Block heater......
Just came in from 6 hours of snow plowing with my 04 f350 and I get home pull her into the garage to drop the plow and get her ready for bed. So the truck has been running for about 5-6 hours straight, I went to plug in the block heater cuz its gonna be pretty cold here tonight, and the gfi trips. Now the weird thing is it has NEVER done this before. I have a 20 amp service just for my block heater. Could it be that the motor being as hot as it is, the block heater doesn't need or want to be plugged in
Any help would be greatly appreciated.

Try to dry out the plug ends. do the easy one first and see
if that helps.If not your going to be reaching up on top of the starter
to get at the engine side plug. If this turns out to be the problem
be sure to add a little dielectric grease to the plug to keep it dry.
If not get you handy DMM out and set on resistance in the high M Ohm
or auto range and you should not get any reading like it's open. However if you
do then you have a bad element. Pin hole leak to the water in the block.
You should see 3 terminals one is ground the others are power
The way you hook it up is one lead to one of the power terminals and one
to the engine for a ground. also check the 2 terminals to each other you
should see about 10 Ohms also check the ground one to the block
and that should be around 0. More than likely it just wet or a bad cord.
you can check the cord the same way just un plug it from the heater and
probe it to ground and it should show open.
If you need more help just ask.
