Hi guys! I'm new to the club. Recntly bought a Rr75Oz with 2.0 light boards. Love it so far, but it's really hard! Moved in the NPLH outline pin, but gee. Have it at 7 degree. Saw some people suggested 6.5. Any thoughts? Also, I might need to adjust the balloon to be more responsive. Seems to not bounce a lot. The munchkin ball lock also seems to let a third unlocked ball to blast two locked balls out. Read the thread up to page 12 so far. The height of my ball lock arm seems to be the recommended 1/4" and kisses a block inserted. I played with the timing and extended ball 2 and 3 to 250ms. Feels like if there were a strong down force (eg a spring to pull the arm down) it would help. Should I live with the occasional 2 ball fake "multiball" or go crazy adjusting. Have spent hours already. Thanks in advance. Wonder why JJP doesn't revise it if everyone's does this? (Plan to read the whole thread but i read slowly). So far I've added the pingraffix blades, 3D doors, the castle lantern, the castle flipper topper from and Sparkle green city from Back Alley Creations, Wizard fire pots from Mezel Mods, some white trough lights from lermods (added a 90 degree piece mine to the underside of the bottom arch so the light goes over the flippers), also getting the firey witch, flickering balloon, and corn row from pinball mod Co. Would love the Gouiva flying monkey if anyone knows of one. I also added several hallmark items including Glinda, munchkin mayor, coroner and Winkie guard loin scarecrow and tin man.

Thanks. That makes sense. I figured it out. The spring was not on the arm. I found it in the con box and reinstalled it. Now it works well. Thanks all.

I have 2 questions. The other day, I turned on WOZ and instead of booting, it came to a text menu with 2 choices. The default was Ubuntu, and I forget the second, but it was saying to use the keyboard to make selection. There was a 15 second countdown timer. After waiting out the 15, it booted fine and hasn't done it again. Does this mean anything? Why did it happen?

My other question is in regard to the spot light 2 pin molex connectors. Does anyone know which size the pins are? I have some m/f crimp connectors for a standard "PC 5.25" floppy drive" connector, but they were a smaller gauge than fits in the JJP spot light connector. I want to buy the right thing.

Thanks in advance

I think the connectors are 0.93?

The next few times it booted fine, but I've changed the battery using the instructions from section E in the willy wonka manual available on Jersey Jack Pinball's site. Thank you for your help. The one in there was a no name, so assuming it was original.

I'm sick. My RR75WOZ Backglass slipped and broke. Does anyone know where I can get one?

That's awesome. I hope so. Do i call JJP?

Thank you. Martha was great and is helping my WOZ get back on her feet!

I'm not an expert and when all you have is a hammer, everything looks like a nail... that being said, if it's the case that your problem vanished when the playfield was out of the cabinet, then maybe it's kinda related to the skill shot problem. Let me say that my skill shot went crazy. I didn't know why. You couldn't see through the coin door that it was touching the ground/ playfield slide bracket. In my case since the skill shot was affected, I covered the back of the skill shot with electrical tape and it solved the issue.

My concern is that something is grounding and seems to happen when the playfield is in or possibly jostled. It could be anything I guess, but gee. It would cost less than $1 to temporarily cover the metal slides and ground wire with electrical tape and reinstall the pf. See if your problem goes away. If it does, then you could selectively remove pieces until your problem recurs. Then investigate that area more closely?

Hi, I'm having a problem with my RR75WOZ. Randomly but several times within a 5 ball game, my castle doors open by themselves and you see the vuk try to plunge out a ball that's not there. The screen and music go to the "Rescue" mode. It may do it many times in a row, or just once. ( eg doors open, vuk ejects nothing, doors close, doors open, vuk ejects nothing, etc) I first tried shaking the game to see if there was any correlation, but there wasn't. I read the issues that another guy was having recently and tried unplugging my in game usb hub with Bluetooth and wifi dongles. Was REALLY hoping this would solve it, but it didn't. I also attempted to "clean the opto" thinking it might have to do with that vuk. I'm not sure I did this well or well enough. I put 91% alcohol on a q tip and "tried" to stick that into the vuk to the left and right. Couldn't really tell if it was cleaning anything. I also went into the switch test, and when this happens, the two door switches are lighting green. Any suggestions to troubleshoot this? Thank you!

Any thoughts on this? Thank you.

I'm also interested. Want to see the details though.
Looks like you had to move the castle walls?

Thank you! I will check that!
Full disclosure, when I installed the Pinball Mod Co awesome firey witch months ago, one of the two nuts that held the "witch tube" onto the metal base flew under my castle pf and has never "shaken free. " so I'm a bit concerned is wedged in there somewhere (over the rainbow... lol). I have on order full Cliffy set for WOZ, so I knew pulling all the mini pfs was in my future. It probably won't be here til Thanksgiving earliest though. So not sure if I should a) pull castle twice to fix this and later for Cliffy, B) don't play till Cliffy comes then do it all at once c) ignore the doors till Cliffys arrive.

Fwiw, in reading the complete thread but have been dying for months and today got to page 40 of 286!

If you now have the "broken" switch in your hands, you could test it for continuity Again with the dmm. If it shows that it's now actually faulty, then you could make the assumption that testing it "in circuit " wasn't accurate?

The side rail of Medeival Madness SE (remake) also has the "two screws" visible along the rail, one in front that has a stud head with a nut on the inside, and a similar one in the back hidden by the head hinges. My Woz75RR has no visible screws on the rail.

The battery is in the metal box on the PC motherboard.

I have a RR75th anniversary and I've tuned the spinning house perfectly in the Test Menu, but during gameplay it always uses different settings and only opens 1/2 way. I'm on Ver RR7.04. Is there some other place where I need to set the values or is this a bug? Thanks.

Exactly! Lol. The settings for my machine are spin =7 and open force =14 but the game clearly does not spin it to 7. It does less than 7, and so the "leg door" only opens 1/2 way. But in test mode with 7/14 perfect every time. Very frustrating. No one else notices this?

So turn the power off and put the house where it is when I run the test and when I turn it on it will just work? Or set the house randomly then turn it on? Then do I try the test over and get new values? I want to do this but not sure what you mean. Thank you for the info.

Well, I rotated the house to where it "should" be to open properly with it off and then turned it on. The test at 7/14 worked perfectly as usual. With glass off I shot a ball, caught it, spelled rainbow with my fingers and threw the ball up the ramp for twister. Let the ball go around the house the prescribed number of times and it opened the same as always. The house needs to be a bit more counter clockwise. So i went into the adjustment and set it to 11/14 (4 more counter clockwise). The test now makes the popper rod hit the front of the house. Retried the "game test" above, and now the house opens properly, but the test will be too far counterclockwise (by 4). Will it stay this way? Was I supposed to do something differently? Was I supposed to turn the house clockwise when off so the test result matches the gameplay result? Thanks again.

Thanks all for the help. I agree it's annoying. Next time I'm near it I'm going to check that the sensor interruptor is tight and will try some of these things. Thanks again.

I installed the JJP Official art blades from Pingraffix. I think they look amazing. They fit just fine in my 75th Anniversary Ruby Red.

Update on this. The problem is very intermittent but annoying. Sometimes right when you start a game, the ball enters the shooter lane and then the winkie guard music starts and the doors open and the vuk ejects and the doors close and it may repeat a lot or not. It does it randomly at any time during gameplay. In switch test, all the switches work as expected. In the vuk opto test, you disrupt the opto, and it repeats this cycle 1 time (doors open, vuk fires, doors close). I discovered something I believe is related. With machine on and playing, I lifted playfield when vuk was behaving properly. The vuk opto connects to the brown opto plug underneath. If I unplug that connector from the opto board, the machine will do THE SAME THING going through that cycle repeatedly! If I plug it back in, it stops. This makes me think either the plug wasn't in good or there's a bad wire, or bad solder joint either on the opto or opto board plug, or could this be a bad opto? How do I best determine what's wrong? (First, I'm going to play a while and see if just reseating this brown plug fixes it. Oh please ). Any idea? Thank you.

Yes I cleaned them a while ago with no improvement. I think there must be some kind of loose connection as it always seems to work when I test the opto.

I agree. You can buy the screws at Home Depot or similar. Make sure to put something non conductive between the switch and metal plate (note that blue paper in my pic). You could probably use thin cardboard like from the back of a notebook, etc. That plexi window thing doesn't look too important. Maybe more cardboard? Or nothing?

Oh I see that little metal bar is the "nut" to hold the two switch screws. You could try just the nuts that come in with the screws.. but I guess that plexi holds the two screws thar certain distance apart.

I installed the precision flippers on my RR75WOZ. If others have installed, would be curious what you set flipper strength to? (Mine were on 22 (maybe from previous owner. ). I'm trying 18.

I'll add the shoes after I finish adjusting them.

I actually Do like and did buy a set of the shoes... but I'm waiting till I play test these new flippers a bit before I install the shoes because the adjustments are on top (and will be under the shoes).
