    here ya go, this should help

    http://www.advancetransformer.com/eC...0241612151.pdf

    Looking at the diagram, looks pretty straight forward, like regular M57's and M58's:

    live ( 120v ) goes to ballast at 120v (110v) pin.
    com goes to lamp, ( which may connect on the ballast and ballast out to bulb )
    other side of lamp goes to cap
    other side of cap goes to ballast.


    be very very careful, you are not only playing with 110v ac but with a coil ballast which outputs thousands of volts, Hope you know what you are doing as those jolts are not pleasant!

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    to Aquaria Canada

    you should have two cords, one that connects to the transformer ( ballast ) and has a wall plug in on the other end. and another cord to connects the ballast to the mogul.

    if this doesn't help, maybe you could post a pic or two of your parts??


    just to add to liv's warning, be very careful even when the unit is unplugged. the capacitor can / will hold a charge for a long time after the unit has been unplugged and can severely shock you. :b13:

    absolutely, the spark coming out of there is amazingly big.. like very dangerous.

    I unloaded one once, the spark must of been 2foot long.. and them some.

    the 'lamp' in the digram is the mogul ( where the bulb is attached ).

    if you want, you can email your pics and i will post them for you :b15:

    okay from what I'm gathering here you have a ballast that is disassembled??
    do you have a proper case for it?
    from the questions your asking, do you really want to mess with this. I'm in no way trying to be rude but you have the potential to electrocute yourself or cause an electrical fire. were did you get this ballast.
    because you can buy complete kits from any HYDROPONICS store or online
    or, see if someone here with ''experience'' will drop by.

    can you post a pic of your components.. i'll take a look.
    Johnny is right that it will require some kind of steel box / enclosure to put this thing in and well grounded.

    also keep in mind that the lenght of the ballast to bulb should be around 96" maximum to have a reliable ignition. some may go further.. but rule of thumb is 96"
