so i have recently inherited an 1000 watt mh lighting system. The only problem is that i have no clue how to wire the darn thing.
There are four wires that come out of the ballast. One reads LAMP, the other reads 120V and the last two read COM. I have both the lamp and the power cable that need to be wired together to the ballast.
(also, i have a timer, although i do not need to use it, unless it is mandatory to use with the ballast)
