arcade wiring question (jpac) please help...
ed12:
that in pic #2 is the degauss coil..
it should not hook to the transformer
but rather through a ptc/relay on the monitor.
the ac main's should go from the transformer to the monitor
as for grounding
ground to transformer/then monitor/then coin door/then control panel,
now days we tie them all back seperate
to a common binding post..
as a rule
1=hot black for 120vac brown 220vac
2=ground green for 120vac yellos with a green tracer 220vac
3=return white for 120 vac blue 220vac
sec. side of tranformer goes to monitor 120 vac in,tag a chassic ground here
chk to make sur u are tieing the ground of the interface to ac hot,that6 will def give your mobo a headache..

i think you are right about that being the degauss coil or something, since it goes around the monitor and there is one wire that goes across the back of the screen thats hooked up into the back of the monitor. i have pics of it below , where i wrote "degauss coil?" thats the wire thats connected to go across the back of the monitor.
some more pics.

ed. how do i ground all these things? do i solder a wire to it or something and where ? like for instance on the transfomer where would i put a ground wire, on the monitor where should the wire go? on the coin door where should the wire go, on the coin mech itself or on the metal plate its attached to? since im pretty sure there is a ground wire connected to it with the power going to either the jamma harness or the gameboard powersupply, do i attach the ground loop to that ground wire? ahh im so confused.
and on the control panel all wires have a ground going to the jamma harness, do i hook that wire up to the ground of the plug also?
having all those daisy chained to the wall plug ground/earth would do the job?
doing it right and making sure its done correctly is my concern.
thanks for the help sofar guys. sorry im asking so much questions i just dont know anything about this kinda stuff, now if it was computers or somethng like that it would have been easy.

hi
man i gotta slow down when i type :):)
to the ground,it's easy
if u do not have a common ground point ? u make your own ie a binding post >bolt and nut here< or
just bring a ground from the metal chassic of the monitor,and 1 from the coin door,and 1 from control panel down to the transformer,then the ground of your line input >green< will tie to that point..all will be fully earth grounded in your cab..just make sure any where u make ground to remove all paint and varnish.
the metal brad in pic #1 is your picture tube :static: ground
leave it intact do not disturb it..it act's as a high voltage static drain
the black cable wrapping the picture tube in picture #2 is the degauss coil
i will go on a limb here and ask if this is where the 2 red wire's come from ?
pic #3 is the foucs lead,and or your picture tube ground return :leave it alone:.
u olny need to ground to the metal chassic of the monitor

yes ed slow down u have to remember im a total newbie at this.
there is no common ground yet, id have to remove the current power lead, and get one that has 3 wires cause this one just has 2.
hook the same 2 wires up to the transfomer and the 3rd wire that would be ground id have to daisy chain to where i want things grounded?
"the black cable wrapping the picture tube in picture #2 is the degauss coil

yes thats correct, it goes all around the monitor.
the control panel is made out of wood not metal. so do have to attach a ground wire to the wire of the ground that goes to the jamma harness or not?
also the coin door is not a door. its just a coin mech, with a opening at the bottem that has a box for the coins.
only the front part of the coin mech is made from metal , but there is alot of plastic on it.
can i attach a ground wire to one of the monitors bolts, will that work? to ground. like u see in the right hand corner here is the bolt http://i51.tinypic.com/212vl8h.jpg
or do u mean this on the right, the control board http://i51.tinypic.com/24pib8i.jpg
so what im asking the metal chassis is this the part where the monitor is screwed down into the cabinet with bolts?
if i ground all that stuff. it would be all good to plug in the jpac?
sorry again for all the stupid questions. but i always play things safe rather than messing stuff up and then crying cause i was not patient.
mgb:
The answer has been given a few times now.
1) Change your power cord to one that has a ground (3rd wire), in order to have a ground path (assuming you outlets are grounded.
2)in the cabinet, put a ground lug on that ground wire
3) run a ground cable (14 gauge) form each of the following locations, to that lug and attach.
a) The metal frame of the isolation transformer
b) the coin door
c) the metal frame that holds the monitor control board (chassis). its mounted on the side wall of the cab
d) one f the bolts that hold the monitor to the cabinet
e) any metal controls on the control panel.
4) Verify the wiring of your jpac. You have asked for help but you have refused to verify some of what you've been asked. When helping someone troubleshoot a problem, there are questions that have to be answered in order to figure out what is going on, but you have not been helpful in answering those questions.
You've been given th answers, now you have some work to do to get it going
