I would appreciate someone helping me wire this old Magnetek ballast. Cat. No. 1110-245-sc-tc. It is a 175 watt metal halide. The diagram shows this:
277v. Black wire
120v BL/Yel wire
white from ballast joining white coming from bulb
red to bulb

Now, my interpretation of this is, the black does not connect to anything, the Bl/Yel goes to the AC plug,the white to bulb and on to AC plug, the red to other side of bulb.

Does this sound correct?
If I could figure out how, I would attach a drawing of diagram. Thanks.
