What colored wires are coming out of the ballast?

Is there a sticker with a diagram for the wires?

 

[phatpharmer]

Theres 3 wires white,green,black theres no diagram but I notice it says wired for 347 volts what ever that means also I opened it and all the wires seem to hooked to the same colour wires hopefully this helps thx Phatpharmer

:confused2:

When you attached the plug, is it possible you attached the black/white to the wrong pins?

How are you testing this anyways, it has a bulb?

edit: Maybe that's why they stopped using it at work :laugh:

Can't think of what I'd do different :confused2: sounds like a bunk ballast. Goodluck with it!

Wait.. it has a ballast right? You don't just have a hood?

Does this light have an energy converting ballast?

A multitap ballist should have other wires not being used, somtimes the wire itself is marked with 120, 240, 480.
Here is a generic diagram that might help.
But all you need to do is take the 120v from the cord and hook it to the 120v wire tap of the transformer instead of the 347v tap.all other wires will be the same.
