Sounds like you're about to give Keanu Reeves a hand job.

You'll never finish...that hand is way too slow.

I saw this post and the first thing that I thought, hey! I don't swing that way!

JM you ignorant slut.

Sorry, I'd offer help, but I'm of no earthly good to you on this. Free bump at least.

Sky, I never had a JM but i had a similar problem with MM. My drawbridge stopped working after i put it back in the cabinet. i guess lifting the playfield i snagged the power cable to the driver board and disconnected it. I didn't even think to look at it because i had never disconnected it before. Took me 2 hrs of nearly pulling my hair out. Check any and all connections to/from the hand. Seems trivial and you probably have already but it can't hurt to say it again.

Edit: Keith i just logged into pinballninja for you but he doesnt have anything up there i see you also have an account.. sorry i tried

On my JM I know there are a number of software adjustments for home position etc. but I ended up moving the whole assembly to get things right. The reason I went this way was that I was at the limits of adjustment and it still wasn't right and that was due to the whole mech being slightly out of place.

From memory there are a couple of bolts/screws? to undo right next to the 'thumb' of the glove and the whole mech can be adjusted in place without dismantling any further.

Once I did that, mine has worked without error ever since. Not sure if it is the same problem but worth a try at least?

Does it attempt to move during the power on test? If so, it may be that the x nut is a bit worn and is binding.

The old lady @ Tokyo Spa can help you

You will know what I mean when you loosen the two screws. It moves slightly in the assembly and as I said, finding a different position made quite a difference to mine.

I hear if you use the other hand it plays like a whole different machine.

I saw the thread title & thought it was Gerry!

No that's the normal testing mode. What errors, if any are you getting? If it's moving slightly in both directions upon start up you know that the motors are working. It could be that it's not sensing the motion which could be an opto issue. I can't remember which axis it tests firsts, but I might try switching the opto boards and seeing if the problem switches from one to the other (X to Y).

I'm just tossing that out there.

If it wasn't jumping before it stopped working I doubt it's the X or Y nuts. They seem to start skipping a bit and gradually get worse and worse. It wouldn't or shouldn't be a now it works perfectly now it doesn't type of thing.

Anything on the test report? If not, what happens when you start the game?

As far as switching the opto boards, if it's the X axis that tests first and the Y is broken switching the boards might not matter. It would then fail the X axis test and shut the hand down without ever testing the potential now fixed Y axis.

Hmm...

Hopefully it "stays fixed". My only concern is that you stated that you switched the optos boards that would have obviously changed the centering. If it was having issues both before and after you switched the boards it's odd that just re-centering them was the final fix.

Either way, it's working now...congratulations.

PS: I'm starting to think I might no longer be considered a newbie to pinball. The problem is, I still feel like a complete newbie still.

HURRAY!!!

I saw your earlier pics in another thread. I did you switch the buttons to translucent ones?
