okay i just checked the cab inside again and noticed something.
this wire right here has a plug at the end, it goes around the monitor... its 2 wires, as u can see with a black plug at the end. whats this?

i wish someone could just explain to me 100% how to get this right. like for instance, from the wall it goes here, and u have to put a wire there and also do this and that. just kind of a step by step how to thing.
okay some questions from what i understand i should do. in this picture. http://i53.tinypic.com/104q5c4.jpg
hookup the transfomer as is from the wall, but the 3rd wire from wall thats ground, should be connected with a wire to everything thats metal?
around the screen there are metal bolts that hold it in place, should i have a ground wire to that? ground wire to transfomer and also the adjustment box of the monitor?
control panel is made from wood and everything is wired to the jamma harness. should i have a loop going from the jamma harness ground that the buttons are connected to going to the jpac ground also?
how about my computer should that have the ground wire attached to the case? lol stupid question but i have to ask.
is this safe todo? as in i wont blow the monitor or something like that , or cause a fire etc?
surely it cant be this complicated. i just need a step by step thing and its done and dusted.

ed the pic 3 u talking about, thats the ground going to the jamma harness. but there cant be no ground/earth cause there is not a ground/earth wire that comes from the wall...
also that powersupply will be removed, i just included the pics, since its not needed when u run the jpac and could only cause some problems or even burn out from what i was reading.
im a lil bit confused about ur reply sorry man.

hi
if u are using this on a mame
>http://www.ultimarc.com/jpac.html<
then yes u no longer need the power supply
from what i can see of the pic of
the transformer pic #2
that black wire is a tap
what may i ask is your :main's: voltage
120 or 220 ?
where u see the fuse holder's on the right of the transformer
that should hook straight to your monitor :ac: in

Unfortunately there is no magic answer here from what your showing. you keep bringing up the monitor. does the monitor work or not? is video not getting to the monitor.
From what your showing, things look to be hooked up correctly.
I'm a little confused because the picture that you reference as showing 2 wires with a black plug going to the monitor.... I don't see the monitor in that picture.
As far as grounding the cabinet to earth ground, the ground starts at the power cord and goes into the cabinet. from there make sure it has a path to the metal frame of the monitors isolation transformer (on the floor of the cab) and make sure there is a path to the metal frame that the monitor is in. there also should be a ground path to metal parts like the coin door.
If you have metal mounting plates on your joysticks, then they should also be in the ground path.
Don't confuse this with the ground loop that goes to your buttons and joystick switches. that is a completely seperate loop.
I wouldn't worry about grounding the computer, that should be done through the computers power cord.
If your motherboard blew after plugging in the jpac, I would look into what directly wire to that such as the switches and video.
It would also help to have better pictures that show all wiring.
You really need to verify how the jpac is wired.
