By "turn over" do you mean the starter cranks the engine but it won't start or that it doesn't crank at all?

Sounds like you disturbed some starter wires somewhere.

Re: problem starting Sign In

Ok...lets try again. Currently busy so i typed it fast. I tested the oil pan heater. No coninuity to ground and reading about 25 ohms hot to neutral. i tried a different extension cord that i was using for my truck and it still instantly tripped the gfci. I know that the gfci is fine and in perfect working condition. Im not reading a shortwhen i test the oil pan heater. What would cause it to read fine but trip instantly. Also when i plug in the oil pan heater it arcs out inside the plug which would seem like a short. Any ideas??

Does it trip it when it's unplugged?

Whenever the oil pan heater plug is plugged into the cord it arcs and trips the gfci. No matter what i cant get the oil pan heater on the car to work with the gfci but my truck works fine. Also i had the car plugged in a couple days ago and it was working fine.

It sounds pretty clear that the heater is shorted.

Agree after all this seems your Ground Fault for power is doing it's job as it should for outdoor and other home wiring. If this block heater is just installed in a so called freeze plug or port on the engine it's drawing too much or shorted.


Just curious by subject line. Why is this car so difficult to start without a heater? Are temps and location where you leave this car that low still?

Re: problem starting Sign In

Confused - a block heater powered by "house current" shouldn't have diddle to do with the car really except a warmer engine naturally would crank AND start faster in extreme cold. I don't see the connection between a failed block heater and why the engine doesn't crank.


Not cranking is the problem so lets forget the 110v problem as I don't think it has anything to do with the car as the ones I know are just as named, heaters that shouldn't require a car to test if the thing was still uninstalled......

Re: problem starting Sign In

He has 2 different issues Tom. First he had the heater tripping the breaker but when he tried to remove it, something happened to the starter circuit.
