Doug, what's with the extension cord?
Extension cord leads to an under-hood multi-outlet box that feeds a 500 watt engine block heater; a 125 watt oil pan heater; a 75 watt transmission pan heater; a battery trickle charger; and a 900 watt electric interior heater.
You're way over east in the Carolinas if I recall correctly, so, let's see, if you notice your lights flickering at about 9:30 am (that would be 5:30 am Alaska time) it's because my outdoor timer just cycled on and began the warming up process on my car.
You may remember (or have heard of) the great East Coast Blackout of 1965? Yeah, that was me... I tried to plug in TWO cars at the same time...
