Hello guys,

I took delivery of my first pin today, a Demolition Man in pretty good shape. I was partial to this game as my dad bought it about 20 years ago so I grew up with it.

Anyway, The game isn't really functional at this point because the machine thinks the coin door is open (message on screen) and the flippers and ball launch do not work.

I understand the two white switches inside of the door are the culprit, with the top one cutting power to the high voltage.

When I hold that top switch in, everything works fine. Let go and flippers do not work, whether to door is open or closed.

Any ideas?

I also don't see how the door closing would physically touch press this switch, or any other mechanism that detects the door closing that I could check.

Thanks in Advance.

When the door is closed there should be a metal plate on the coin door that pushes those buttons in.

When con door is open high voltage is turned off for safety. Look at the pictures of a coin door and notice the silver metal piece on the side of the door. Do you have that piece or is your coin door missing it? If it is there you may need to adjust to ensure it presses the switches when closed.

Well, that is the problem, the plate you are talking about is not there, so when I close the door, nothing is hitting that switch.

Also, any idea what the unconnected wire is near those switches?

Greg, please give the tech Wayne a call tomorrow. We will absolutely rectify any situation that arose from the journey to you. That demo man probably has under 150 games played on it. look at the stock flipper rubbers, they look like they have never been used.
Regardless, please speak to wayne in the morning. We will rectify anything that is not working 100%. if I need to hire a tech out there I will. You have a warranty, so do not lose any sleep over it.
You could not find a Demo man in as nice condition as that one if you tried. It is flawless. I'm sure the fix is something very simple.
We are a new company, but we are honest and we stand behind everything that we sell.
I will have some not so kind words for the freight company...

You can also pull the switch out, to enable power.
Since there is nothing to close it, this should get you by.

If the machine was shipped, you may want to look around the bottom of the cabinet and see if it is laying around somewhere or that it didn't come off and get caught up in the wire harness.

I have scoured the machine and do not see that plate anywhere. Looking at the screw holes, it does appear it was screwed in there at one point.

Are you guys saying if I just pull that switch out completely it will work? I don't want to lose the safety feature of the switch with young kids in my home, but it may suffice until Manny (who has been great to work with) comes up with a solution.

Look for a yellow metal clip in the goodie bag or in the cab . This one would be put over the switches.

As my understanding goes, the "yellow clip" is used when the coin door is open and is for the purpose of activating the power so one doesn't have to hold the switch in whilst in test mode. The coin door should have a plate behind it to do this very job!!

#13 4 years ago

That is true .

#14 4 years ago

Correct, but it is not present on his coindoor, with the actuator, gregdole7 is at least able to play a game.

#15 4 years ago

Fair enough, if it was me i would make up a plate to fit or track down an original part though.

Quoted from gregdole7:

If you pull the top switch, it will allow HV in the game, and since the coin door doesn't have the normal part to push the switch in, even with the coin door closed, you should be able to play a game.

The other switch tells the game that the coin door is open.

I looked for the yellow actuator as well, but it is missing too.

If the coin door is locked there's no danger.

1. Pull the top switch out as Chris indicated.

2. Close and lock the coin door.

3. Power-up and play the game.

The safety aspect is really more for the safety of the machine so that clumsy debuggers don't short coil voltage into the switch matrix and other circuits.

Do the above and if you are concerned about the safety with your kids, pull the key out and put it in a safe place.

The yellow clip is more often than not missing. Out of 20 pins I have 1.

Not missing. Your game doesn't need it because the high power interlock switch can be pulled out. So your game didn't come with one.

The yellow clip only came with a few titles that had the old switch that couldn't be pulled out.

And one of those games might have been Corvette. Corvette is the most irritating game to debug, especially the jiggling motor assembly because coil power must be on, yet you need to operate the coin door diag switches.

Corvette is one. Judge Dredd is the first game I recall coming with the yellow metal clip.

That's interesting as the Demo Man manual speaks of this part and has photos of it. Either way, thanks so much everyone for your help. Hope to get the Claw error issue resolved next.

Thankfully there has never been a manual error. ( huge sarcasm intended )

Disconnected all 4 cables from the top switch and it still does not work.

Any other ideas?

As I previously mentioned, high voltage works when the switch was pressed in.

#29 4 years ago

Can you post a picture of the wiring side of the switches ? I wonder if wired wrong or something.

Why did you disconnect the 4 "cables"?
That's the same as opening the switch, which will CUT power.

At the risk of sounding harsh Greg, you aren't listening.
Pull the switch outward. It will work.
You're a newbie around here. A few of us have been around the block before.

Pressing in the switch completes the circuit thus turning on the high voltage. Simply removing the wires from the switch will not complete the circuit. Those wires go to some connectors and you must pull the entire switch.

Hopefully you contacted the person who sold you the machine and they are sending you the missing part but a quick solution if you are not comfortable would be to use some electrical tape to hold the button in (basically acting like the yellow service switch activator tool) so you can play while waiting for your new part.

He can play right now...IF he simply pulls that switch outward. I don't mean REMOVE the switch, I mean instead of pushing on the switch, pull on it.

Thanks for clarifying, Chris. When I read someone above state "pull it out", I thought that meant remove it. While that didn't made sense to me, that is what I thought you guys were saying and gave it a shot. When that didn't work, I resorted to the electrical tape fix mentioned above while I wait for a new coin door plate to arrive from my seller.

I will simply pull the switch first thing tomorrow and hopefully be on my way to toublesbooting my next problem: the retina scan not pushing my ball hard enough to get it out of the hole.

I do appreciate all the help, this has proven to be a valuable community in my entry to the hobby.
