What does the isolation transformer on a Mortal Kombat look like??

I really need help here people...  I just got my new chassis for my WG 7000 from Video1963 off Ebay.  It is a new Wei-Ya chassis.  I think I have figured out how to connect everything EXCEPT the power to the chassis.  It came with like a standard household style male plug (2 blades).  I can't seem to find what this is supposed to plug into in the cabinet.  The only wires that are unconnected coming from the cabinet that run up to the monitor is a female type plug that accects a male plug with round pins.  It has a purple wire, green wire in the center, and a purple wire with a yellow stripe.

Help please?  All I want to do is get my first arcade machine up and running!  -_-

Some monitors actually have those household plugs. If you want to use it you can cut the plug, split the lines and splice it into your input line. If it has a household plug, that means it doesn't need the iso-trans. You can totally by-pass it.

The plug with the 3 wires that you've got in the cabinet is most likely the power for the old monitor (which would have required the iso-trans and would already lead into it if it's wired properly).

Without seeing the wires, it's hard to see where they go, but you SHOULD be able to cut the monitor power's plug off, split the wires, and splice them into the 2 purple wires leading into that plug in your cabinet. Using an iso-trans when you don't need it is acceptable.

The other fool-proof solution is to chop the monitor power plug, split the wires, and feed them directly into the power cable coming into the machine.

Lastly, if you're concerned about chopping the monitor's power plug... Plug the arcade machine and monitor into one power strip and plug that into the wall.

Ok, everything is hooked up now, and it works great.... with one exception.  The picture is upside down and inverted.  How do I fix this??

I figured it out...  I had to reverse the yoke wires.  This fixed all my problems, now my MK is complete and running!!!   ;D ;D ;D

Drew Karee can bite me! ;)

Pics to come soon...

Oh yeah...  a little safety tip.  Make sure the power is off before touching any bare wires in or around your monitor chassis.  I gave myself a good shock about an hour ago when I was reversing the yoke wires.   :o

What method did you end up using for power?

I just ended up plugging both the cabinet and the monitor chassis into a power strip.  I was nervous when I first powered on, but everything is working fantastic.  Thanks for the advice, by the way.   :)

HARUMAN!!! Stop right now and turn that machine off... Let me give you a couple solid tips:

1. CHECK YOUR MONITOR MANUAL to find out if it requires an isolation transformer or not. Some isos actually HAVE plugs on them. I guess it's easier than splicing wires. So just because it works, doesn't mean it shouldn't be isolated for safety. Check that manual.

2. NEVER EVER EVER touch, move or do anything with electronics and wiring with the power on! EVER!!   The reason I stress this is NOT just to prevent risk of shock. What about the risk of damaging your equipment? You could have fried your new chassis!! Slap yourself for me, will ya?

Ok, I'll start by apologizing. I've never seen an isolation transformer with a plug on it. My experience with a monitor with a plug was I was told I wouldn't need the isolation transformer for it. However, there's no reason NOT to wire it through the isolation transformer, even if it means chopping the plug off.

Just because it's working right now doesn't mean it shouldn't be using an isolation transformer (if it does, in fact, need one).

The first post in this thread: http://forum.arcadecontrols.com/index.php?topic=34544.0 complains about a Wei-Ya that comes with a plug, but needs a transformer.  So Wei-Ya is known to do this.

Definately find out for sure before you power it up again. 

[hint]  For best results with monitor questions, I'd post in Monitor/Video, as that's where the monitor experts live.  [/hint]
