Need help wiring MH ballast

[Hobbzz]

I picked up a Coralvue 400w electronic ballast this weekend along with a spider reflector w/mogul base socket. Got a great deal so I figured I'd try it out. The ballast has two wires, one blue and one brown. The socket is already attached and grounded to the pendant, but it has three wires going to the ballast...one yellow, one green, and one black. I've tried google and RC and came up with nothing and I can't get to coralvue's site. Anyone know how to wire this ballast?

Generally your Black will be your Hot wire, Green will be ground, and Yellow / Whites are usually your Common wire.

That's correct.

I read in one post on RC that coralvue told someone that the ballast wires had no polarity. If that is true, then the blue (from ballast) could go to the black or yellow (from socket), and the brown (from ballast) could go to the other correct? Or am I still missing something?

Also the wires are already connected to the socket and one is grounded to the reflector. What do I do with the other end of the ground (green wire)? Ground it to the ballast? I've only done one other retro kit with MH and it was about 4 years ago, and it had very detailed instructions so you'll have to excuse me if these are some obvious questions.

Thanks for the help guys.

If your ballast only has 2 wire leading out to the socket, you don't need to worry about connecting the ground wire although the socket has one connected to it. Just snip the green wire on the ballast end of the socket wire and put a wire screw on it.


I'm unsure of how CoralVue ballasts are with the wire leading to the sockets, but ARO ballasts has 2 blue wires coming out and it doesn't matter which is which. This may be the same for the CoralVue.....

I've just upgraded to MH and went through this whole process 2 weeks ago and just passing along info I learned.... hope this helps.

Thanks. I didn't get a chance to call coralvue but I did email them so I'll see what they say.
