We went from summer to fall in one day here. On my list of to do's for winter is to investigate why the block heater is drawing more than 20 amps, when it used to draw 10. With age do they degrade and have more resistance? It had been tripping the inverter ckt it is on, so I plugged it directly in to shore power, and it cooked my 15 amp 12 gauge ext cord after 60 minutes. I can't see where it enters the block, but it is in the passenger side lower block area. I think I am going to have to get greasy on this one!
