Quoted from lpgnr:

Thanks. I see no issues with my switches when I lift the play field.

No black wire hanging loose by any of them ? Especially the upper playfield one ?

Then check connector J601-1 to be sure it is plugged onto the I/O board in the backbox. That is the longest board back there with all the fuses on it.

LTG : )

#8752 7 months ago
Quoted from zaphX:

It looks like they are all on the same connector - first thing I'd do is check in the backbox and make sure that connector J601 is well seated.

Thanks. I reseated the connector, and the bad switches still come up.

None. No loose black wire on any of them. Do you have any other thoughts or possibilities? I really appreciate your help!

Next you'd need a meter to check continuity of the wires from the EOS switches to J601. You have a broken wire somewhere.

Did you check the EOS wiring on the upper flipper ?

While switch test mode is on the screen, if you manually close any of the flipper EOS switches with your finger, does it trigger on screen?

Excellent.
You've already grown some in your pinball experience.
In the future this may at least help things seem less intimidating if they pop up.

Agreed. The best way of learning is by doing . . . Although I don’t want to further break my expensive game, if it can be avoided

Understood. If you have a tech of knowledgeable friend to help you. Don't get in their way. But spectate and ask a few questions.

You'll be fine.

#8761 7 months ago
Quoted from lpgnr:

It does not.

Please try again. Tests - Switches - Dedicated - move each flipper bat back and forth. See if any, especially the upper playfield ones, register on the screen.

Thank you.

#8762 7 months ago
Quoted from lpgnr:

It does not.

I don't know what visibility is like, but see if there's a loose black wire at the upper playfield flipper EOS switch. That upper flipper EOS registers okay, but it's the only one. Maybe the break is after that point and is preventing the other 3 from working.

#8763 7 months ago

Should this wire be connected? I wonder if this is the culprit . . .

Quoted from mbrave77:

Whats the best way to get up the left ramp all the way? I dont feel like the backhand will get it up there often, and coming from the right flipper its very dangerous. I just had my first real good game 5.8m and 3 of my drains were trying to go up that left ramp.... I am plus 1 on each of my bottom flippers.
thanks!

I backhand that ramp all day. I’ll even post pass from the right flipper to get it over to the left.

Bump up your flipper strength by 2.

No, it is right above it. There are two black wires above your circle, and the upper one is not attached. This is for the upper flipper.

Just the left? Or are you plus 2 on both?

I'll get you a picture shortly. It probably is your issue. I just want to be sure where it goes.

I think I’m plus 2 on all 3 lower flippers. I can double check tomorrow.

Not sure if you can see it good. Two black wires to the top lug of the EOS switch.

That’s it! I have one wire just floating there. I just have to solder back onto the top lug to fix it, correct? That should take care of the bad switch tests?

#8773 7 months ago
Quoted from fooflighter:

I'm in the same boat. The Appetite stand up is deadly. I watched a little of IE pinballs stream and he was going up with the right flipper...he did note that he lowered his flippers slightly from factory (flopped)...similar to Jurassic Park I'm assuming for making those side shots easier...I'm just gonna keep practicing but there is a definite narrow window of opportunity on that right flipper to not hit the dreaded Appetite standup and drain immediately versus going successfully up the ramp. I try to backhand it like the Death Star Ramp but it's really tough to time it perfect, you can do it if you hit it on the roll or a fast slap save...
It's a good challenge. I remember when the helicopter shot on JP was was nemesis..now I can hit that shot all day
I'd say the 3 hardest shots on GnR are : 1. Under the flipper - crowd 2. Left Ramp without draining 3. Left and right orbits when your panic flipping during a song

Well put

#8774 7 months ago
Quoted from lpgnr:

Yes.

Quoted from lpgnr:

Yes. They will clear during game play or if you check them in tests after you solder the wire on.

Since you might be new to this. Be sure your turn the game off to solder on the wire.

Definitely looks like a wire broke off where the green arrow is pointing.

Excellent! I am going to call my father-in-law, who is an expert at soldering, to take this across the finish line. We’ll make sure the game is off

Thanks again so much for all of your help!

With the benefit of closeup, color correction, and shadow reduction, I think it's just a spiral in the wire you circled. I thought it was solder initially, too.

Quoted from lpgnr:

This is in the upper playfield flipper, right? That's why it was the first and last working EOS in the chain.

Yes, upper playfield flipper, and it was a spiral (not the best picture). That is good to know.

I put the flippers inline with the lane guides, not flopped, and I did it because I wanted to stop the backhand left ramp shot and to give more power to the orbit shots. Overall the shots simply feel better to me this way.

This.
If you can backhand the left ramp you can really exploit the patch rules. Especially when the ramp diverter is up or on the SE where the ramp returns to the slower inlane allowing you to trap it on the left flipper. Rinse + repeat.

I stand corrected, I misunderstood. Mine came from the factory as yours are setup now so I thought you changed them to something else...my bad... It was fascinating watching you play this game. In the vid you said you only had it a week, I was amazed at that ability to call shots, stream, instruct and still blow things up. First time I saw your vid...definitely will be watching more...but I had to look away as I don't want to spoil too much right now...but just some of the initial hints you were giving about what does what and why...for example the left diverter raising and lowering and why...I couldn't figure it out and after you pointed it out...makes total sense.

Quoted from zaphX:

Maybe something stuck in the switch? I think someone found a screw in there once. Maybe the switch needs a little bend to ride lower?
Here's a naked pic if it helps diagnose. I think I'd poke a magnet around where the wire switch is first. (check it from below too)
[quoted image]

That is correct. I found a screw wedged in the switch slot on my machine which locked up a ball regularly there. Removed said screw and never happened again after that.

Funny enough a few years ago when I first came across LTG, I thought it was some pinball or real life abbreviation, like LMAO. So I googled and got the result LEARN TO GOOGLE. I thought That wasn’t a very nice way to help someone out here lol.

#8794 7 months ago

Just a thought I'm sharing to see what others think... I suspect over time, the drop from the upper playfield to the hole under the upper flipper may start to dent the wood. What about putting one of these Silicone Rubber Bumpers over the mylar to prevent (Maybe even cut at a slight angle). Is it overkill or potentially useful?

Beta 7 released today has more focus on keeping coils cool.

Quoted from kermit24:

Ha! I've actually stopped exploiting the unlimited booster multiballs via the AMP lane. Those patches are very low on my priority list these days. Keeps the game more interesting only having one shot at them before each song.

Fixed bug that could keep spotlights moving after encore.... Hmmm. Possible source of broken spotlights? Over utilization could at least be a contributor to speed up failure even if it's not the true root cause.

Near as I can tell the servos are just a wear item and the occasional bad part happens.
It does not seem to be specific to our use case; I saw a YouTube video of a guy whose model airplane crashed because a servo seized up.

I replaced the left vertical one myself, the servos are available at hobby shops and are cheap.
You do need to be careful to attach the arm with the servo and spotlight both in the center position.

I used this successfully:

Interesting and really good to know, I thought I read back in this thread that the engineers at JJP were sending out full assemblies instead of parts for the spotlights because they needed to be calibrated, have you found anything out of sync after centering them up post repair? Is the reason for centering them for this purpose or is it to prevent the arms from breaking. This would dfinitely be handy down the road

#8800 7 months ago

Well, I received LE #745 just over a week ago and have been busy playing non-stop!

Only issues thus far:
- A screw fell out of the upper playfield (top-most, left side) clear plastic mounted to two posts (took me over an hour before I finally found this bastard!)

- Last night I noticed my upper playfield and upper right flippers seem to only be working 70% of the time. Need to figure this out now. I've checked the wires that connect and they all seem securely soldered where they should be. All backbone connections are secure as well. Of course I checked just the ones that are plugged in... does someone have a picture of what the J601-1 connections look like in the backbox?
