The way the joker scoring works involves a combination of the three joker relays in conjunction with a series of score motor switches and the Hole relay (G). The first 1000 points is scored via four score motor switches all closed in series, on the first pulse of motor 1A. Then each of the four score motor switches opens (and then closes) in turn, blocking that path for the other four pulses of motor 1A (the last switch opening blocks the whole path, so nothing is scored on the fifth pulse of motor 1A).

As each motor switch opens though, an alternate 'bypass' path is available via a joker relay switch, as long as the corresponding joker relay has tripped. But if the score motor switch doesn't open, then both the score motor path and the alternate joker relay path is available to score the 1000 points (yielding 2000 points).

So for the white joker relay, this would be a normally closed switch at score motor 3B. Check to see that it's opening, and that the back tabs/wires aren't touching.

Damn thats a smooth ass PF! Where you get that done?

Wow....great job

Well, it was a good theory.

If you block the switch on the white joker relay (2B), and only trip the white joker, then what does it score?

The hole should always score at least 1000, then the white joker should add another 1000, so 2000 total. With the white joker 2B blocked, should still get the 1000 for the hole, so curious if then get an extra 1000, 2000, or zero.

Maroon (the wire color legend is on the lower left side of the schematic).

Is that level B on the score motor though in your picture? (can't quite tell from the zoomed in shot.)

Does this mean that with the switches blocked on the white joker relay it doesn't score the 2000 points, or does it mean it made no difference?

and by this you mean with the white 1000 lit next to the kickout hole, right? The two white jokers are only lit before either of those targets are achieved, which trips the 2B relay (which lights the white 1000 by the kickout hole).

OK, I'll try to be yet more precise. There are actual white jokers that light up near the top of the playfield; a rollover lane and a standup target. Then there's the white insert down by the kickout hole that's worth 1000 when lit.

So when you say "white joker lit", are you literally referring to the lit white jokers (rollover and standup target) at the top of the playfield, or do you really mean that the white insert near the kickout hole is lit? (Only the pair of white jokers, *or* the white insert should be lit, as those lights are controlled by a make/break switch on relay 2B.)

And even more specifically, the white joker relay is relay 2B in the sequence bank, which is the middle relay in the picture you have above. As shown in the picture, that relay is in the "untripped" position. In that position, the two white jokers (rollover and standup target) should both be lit, and the white insert near the kickout hole should not be lit. While 2B is in this untripped position (along with 1B and 3B), the kickout hole only scores 1000 points. Is that correct?

Then when that relay 2B is tripped (and only 2B), instead of getting 1000 for the kickout hole plus 1000 for having achieved the white joker targets (which should now both be not lit), it's getting 3000 total. Is that correct?

And finally, if you block the switches on 2B while it's tripped, do you still get the 3000 points? Or do you only get the 1000 points? This is what I'm mostly trying to understand:

2B not tripped = 1000 points (from kickout hole)
2B tripped, no switches blocked = 3000 points (the problem)
2B tripped, switches blocked = ? points

If it's still giving 3000 points with 2B tripped and all switches blocked, yet only gives 1000 points just by not having 2B tripped, then that suggests maybe the switch blocking is incomplete, or some other physical short is created from tripping 2B.

Another thing to try would be to not trip 2B, but instead jumper closed only the switch that completes the 1000 point scoring path on 2B (SL+GR, OR+GR per the schematic). That *should* cause it to score 1000 + 1000 without having tripped 2B.

The purpose of these experiments is to get a different behavior, to help further isolate where the problem is.

OK, thanks. When you say white joker lit, you are referring to the white insert next to the kickout hole.

I note in the video that while it's scoring 3000, the chime only seems to be dinging twice (so the score reel is faster than the chime plunger perhaps). That suggests that the extra pulse is getting in during one regular pulse.

In your schematic picture above, where you have the normally open switch on 2B circled in white, with the arrow pointing to it, that's the switch to focus on.

When 2B is not tripped, the behavior is correct.

When 2B is tripped, the behavior is getting the extra points.

If you block that switch circled in white on 2B, the behavior should be the same as if 2B is not tripped at all. That switch has a Slate+Green wire on one side and an Orange+Green wire on the other. That's the only switch that is involved on 2B, so it's super important to identify that switch. Blocking that one switch should match the behavior as if the relay wasn't tripped.

Once that switch is identified, check the contact points on the blades of the switch and see if either one is loose and able to spin.

Good. So now that confirms that the switch on 2B is a place to focus. When 2B is not tripped, the extra 1000 points doesn't happen, so there's not a stray short anyplace else. And when 2B is tripped, but that switch is blocked, there's still not the extra 1000 points (or any points) for the white joker.

To me, this suggests that the switch on 2B is 'bouncing' the signal somehow, and letting two scoring pulses through (the chime sound on the video matches that too).

he contacts may just need cleaning and the switch gapped a bit closer to get a tighter close when it trips though, so could try that. Or, could try to jumper that switch closed, rather than block it, to see if it can eliminate a bounce.

Yes.

So when the first 1000 is scored, that's via the path: Motor 1A+Motor 4C+Motor 1B+Motor 3B+Motor 2C+G.

But when 2B is tripped, the path bypasses Motor 3B, and goes: Motor 1A+Motor 4C+Motor 1B+[G+relay 2B+G]+Motor 2C+G. Note that there are actually two separate switches on G that are involved (before and after the relay 2B switch, logically).

This path should also only score 1000, but of course is scoring 2000 instead. Based on the chime only firing once, it suggests that there's a jitter in that one pulse somewhere.

In theory, if the motor 3B switch is blocked, then the initial 1000 points should not score, and only the (incorrect) 2000 points should score (when relay 2B is tripped).

Further, if you jumper the motor 3B switch closed, that should effectively override the bypass path via [G+relay 2B+G], and only score the initial 1000, plus 1000 when 2B is tripped (or untripped - shouldn't matter). I think this is probably the next best test. If the scoring then works correctly, that isolates the jitter to specifically that [G+relay 2B+G] path, and some additional jumper tests can be done for further isolate.

So jumper that motor 3B switch closed, and see what the scoring is when relay 2B is tripped and the hole is activated (can just activate the G relay directly if you want).

These are very curious results. Jumping 3B closed should simulate what the behavior is when 2B is tripped (and it does; it scores the 2000 points as expected). But it also should have overridden any jitter if there was any in the path via 2B tripped (since 3B jumpered provides a continuous signal still).

So I think this suggests that the extra signal isn't specifically coming from that G+2B+G portion after all, but apparently is only happening when 2B is tripped, so the signal is getting through there.

Not exactly sure where to poke next, so some things to try to see how the results change (if at all):

- Block the motor 2C switch. This should prevent the initial 1000 being score, as well as the 3000 when 2B is tripped (so basically nothing should score, with 2B tripped or not). If it does score when 2B is tripped, then that suggests maybe there's an issue with relay 3B switch.

- Block the D switch (the path the leads off below this section on the schematic). Shouldn't be involved, but just eliminating the possibility.

Also, on the score motor, the switch stacks sometimes can tip a bit and run into an adjacent bracket, creating shorts. Might be worth checking that the switches are level, and not touching anything adjacent.

so sorry to join in so late in the game. here is something that gets overlooked. the 3 stand up joker targets are a 3 blade make/make switch. sometimes if the target was moved from liberal to conservative , the back 2 blades will be closed maybe from the rubber. remove the plastics from these targets and check switch gaps. if these back 2 blades are closed on any of the stand up joker targets , all kinds of crazy scorings will occur.

These are good data points. These indicate that the extra scoring isn't "leaking" from anywhere else, which leads back to just that G+2B+G bypass path when 2B is tripped. The extra 1000 has to be coming from there.

So, this is where it's going to get a bit complicated with the jumpering. Previously, you jumpered directly at motor 3B, but now the goal is to narrow that bypass path further by jumpering increasingly smaller segments of it. So instead of jumpering at motor 3B, a first next one to test would be to jumper on the "far" sides of those two switches on G. That should jumper over the entire bypass path.

Then there are two segments in that path: the first G switch to 2B, then from 2B to G. Each can be jumpered. So for example, can jumper from the first G switch to relay 2B. But both the 'far' and 'near' sides of the switches can be used. One quick shortcut test is to jumper from the 'inner' switch on the first G switch to the other 'inner' switch on the second G switch. This jumpers over the relay 2B switch, but leaves both G switches in operation. It's like jumpering the relay 2B switch directly, but the test points are away from the actual relay 2B switch, so more of the wiring path is included.

The goal with these different test points is to find the narrowest combination that only scores the 1000 instead of the 2000. That further isolates where the jitter is entering.

'Near', 'Far', 'Inner' are all in reference to their position on the schematic in relation to the relay 2B switch.

Yes, those are correct.

The red line test should score 1000 regardless if 2B is tripped or not, as should the blue line test.

The other two rests will require 2B be tripped.

The results should be interesting (hopefully).

That seems right.

The '+' and '-' designations are explained on the schematic in the lower left side (along with the color abbreviations).

Those look original to me, so not sure that's such a good idea.

Before attempting to mess with all those switches, I'd suggest trying the other jumper tests first.

It's probably easiest to unsolder/re-solder the wires. Swapping the blades requires dismantling the stack, and also getting it back into the Nylon ladder.

Might want to also check that 1B and 3B work correctly though too, and that the problem doesn't just move.
