Engine block heater plug seems to spark when plugging in extension cord
So it's finally getting cold here in Wisconsin and decided to plug in the block heater yesterday night. When I plugged in the cord it seemed to make that "sparking" type sound. Didn't see a spark but quickly unplugged it and tried again. Same thing. I unplugged the cord and the extension cord did have a burning sensation, but the plug on the truck i couldn't smell anything. Decided to try and look it over today. Tried a different extension cord and had the same result. Looked over the wiring and nothing seems cut. I did do a resistance test on the 3 wires that go into the plug on the truck and it seems i have 15 ohms resistance between the common and the neutral wire.
After doing some research it appears that should be normal. Can someone please do a Resistance test between those two wires on their factory plug and let me know if they have that as well?
Hopefully their isn't a wiring problem on it. I'm scared to keep it plugged in. I'm not sure if it'll start a fire or if it could be just because the block heater is getting energized and it's doing that just because it hasn't been used for a long time.
Only major thing that was done since the last time i used the block heater was a full EGR delete. I'm not sure if that has something to do with it or not, but i do believe that the block heater warms the coolant, and not the block. Anyone with the full EGR delete using their block heater and it's working successfully??
