Electrical Question

I am very coach/electrical savvy but this has be stumped. The shore power cord on my 17 MA when plugged in, the plug gets hot where the ground is. The rest of the plug and the cord is cool. It was hot with only pulling 3 amps. I suspect a bad connection in the plug but its a sealed unit so I don't see how to take it apart to check.

Any other ideas?

Can you plug in somewhere else? It could be the power source.

That is what I suspect. I think its in the shore power plug but it looks sealed and doesn't come apart. I think if it was in the real or switch the cord would be warm which its not

Its plugged into my shop that is 2 years old. I weld all the time off the same outlet and it doesn't get warm.

Good thought though

As judgebobk said, if you try it at a different outlet, and it does the same, the plug could be defective. You can cut it off and install a new one.

I have a progressive ems on it and it show 1 amp and 3 amps. Everything looks good which is why I am stumped. I am pretty sure its the coach plug that has a bad connection in it. I was hoping maybe someone else had experienced the same thing

I had a disproportionate load problem and it was my power reel that had to be replaced when the coach was new. I don't understand why your center post would be warm unless there is current going through it.
Could there be a short in your wall receptacle?

I have had it plugged in to multiple outlets with the same result

I like these things to run cool so any warmth seems hot to me. I checked it with a thermometer and its at 98deg but the rest of the plug is 81 deg
