Have been charging at home since I took delivery July 2018, using a Nema 14/50 installed just for charging using the portable charger that comes the the M3. A week ago, I got a lot of messages over night about charging interrupted due to overheating at the box, and long story short, the charger plug had become loose and was about halfway out. I inspected and it looks like burn marks on the plug and also the box. I plugged it back in and have charged but a week later, I noticed while charging that it is only showing 15 amps, with max of 15 amps (15/15), not the 32 I have always gotten when charging. I'm going to call an electrician, but any ideas on what has happened? I checked my fuse box and all looks good.
Thanks for any input
