Just had my UMC + NEMA 14-50 replaced today. Schmelted the old one. It still worked, but clearly faulty.

When I went to get my tires rotated, I got replacement adapters for 14-50 and J1772.Just had my UMC + NEMA 14-50 replaced today. Schmelted the old one. It still worked, but clearly faulty.
Left is my original (U.S.) Signature vehicle J1772 Adapter.

Functional differences reported by Tesla:
- Better fit for the broad array of J1772 EVSEs in the marketplace.
Observed differences:
- P/N change from 1005617-00-A to 1005617-00-B.
- Newer one is shinier.
- Color change from gray to bluish gray.
- Triangle-with-exclamation icon next to the "CE" logic changed from yellow to white, and no longer has an inset black triangle.
... on it. I presume the original ends with "A". But that's just a guess as I don't have my original one.1014324-00-B
The J1772 versions have different TPNs (part numbers). I posted a picture in another thread.
As for the 14-50, BRB...
May be the best way is to forget about using UMC charging at 120V. Cut the end of the AC plug and wire to a Home Depot 14-50 plug.I had one of the newer 14-50 adapters too when mine was replaced. It just appears that over time, some UMC's are not making full contact and it's generating heat.

I was just pondering today- the UMC and cable sure does get hot - couldn't they make a bigger, thicker version that would stay cool?
Sure it would be more bulky, but I wouldn't mind that since it stays fixed in my garage 99% of the time (and I could still keep the current, more portable version for road trips...)
I would think the cost savings over time (in less wasted electricity) would add up! So surely that's worth something...
Correct me if I'm way off...
Sorry that my message was not clear. I meant to suggest cut the end of the male connector and wire with GenTran 50 Amp 4-prong Straight Blade Male Plug NEMA 14-50-DISCONTINUED-RJBP1450 at The Home Depot or Amazon.com: Camco® Power Cord Plugs with PowerGrip™: Automotivewhat? totally didn't understand that statement.
I lose 3 kW per day from vampire loads. UMC is irrelevant when it comes to kW lost.
^^^That might solve the melting problem, but not the UMC malfunction problem.
BTW, the old 14-50 adapter does have a part number that ends in A. The new ones have a B.
