I have the 12v Trouble Outlet for the Trouble Light in my glove box. it is not attached to any power or ground. So, I took it out and attached one end to the negative terminal on the battery and 1 to the power terminal on the battery and I get no power to the outlet (I tried to plug in a simple 6v device I had sitting around). I switched them around and still no joy. What gives? Is it that simple as providing power and ground to each terminal end on the plug? or am I missing something? If it is that easy, why no juice to the device I plugged in?
