lol. Tell me about it.

I don't think it can be beat, you just make it last as long as possible and get as many points as possible.

I'm finally shopping out my JM. The x-motion of the hand didn't work (surprise, surprise). It apparently wasn't the first time the game had this problem, as my x-nut was quite the hack!

Here's a picture of the old (handcrafted) and new (genuine) x-nut. I'm actually impressed at the ingenuity that went into hacking this together. What looks like it might have been a big t-nut had the threads, and the bigger piece was bent to keep from rotating freely.

Also, what's the proper setup of washers and nuts on the lever to lift balls off the matrix?

Edit: actually, I just found it on page 2-25 in the manual. Nevermind!

The bill of materials calls for five red lamp covers (condoms). My game had them, I removed them without taking pictures, and I can't figure out where they go!

So... where do they go!?

Thanks for the pictures! I revisted my pictures once I knew what to look for, and I found that I did take pictures! (This is what happens when you take too long to shop out a game!)

As I'm preparing to reassemble my Johnny Mnemonic, I'd probably be stupid not to buy the plastic protectors, right? All of my plastics are in good shape.

Goodbye, $40.
Hello, plastic protectors.

At least I already know how to attach that one that sticks out to the left of Crazy Bob's.

Ugh. Now do I need to buy Cliffys, too!?

X nut is a possible culprit. If you can slide the glove left and right and the nut slips on the threaded shaft, that's a problem with the X nut.

Whaaat. I paid more than that for the dirtiest game I've ever seen.

But hey, it's clean now!

I finally diagnosed and solved a strange "ball in hand error" that had been plaguing me for a little while. I figure it's worth documenting because I've never seen it mentioned elsewhere, and it's not very straightforward.

So, I'd occasionally get a "Ball in Hand Error", even though I knew my ball in hand switch was working fine. Every time the error and credit dot popped up, it'd go away as soon as the ball was loaded into the hand. In switch test, it never failed...

The clue to what was going on was that in attract mode, after sitting for 10 minutes or so, the game would suddenly start moving the hand. Intermittent and spontaneous problems like this got me thinking opto problem.

So I put the game in switch test mode and walked away. 10 minutes later, I heard a quick "beep beep". I ran to the game, and the display said the last switch to trigger was the VUK opto. Bingo. This was exactly what I expected, actually.

The problem was that the VUK opto would occasionally flicker, and the game would think there's a ball in the popper. It'd try to kick it to the glove to clear it, and because the ball in hand switch didn't detect the non-existent ball, the game reported a ball in hand error.

The fix: well, I wiggled all the wires to the optos but didn't find any bad connections. So all I did was clean the optos. I haven't seen it happen again, but if I do I'll either do a more thorough cleaning, or I'll replace the optos.

And that's the story of my very misleading "ball in hand error".

So you've got motor problems rather than switch problems. That's good to know.

So your motors aren't moving at all, right? Do the flashers work? Those use the same 20 V power source as the motors.

Oh wait, is the coin door closed for all your testing?

Check LED 5 on the power driver board for the presence of 20 volts. It should be lit. This is also power for flashers. Check fuses F111 and F112. The coin door interlock switch can also break this circuit.

Check the three connectors on the motor board under the playfield. Check power driver board connectors J118 (ground), J107 (20 volt power), and J126 (solenoid/flasher drivers to signal movement to the motor board).

Report back!

Thumbs up!

Keep in mine that the fuse probably (but not necessarily) blew for a reason, i.e. it's sort of likely to blow again until you find and fix whatever was wrong the first time...
