Quoted from PinChatt:

Replacement moon belts for Apollo 13 may be available in a few weeks if all goes well. I've been working with a supplier to have them reproduced. Once I get a sample and confirm fit on my game, I'll post an update.

Been looking one for years! Thanks for doing this!

Quoted from TecumsehPlissken:

What is that on your Fish Tales a Topper's topper ?

LOL yeah A local guy paints these scenes usually on saw blades and hand saws for display purposes so i asked him to do me one on a standard board with some scalloped edges and of course, it had to have the words "FISH ON!!"

So i popped the hood up for a closer look underneath today and discovered the previous owner still had all the connections attached for the moon but had just removed the 4A fuse. Now i only had some 3A and 5A on hand so i whacked a 3 in there to see what would happen which instantly blew. Just going off what i've read so far it's most likely a blown transistor on the moon magnet board?? i'm presuming that's on the driver board itself or is there a separate board for that? I'm yet to print out the manual for this but can anyone tell me which transistor on the board would be the potential culprit? Guess it could be a short in the magnet itself also or an exposed wire shorting too. What's the best way to remove the moon unit assembly for inspection, just unbolt the brackets from under the playfield and pull the moon out from the underside?

I've gone "inside the moon" probably 3 times. I choose to remove the retaining ring on each side of the moon axle, spread the metal clamp/bar holding the moon by hand. The moon halves pop open easily and allow for inspection of the interior. An easy check once you've accessed inside the moon is to check continuity on both wires from the magnet to the fuse/underside pf connections due to moon movement/rotation wear potential. Also make sure there's a zip tie or some other stop on the wires just inside the moon shell to preserve some slack inside the moon and prevent motion from pulling on the connections inside.

Cheers!! It does look like the magnet wires have been extended in length as there is a visible join underneath and the wires do look intact. It's getting on into the early morning here so i'll pop the moon open later today and have a check with the DMM. If that side of things tests ok then i'm guessing there's a blown transistor somewhere on the driver board, something is shorted blowing that fuse.

#556 27 days ago

Did some continuity testing on the wires into the magnet and if i'm understanding this correctly the magnet coil must have shorted out.
Attached the alligator clip to the magnet wire that goes to the fuse clip and then tested both wires on the magnet coil at the place shown and both wires had continuity. Tried the alligator clip on the other black wire that comes from the magnet and then tested both wires as shown, same result. This would make sense that the fuse is blowing and if so then the transistor should be still ok on the board.....hopefully the fuse has protected the transistor
Please correct me if i'm wrong guys.

Set your meter on ohms and measure the resistance. It's normal to measure continuity through the magnet coil. The resistance will tell you more. I would expect a good coil to measure something around 5 - 20 ohms or so (I don't know the specific value for that coil.)

You will also need to check the transistor. A fuse does not blow fast enough to protect a transistor. The purpose of the fuse is to prevent fires, not to protect components from failure.

The most likely cause for the fuse blowing is that the transistor is shorted and leaving the coil energized too long. That coil is only designed to be energized for a few seconds at a time, max.

Thanks for this, i wasn't sure if the continuity reading was accurate or not. Do we know which transistor on the driver board is responsible for the moon magnet? I don't seem to be able to find mention of it in the manual, i'm used to Bally/Williams manuals having the transistor list showing which trans for which coil. Will do another check of the ohms also.

#559 26 days ago

Did an ohms test of the magnet coil and it was showing 5 ohms which is about right for a working coil according to this article i found on the internet >>> http://pinballnovice.blogspot.com/2015/12/apollo-13-my-moon-my-magnet.html
This article also showed me where the little magnet board is and once it was pointed out i had a DOH moment LOL, had spotted it but didn't think it had anything to do with the moon magnet.
Reading through this article gives me some areas to check, the transistor on the little moon magnet board first and foremost. I might need to remove the transistor from the board to test it properly as i'm not sure i can test it in situ. I have done "dirty" trans testing on Bally/Williams machines ( for coils ) where you are grounding the metal tab of the transistor which will make the coil fire. Don't think that will work for this particular transistor.
The article mentions a board that runs the 7 digit display that sends signals to the little moon magnet board AND also a potential for the issue to be back on the driver board itself.
Gonna try testing the transistor (or just replace it ) and then go from there.

The most likely problem is a bad transistor on the moon magnet board. It's a MOSFET transistor, P20N10L. You can use the more common IRL540 as a replacement. To test it, set your meter on diode test and check across all three legs. You should get a reading from Source to Drain of between 0.4 - 0.6. All other combinations should read open. You can test it in circuit, just unplug the connector or remove the fuse to the coil so you don't get any false readings.

FYI, grounding the metal tab of the driver transistor doesn't actually test the transistor itself. That is testing the wiring and power from the coil back to the driver board. You are essentially bypassing the driver transistor when you ground the tab.

Could someone do me a favor and check what coil is used for the trough up-kicker? It's coil #1, and the manual actually lists three different part numbers for that coil depending on which page of the manual you are on.

Page iv, Coil Chart lists it as a 25-1240
Page 23, Playfield Coil Locations lists it as a 24-940
Page 71, Trough Assembly lists it as a 23-800

When I got my game, there was a Williams SG-23-850 in it. That's obviously not original. The reason I'm asking is that the up-kicker seems to kick the ball too hard. I just had to get the exit scoop re-welded because it had cracked. So I'm going to try one of the lower power coils in that location. I was just curious what coil was originally installed there. The manual isn't much help in this case...

Thanks, yeah i already knew which type of transistor it was and have some IRL540N on order (should get them in the mail tomorrow) I did discover upon removing the small board that the IN4004 diode was virtually cracked in half so i have already replaced that, luckily had a few spares in the parts box from previous work. I'm just going to replace the transistor straight up but will most likely test it once removed anyway. Hopefully that's the main culprit

Replacement moon belts are now available from Pinball Life. They were able to reproduce them based on my original, damaged belt. I've already tested one of the new ones on my game and it fits and works perfectly. Order now and get them while they are in stock!

Special thanks to Terry for making this happen!

OK....so now i finally AM going to the moon
Replaced the transistor just now and it's working 100%
Whilst waiting for parts to arrive i did a refresh on the boosters of the rocket, just tidied up the red (with a brighter colour) and made the outside edges black, refreshed the chrome/silver of the boosters also. I have left the white for now but might do a full repaint later on down the track.
Next is to replace all the half perished rubbers with Titans and i'm going to put some Comet spotlight towers on the slings (waiting on packages). The lower half of the playfield is quite dark on this machine i think, possibly more so than even JD.
Loving playing this title
Has anyone ever done some target decals for this machine??

I'm not sure if anyone has reproduced the target decals. I need the decals on the pop bumper covers. I did get a scan of the "Danger Exhaust" decal on the trough scoop when I had it out to re-weld it. It would be great to get a set of files together that have been cleaned up in Photoshop so they are ready to print.

Bit of an update on my moon magnet, worked briefly and then stopped again
It's not blowing the fuse so i'm pretty sure the transistor on the moon magnet board is still ok. I pulled the 7 segment board and tested the 3 transistors on there that are involved with sending the power and hold signals to the moon magnet board and it appears (if i've done the testing properly) that at least 2 have gone awol. Other thing i did notice is that this board has either been repaired a few times before (replacing the 3 transistors) OR it was done really badly the one time because the tracks are lifting somewhat at 2 of the 3 transistors.

I recently had ordered an after market moon magnet board from applejuice whom i've bought items from before and decided to ask Jim if he had any plans on recreating the 7 segment board also as it seems to be as problematic as the small moon magnet board. I know he does awesome work with his boards and mods so was hoping the 7 segment board could be done also. Received a reply from Jim that he'll look into doing this board soon so if any of you guys want to replace either the moon magnet board or (hopefully soon) the 7 segment board with more robust versions this is his website >>> https://mypinballs.com/electronics/store.jsp
In the meantime will probably send my board to a local tech guy cause i'm a bit nervous about replacing the 3 transistors considering the track issue. I don't have the best soldering/de-soldering gear so don't want to risk stuffing the board up.
I'll definitely be buying a more robust version from Jim when he gets to doing these as it will be far better than the standard Sega board, plus of course those original boards just aren't available anymore.

Progress. Some adjustments to make still but I have this now. There will be sone options for different control/pulse patterns for the moon magnet to. Maybe an option for different segment colours to (not sure yet)

Never thought that I'd get a replacement moon belt for A13. My new belt is safely stored in the coin box for that inevitable day when the last half of the original belt finally disintegrates. Thanks for making this long unavailable belt "obtainable" once again!

I ordered a belt & the 8 Position Membrane Sensor. They will serve as insurance that I will never need them.

Made of the same material or is it more resistant?

#579 1 day ago
Quoted from Morgoth00:

Just added the spots today I might adjust the angle a bit yet but happy with the results. My camera does tend to adjust for light so if it's too bright it backs off somewhat but also compensates for when it's a lot darker and makes things appear brighter. I can definitely say it's made a hell of a difference to the lower half of the playfield. I also added the same Comet Quasar bulbs to the upper spot towers too.
Edit** I did have some of the mancave lights off for the 2nd pic so it looks a little darker in the top part of the playfield, if anything the contrast looks more like it does to the eye.

It's made of similar materials. The belt uses steel wire that is over-molded with plastic. It's hard to say what these new belts will look like in 30 years.

Thank Terry at Pinball Life. He did a lot of the work and took all of the risk! I just provided a sample and some measurements. Then I was the Beta tester once I had a sample in hand.

Now if I can just convince someone to reproduce the ramp...
