Nope, it never hurts to have extra's, I am trying to keep any extra boards I end up with for whatever reason, too many times I needed a board I had, sold it for less than it costs, and had to spend more to replace it. Hell, if you replace it, I will buy it myself.

At least if you do want to try this route, the board is cheap enough.. if you wanted to split it, I would give you 20 for yours and you could by this one for 40

Worth a shot, have you switch tested your coin door switch by chance? In switch test you just press in the button, just curious if that is working.

Are there wires connected to the top one? I just checked mine, the top one does nothing in switch test, only the bottom. Did you order the rom yet? I still think your best bet is that replacement board from K's arcade, I honestly still think the software is the only thing left that makes any sense as to why it works with demotime but not the current rom.

I spoke to my buddy & he was thinking it was ROM related. What did John say?

I just do not think it is the rom... if it was only not working with LX4, then sure, but you say you have 3 roms now, and only 1 works. I still think the problem is in that aux driver board. My offer to split the cost of the new one with you stands, I can shoot you 20 paypal as a gift, you order the new one from K's and send me the old one.

Let us know how it goes

Did u try removing or replacing the batteries?
This rom version might be finicky and removing the batteries might do he trick.
My claw was acting up recently too and this worked for me. I have the profanity roms.

What do you mean by new card?

So, with any other rom, except that Demo Time that does make the claw work, if you go into claw test, does the magnet work at all? If you were to hold the ball there would it be held at all or is it just nothing at all?

Have you done any voltage checks yet, there are several test points on the driver board where you can measure.

Ok, so it say's magnet error when you go into the claw test menu. And you put a new aux driver board into the game already.. Ok, time for some research, let me dig around.

Found an old post that mentioned the same problem, turned out this board was bad http://www.marcospecialties.com/pinball-parts/04-12330.. there was also mention of the elevator not moving up and down properly, do you find your elevator is slow or hear any scraping or grinding noise?

Going through the manual, magnet error

This message is displayed when the game is unable to pick up the ball from the elevator platform with the claw magnet, this can be caused my a defective magnet in the claw arm, or the elevator hold switch being broken.

We may have covered this, but when you run the claw test, does the elevator hold box have an x in it when the claw is trying to pick up the ball?

I'm still willing to send you another one to try... no charge

This is getting exciting....

I hope you get this worked out. It seems like quite a ride. I'm not good at diagnosing anything like this, but if you need any pictures of mine, let me know.

Ok, so in a test run it worked, when you started the game it did not. Did you try the test again with you holding in the button? Also, when you say the hold is always on when the ball is in the elevator, you don't mean even when it is at the bottom as well do you?

Ok, so you went into test mode and got the ball out, so it worked 2 times in test mode? When your running test mode, are you holding in the button on the left side of the coin door, the white door button, or not holding it in?

And when the elevator is down, the hold x is not still on right?

Ok, now this is a longshot but I am curious, take the glass off, keep the coin door open, hold in the white cabinet switch and start a game, just roll the ball down the cryo claw inlane to start it, then roll the ball up to the elevator, If it works in test this way, I want to see if it works during gameplay this way.

Great, post the results.

I'm wondering if the 'works with Demo time' isn't a massive red herring, have you switched the ROMs back to see if it still works with the Demo Time ROM? (Apologies if you have, I only skim read the thread)

Before buying anything, I would test 100% every single switch and opto related to the claw operation, if you look in the manual at the switch locations page this will help with that.

95% of the problems I've seen with the claw are to do with the claw opto, due to WMS cheaping out on the opto hardware. I can highly, highly recommend this board if the claw opto board is faulty:

The opto board controls the left and right movement of the claw itself, I agree that replacement is a better option than the original, I bought one myself, and they will soon have the one for the bottom of the elevator shaft, I had sent them my old one which was not working, and just received the new version.

He has never mentioned any issues with the left and right movement, and we have gone though the test options and both left and right do register.. I really thought there was an issue with the Aux board that controls the magnet, but a new one was installed.. This claw working in test mode is new, now it may have to do with the new board he installed, not sure... still going though it.

When he checks in later, will have him double check the left and right movement in test mode again, to make sure they are both registering. Usually you get a claw out of range error message though, and he has not gotten that.

Yet it works in test mode... Ok, the mystery continues...I will dig around some more, going to see exactly where the voltage for the magnet comes from.

Ok, new thing to check, on the fliptronic board, J-907-6 is a red violet colored wire, this is voltage to the claw magnet, J-902-6 is a yellow violet wire again on the fliptronic board.. Check both of these connectors and make sure the wires are in tight, check the pins on the board for any corrosion, and recheck all 4 fuses on that board..

Do you have an Alligator wire clip, a wire with alligator clips on both sides?

On that fliptronic board Q2 is the big tip 36C, there are 4 of them in a row..

This board is in the top left hand corner. Also, pull the ribbon cable coming from the CPU to the fliptronics board off and double check the pins, make sure not a single one is bent
