Block heater plug not warming engine
My 96 F250 wouldn't start this morning. It's kinda cool outside and I left it plugged in overnight. Felt the plug connection and it was cold. I've noticed when unplugging in the past this connection is warm. This plug connection works and verified. Any ideas where to look ? GPR ? Block heater relay?

Check the resistance on the block heater cord .. the two flat prongs. It should be about 15 ohms. A while back mine did the same thing and it was a bad connection in the extention cord where it plugged into the block heater cord. I went and purchased a heavy duty extention and no problems since.

The plug terminal really looks shot. I'd like to replace it.
My thought process to do this is to cut the wire just below the prong terminal and replace it with same voltage found in Radio Shack/Home Depot.

Yeah they always seem to break at the plug Ive had to change mine several times now It's gotten to the point that if it happens again I will have to open the hood to plug it in LOL.
I bet it is your cord I have this cool little voltage detector it is the size of a pen all I do is point the detector at the cord plugged in and it beeps and flashes where there is power finds the break fast

I have my truck plugged in on a timer for four hours. Temp gauge reads cold before and after I turn the key. Normally, the factory gauge will read up in the normal range when plugged in for this amount of time.
I checked my plug ends; Truck plug read 14.6 Ohms; Extension cord reads 15.5 Ohms.
Am I correct in assuming I need a new plug end on the truck?
