those up in a Gottlieb jones plug setup. I have not pulled off the jones plug for the high score settings yet, I guess that's another place I can check.
All of the solder joints on the circuit board look original. I checked to make sure the common wire was good, that for some reason breaks off fairly easily (it was broken off on the 10s reel) and all of the wires on the circuit board are solid. I cleaned the circuit board and bent the wipers up to where they were actually dragging the reel a touch so I know they're making good contact. I cleaned and adjusted those two switches on the 10k reel and they are making good contact, the blades are bending enough that I know they're making. When it works, I can see a small spark at the switch on the reel, so I know power is getting there but somewhere in the circuit it's getting interrupted. I have to take the reel out of the holder to manually step it, and I almost thought it acted like there was a broken wire, like a broken wire inside the insulation, which I guess is possible but with stranded wire not really likely.
The circuit really isn't that complex, it goes through that switch on the 10k reel, through the JX (100k) relay make/break switch, through the circuit board, to the step up coil on the replay unit. As I said, it works perfectly for the drop target special, although that's a different circuit, but that is telling me that the replay unit is working correctly and the max credit switch is closed, which is a common culprit when a game won't add credits.
I tried jumpering around this but I'm not sure I got the jumper in the right place. Maybe someone with a schematic can tell me where to go. I tried going from the 100k replay switch to the same color wire on the 10k reel switch and that did nothing.
Really frustrating.
