Yes, I would check the output of the controller with a digital volt meter. Now it's my turn to say how I feel (pun intended) the heat;
I have the Gerbing Jacket, gloves, and socks. I have worn them under the Darien jacket WITHOUT the liner and it SUCKS the heat out. I now wear the Olympia jacket with liner and notice a HUGE difference! I wear almost nothing under the Gerbing jacket, nothing under my Gerbing gloves (duh) and a very thin sock under the Gerbing socks, and I'm here to tell you that it gets HOT, and yes, I do ride in some cold days down here in SC. It was 27 this morning when I went to work, two weeks ago it was 23 when I went riding all day.
I have the dual controller, and when I'm alone, I connect my socks by themselves (only on the coldest of days, and longest of rides, do I wear the heated socks), as my feet can get too toasty with them on with the jacket (good boots).
