We've got all the wires organized now down to the essentials. Only problem is, we've got four wires on the power side of things that go nowhere. Every other one has a connector on the edge of it with a wire in it's proper place, except these four. My guess, is that these four went to the on and of switch for the unit, but I have no idea if they should be tied together, in pairs of two, etc.

Assuming all WOW had standard colored wires, and these where not changed over the years..... or you can guess just by looking at them, can I take photo's of these wires in the hopes someone here can idtentify them? These are the last four mystery wires needing to be identified.

Also, our Power Supply is an Exactron 8812. Should that be dead, what would a good replacement for it be and where can i easilly obtain one? I'm also hoping my RGB convertor is not damaged...I dunno if the guy I found it from online still makes them.

Thanks

that power supply is just a basic switcher. you can get them pretty much anywhere, ebay, bob roberts, arcadeshop, etc, etc.


as far as your wiring issue, when you say wires on the power side, do you mean from the transformer block/area or are they wires going to your power supply? if they're going to the exactron power supply they may not be original to the game itself, so try to see what they connect up to. i have an unmolested wizard of wor, so if you can post some pics, i'll take a look at mine and see if i can give you some direction on that wiring.

Some Hopefully more clear shots..

In cleaning up the wiring, I noticed one or two grounds had come loose, so I hope I didn't fry anything, but knowing my luck Probably did

Thanks for any identification if you can tell from that. From what I can tell, they go into both, through the transformers and power supply.

I assume you're talking about the black and white wires? Those might be 120VAC....feeding the power supply and the transformer....or 120VAC output from the transformer for feeding the monitor.

You really should get rid of that busted interlock switch....just connect the two blue wires together...and connect the two brown wires together.

the yellow/red wire looks like wire 14 on connector p2 going to the logic board, which goes to the interface board for the video output. but, the stripes are longer on mine. the other white/blue wire i don't see looking at any of the harnesses on my game.

the green w/ yellow stripe should be your earth ground.
 
Heya,

You know, I had totally forgotten that the monitor had at least two seperate wires going to it. You're probably correct that those might have been for the monitor itself. That RGB to RCA convertor board has been on there for so long, that I can't even begin to remember much about the monitor, other than the fact that it died when I damaged to the neck board during movement.

So now, where would my on/off wires be located? On the Power Cord plug 'above' the interlock switch? Or if we re-wire the interlock switch the way ELutz would we not even have to worry about the On/Off switch wires?

If that's the case, and it STILL doesn't start up, we may have to look at replacing the transformers and/or power supply. Is there a modern alternative to these two devices that can be readily bought new at any retail store?

Thanks for the combo needed to get rid of the interlock switch, BTW... mixing and matching wires is not a good habit to keep to try and find the right combination to things :).
 
Wizard of Wor AC wiring

A better title might attract more help.

OK- now that I sound like an ass...


Check out the manual PDF for the game. Midway was pretty good about documenting this kind of stuff in the schematics and diagrams.

I've got one pulled up here.
It looks like white/blue and yellow/red combo (W-BLU, Y-R on the diagram) supply 12VAC for the coin door lights.

It also looks like there is a white and a black wire (WHT * and BLK * on the diagram that feed the monitor jack. You should have about 120VAC on these lines. These are the only four wires coming from the MT-92 transformer. I think I've got a few of these if you need one.

I can't tell what the note says about the asterisk * above. It might say that the wire is a smaller gauge (thicker). I don't have a better schematic here.

So, measure out the voltages. You can also look at the wiring diagram in the schematic to check your work.

heya,

As you can probably tell, wiring diagrams are sort of like greek to me. Doesn't help that one is a little slow with a learning disability either, so I'm trying to feel my way along best I can while my electrical expert co-worker is out on vacation. I'm hoping to have it up and running within a week or two before Turtles in Time - Reshelled comes out for the XBox. I've been wanting to do a video walkthough of the original arcade for ages now..

So, here's a question. The M92 is the smaller transformer, right? So what would the b igger one be for, since all the outgoing wires to it are cut? I'm trying to remember, and I THINK those might have been for the monitor as well...To keep things more organized, we where thinking of unbolting the bigger transformer if it's not needed .
 
The bigger transformer with more wires feeds the power supply with AC voltage.

Here's what the diagram shows:
yellow wire- Center tap to pins 1 and 2 on the 12 position connector on the power supply
grey wires- 9VAC relative to center tap. 18VAC between them. Connected to pins 3 and 5.
black wires- 14.5VAC relative to center tap. 29VAC between them. Connected to pins 10 and 11.
W-G and Y-G (white/green and yellow/green?) Seperate winding (isolated from other outputs) w 12VAC to pins 8? and 12 on power supply.


The power supply generates some DC voltages for the logic on the game boards.

Good luck-

Kerry

And your wires were cut off because that transformer is no longer being used. Someone remover the original power supply and installed that switching power supply.

Ahh, good. So I take it that means we can detach the bigger Transformer to make it lighter. That'll make it much easier to design a more portable unit.

It also means that should we end of needing to replace all of it, only need to buy one transformer and one power supply.


All Good news :). Hoping my electrical expert will be back sometime this week so that can at least be done with the proper tools..
