Hey Tim,
Did you buy this new or use. or was it a gift? I'm asking because you should know the system. Did you get the bulb, socket, reflector and ballast. The light bulb needs to match the ballast rating.ie: 70w,100w,250w ex.and the type of bulb hps or mh/ both. You should check this before hooking up wires.
Like you said you don't want to burn anything down.
I know money is always an issue, but this is an investment.
I will be using 6-8 (4-6 daylight 6500k)(2-4 soft white 2700) cfl's for veg and my hps system for flow. this will be about 3 months from clone to buds. ( i hope)
This is timly.
