need a wiring diagram for a 150 watt coralife M/H

I was taking apart my light system to change an actinic bulb,and there is one black wire for the main daylight,left(must have pulled loose)
The fan comes on when the balast is turned on,but no light.The black wire in question has no voltage when powered on,however when you turn the balast off,now there is 120v.
Could this be a ground?If so,does it get grounded to the housing of the light?Or possibly one of the brackets for a LED moonlight?
Any help would be appreciated.
Thanks a lot,Pete

What are the colors of the other wires....in conventional house wiring, black is the "hot" wire.

Also see if you can go to their website and find the info or contact their customer service department.

There is three wires coming in from the wire into the light housing,On just the M/H daylight.Two of which are black,one of the black wires is the constant,the other is the alternate.The daylight was working just fine,until I was trying to move the internal balast for the actinics,and then there was the extra black wire that was HOT when the switch was off,and than nothing(.008v) when the switch turned on.
I've been searching the internet all afternoon to find a wiring diagram,but no luck.It would look like the wire should be grounded to something,but nowhere is there something to ground to.If I grounded to the housing,that would make the housing HOT everytime the light was switched off,no?I am baffled/clueless so any help is greatly appreciated.
So long,Pete
