Looking for some help setting up power in cabinet.

[Misto]

Hey,

I picked up a partially gutted cab a few weeks ago in order to turn into a Mame machine.  The cabinet didn't have a game board or power supply but had most of the other power setup, wiring, and an arcade monitor already in it.  Ideally, I'd like to use this monitor in my setup instead of mounting a new one.  The problem is the AC Power cord and the power supply have been removed.  I got a replacement supply, but I was hoping to get some help as to how/where to attach a power cable and if the rest of the wiring looks correct.  I added a bunch of pictures to show how its setup.   I appreciate any help or advice!

I might can help you on the wiring of the power.
Looks like your "HOT" (Black) wire connects to that fuse in the box on the wall. It should connect to the wire that appears to be stripped.
The "NEUTRAL" (White) wire will connect to the blue wire in that same box. (The blue that is currently wire nutted to the green. Remove this wire nut and separate the blue and green.)
The "GROUND" (Green) wire from y9our power cord will connect to the green wire in that same box.
Also, the power supply doesn't appear to be right.
FG is frame ground and should connect to the GROUND.
AC N is neutral of the 120 volts.
AC Line is Hot of the 120 volts.
Im assuming you are in the states and have common 120 VAC power.
But, if you are going to mame this thing you probably wont need any of that stuff, except maybe the isolation transformer if you intend to use the same monitor.
If you do use same monitor I think you will need a special card for the computer that outputs a signal that monitor can handle.
But I have never tried that before so Im sure others on here can help you with that more than I can.

Ok I'll try that out tomorrow after work and see what happens.  Just for be sure, is this what you were referring to for the "hot" wire?



As for the other points, I do live in the states so that's not an issue.  I do plan to use the monitor (a g07 that was in the cab), so I'm just hoping to get that powered on so I can plan accordingly.  The rest of the setup is already connected to the monitor as well, which is why I'm just keeping it as is for now.  And if it does work, I already have the signal issues sorted out, since I can see where the RGB and sync wires come out of the monitor which I can wire to a VGA connector and use either a special gfx card or software to handle the rest.

Thanks for the help!

That black wire that your arrow is pointing to is where you will connect the HOT wire.
That small square block inside the box is a power filter. The input (120 VAC from your wall power) is on the left of the filter. Output is on the right.
Hot goes to the fuse, it leaves the fuse, goes to the door switch (which you will need to tape the plunger in on the switch if the door is not installed), it leaves the switch and goes to the brown wire on the filter.
The NEUTRAL from your power cord should connect to the brown blue wire of the filter.
The GROUND of your power cord should connect to the green wire of the filter.
Coming out of the filter, it should connect to that big isolation transformer.
If you are going to mame this, and use a computer, you probably wont need anything else (AFAIK).
The transformer is needed to isolate the monitor.
You can tie your PC power to the incoming power cord for now to get you started. Or just plug the pc into another outlet.
I have never tried to use an original monitor on a mame setup, so if anyone sees a problem with this, please speak up.

Sorry, just noticed you are new to this forum.
Welcome aboard!

And double check your connections on the power supply, it looks like the hot wire may be connected to the FG on the PS. I may be wrong, but make sure it is not, because if it is, when you power this up, the case of the PS will be HOT and will be a shock hazard. FG needs to connect to ground. It looks like you have green wires on that fuse behind the PS, so don't trust green being ground. Ground should never be fused.
If you have a multimeter, you can trace out the wires a lot easier.
It may be best to unhook the PS and tape the wire connectors until you figure all this out.

So much info, thanks again.  I'm about to go out and start messing with it now.

I was planning on removing the PS too before doing anything, unfortunately I don't have a multimeter to trace the wires.  Might pick one up if this doesn't work.
As for the pc, I plan on just powering that separately for simplicity.

I'll do a follow-up post with findings.

Ok, an update.  I got power

The downside is the monitor did not power on.  The fan on top of the cabinet did power up however so I now know the power setup is wired correctly.

Would the monitor (a g07) need a signal before anything would happen?  Is it possible it is getting power just won't show anything because of that?

As for the actual wiring, you were correct on the AC cable wiring.  The pink and blue wires in the back near the transformer were both for AC power (blue for AC/L and pink for AC/N) and we had to add a wire for the FG, so it wasn't too difficult.

Thanks again for all your help!
