Well initially when first turned on the amp draw would be 6.2. After the pad had cycled on for a while and heated up the circuit, the ciggy plug voltage would drop current consumption to the low 4 range. With The powerpoles the amp draw started at 6.8 and stayed at 6.8.
Perhaps this extra 2.6 amps was the straw which broke the camels back. The side of the pad which failed is the one which sees more abuse, and honestly half the pad is still good enough, but it has not been very chilly, as far as chilly goes.
I'll probably dissect my current pad after I decide on a replacement. I might go with the same make and model and just call it 30 dollars per winter and hope it lasts 3 years.
I wonder If I can retask the controller for something else.
