I changed my batteries and everything has been fine. Till last night, it was -14 degrees and it was having trouble starting and I had her plugged in. Once she started and got warmed up everything was fine.
Just curious if the motor is just that cold or is there something else going on?
If you have it plugged in for 3 to 4 hours at least, it should fire right up, right down to -20, -30 or maybe less.
The heater cord plug on my truck has been a real PITA for cracked wire insulation right at the plug hanging out the front bumper. When the insulation cracks, moisture gets in there and eats the copper wiring like mad. Unless you inspect the cord closely, you'll never notice a problem, unless you notice an arc at the point of breached insulation or a GFI outlet keeps tripping. I replaced the male cord end and fixed mine. It was just like changing the cord end on an extension cord.
I began to keep an outlet tester in the truck and would watch for a spark when pluggin it in, slight dimming of building lights, a sound from the block heater element perkulating or any other indication that it was working.
