I am going to be using a VGA converter, The question actually doesnt have anything to do with that I dont think. How can I wire my lcd screen to turn on when the cabinet is powered on? Its a jamma cabinet with a 15amp switching supply.
 
Most monitors will remember what the power state was when it is unplugged. If you leave the monitor on and flip the main switch on the machine, everything will of course turn off. When you flip it back on, the monitor will automatically turn on.
You can test by simply unplugging the power cord on your monitor when it is on. Then plug it back in.
 
so what would I do with the monitor plug?? thats my main question. am I gonna have to have 2 cords running out the back on a surge protector?
 
I always chop the outlet plug off and wire it in the cab. That way, everything powers on and off with the cabinet's switch in the back. Don't use the CRT isolation transformer, but use where it ties into the cab. It should be right after the switch.
 
not the best diagram, but the light bulb would be:
-lcd monitor plug
-installed switcher/ +5 +12 power supply
-marquee light

switch being switch in cabinet
bottom pipe being the plug going to wall outlet from cabinet.

that didnt help LOL.

that made me more confused.. in terms of the cabinet, but i now understand how lights work

can I add one more problem I have.. My cabinet was a rally x cabaret. theres this box on the wall, which the power cord goes into. then theres wires that come out. 2 are hanging, 2 go to the top power switch on the cabinet.. im running out the door now but ill snap a picture of this when I get home. This box has a fuse inside so i would like to salvage it
 
LOL damn google didn't have much for me.

put the white and black wires from the lcd power cord and connect it on the switcher's AC input or where the crt isolation transformer connects for AC.

this has the power cable going out. 2 wires going to a switch and 4 wires hanging. I have no idea what the wires hanging are. can you shed some light on that? or should I take that cover off and take another pic? I didnt see the wingnut till I took the pic LOL
 
Instead of chopping the monitor power cord, I always chop an inexpensive surge protector, then wire that to the 120 in the cab. That way you've added a few "outlets" in your cab. You'd be surprised how this may come in handy down the road.

Got a multimeter? This will tell you what those wires are.

epically if you want to plug in a lamp to do maintenance or add a ups for board set.
 
well I have quite a few monitor cables and not so few surge protectors so chopping that doesnt bother me. Im gonna take that cover off that box in the morning, that should tell me what those wires are.
 
i dont even know what that stands for?

if they are in fact referring to an Uninterrupted Power Supply, yeah, that's a little intense!

they probably just meant another power supply though. kinda curious as to what that meant too.
 
well. if this didnt make me more confused. I didnt even see the interlock switch there. LOL I would have wired this up and been confused if it didnt work.

what do I have here?

from the looks of it, to clarify the pics. the green coming from the power cable, goes into that silver box on the bottom. (green/yellow stripe) as well as the ground (brown), The neutral it looks like goes to the fuse. which the other end of fuse goes to interlock, the blue wire coming off interlock goes into bottom of silver box. what confuses me is at the top only a brown and blue wire come out.

The silver box in there is a line filter.

I don't understand why you're taking the interlock switch box apart... that's just where the power comes in to the cabinet. I thought you wanted to wire in a monitor?

Take a normal computer power cord. Cut the plug off that would go into the wall. Wire it up in parallel with the switcher's power source. That would come AFTER the cabinet power switch. This way, when you turn on the cabinet, both devices come on.

im asking, what these wires coming out of this interlock box are. theres 2 white wires hanging and a yellow/brown stripe wiring and brown/red strips wiring hanging. I have no idea what they are.

and yea i dont even understand what wire it in parallel means. im a fucking idiot apparently. I need you to literally tell me. white goes here. green goes here. black goes here. is it that hard? I have gotten 6 answers that are confusing me more and more.

OK. You have the interlock box. Input is a three wire cord. That three wire cord plugs into the wall. You have hot, neutral, and ground. Ground is attached to the line filter and thus the metal of the box.

Output is two wires. Hot and neutral. The metal box serves as a ground connection, but it doesn't appear that this game uses it.

I hope you don't think I'm trying to be condescending, because I'm not. No offense is intended at all, but honestly I'd suggest doing a little basic reading on electrical wiring before you start wiring up AC. You could injure yourself or cause a fire hazard. This is really, really, really basic stuff, the kind of stuff that would be printed on the packaging that electrical parts come in. You need to understand it before you connect things. We already lose forum members as they leave in frustration. We don't need to lose any to electrical fires.

But, for reference:

American standard: Black is hot. White is neutral. Green is ground.
European standard: Brown is hot. Blue is neutral. Green/yellow is ground.

Do a little reading on switches, series/parallel circuits and AC wiring. I don't want you connecting things together until you understand what's going on. I can't tell you "black wire here, blue wire there" because I don't see the whole circuit. I can tell you that you're going to cut the plug off a computer power cord and strip back the jacket, and you're going to see one of the above standards. You then need to hook the wires up to their "mates" inside the game, someplace after where the cabinet switch is. But I can't see the whole wiring harness. I can't tell you what particular wire color code your particular cabinet used. There is no standard color codes for the wiring inside an arcade cabinet. Not to mention how often these things get modified. You will have to follow the wires yourself.

An EASY way to find the switched AC is to find where your power supply gets it's power from. Or, where the marquee light gets it's power from. Or where the isolation transformer (if still present) gets it's power from.
