    8.6kW UMC Gen 2 Charging on SR+ with 277Vac!

    I decided to update the wiring at my work where I do most of my charging. I was using a 30A 277V circuit, with a NEMA L7-30 to NEMA 14-30 pigtail, connected to my UMC with 14-30 adapter. I was pretty happy with the speed, 6.4kW for only 24 amps is pretty good! But that wasn't enough, plus I...

    16A Blue Adaptor

    HI All, Got the Tesla on the way, and I'm just trying to wrap my head around the charging options for home. I probably only do about 50 km at most on a typical day. My plan was to go for the caravan type plug. Tesla call it a 16A Blue Adaptor on their page, but in other threads its referred to...

    Tesla Gen1 mobile connector wall side wiring diagram

    Hi I bought from Ebay a gen1 UMC and didn’t notice that its wall end adapter is cut. So now as I'm far away from the US and received it I need to figure out how to refurbish it. I see there are two thick red wires which are L(+), two thick black which are N(-) and green-yellow which is G...

    Granny charger options?

    Tongue in cheek 'not for me' question... Sis has just picked up a Corsa-e, which I look forward to seeing eventually. However it doesn't come with a granny charger of any kind! When they are eventually allowed to visit the other parts of the family, they will absolutely need one if they take...

    Need an UMC - Mobile Connector with 5-15, 6-50 and 14-50

    My UMC died (seven flashes) now I need a replacement. I see Tesla offers the 32A that ships with new cars for $275 and I would need to buy adapters - 14-50, 6-50 and 14-50 ($380). So can anyone do better? PM if you have what I need or close to it.

    [UMC] Handle Temperature High error

    Woke up this morning to a half-charged car and a 'Handle Temperature High' warning and the charge rate restricted to 5amp. There is no debris in the charge port, but looks like one of the pins is damaged. I've scheduled the earliest service I could, but that's not until 28th Jan. As I'm...

    Mobile connector died

    It looks like my 7 month old gen 2 UMC has died. I get no lights on it and the car doesn't recognize that it is plugged in. I have another umc that I keep in the car and it works perfectly fine plugged into the same outlet. I swapped around the 14-50 adapters and it seems to be the umc. I've...

    ATTN Y owners: easy Qs I’ve never seen answers for

    For those who has their Ys, just some simple questions: What UMC did your Y come with? Nema 5-15 or 14-50? How many amps or kw is it? Can you exchange the ends or is it hard wired for whatever plug it came with? (Is it adaptable?) Can you post the Monroney Sticker (appropriately...

    Looking For UMC Gen I Tesla 6-50 Adapter

    Needs to work perfectly and be well-cared for. No issues or quirks. PM me to discuss price but I'm not looking to pay new prices for a used adapter because I'll go buy a new one if this isn't going to save much money. I'm looking for lowest offered price under $30 via PM.

    Hello! I'm an almost owner of a pre-owned 2014 MS 60 that I've purchase and will be picking up in Orlando soon. It has 41k on it and as I have not spoken with a Delivery Advisor yet, I have no idea whether or not the UMC is in the car and will be included. So I have questions that maybe some...

    Strange UMC behavior. Memory loss?

    Hi all. French MS85, december 2014, 140 000 km, UMC replaced circa 1 year ago under warranty. For 3-4 months, my car has strange behaviors, one at a time or several together, following a (to me) random pattern: 1- At startup, Spotify disconnected from any account (personal or Tesla). Check...

    Problem charging at 110V on Tesla UMC (Red T)

    Came up to my parents' cabin with my Model 3 (first road trip!). I was hoping to charge the car using a standard 110V outlet and the Tesla provided UMC (universal mobile charger). When I plug in the UMC, the TESLA letters light up green, but when i plug the UMC into the car, I hear some clicking...

    Car won’t charge on HPWCs/UMC, says check Wall Power

    Posting this here, even though Model X, since it’s really not X specific. Just after loading 2018.20, this happened. Tesla doesn’t think it’s firmware dependent..... I have two load-sharing HPWCs, and a backup 14-50 (see sig). On the first drive after loading 2018.20, and returning home...

    Charge port door sticking?

    3/17 Model S, today I had an issue with my charge port door not opening. Clicking the HPWC button initiates a 'click' but nothing happened with the door even after several tries. Unlocked car with all handles out, same thing, tried in mobile app, same thing, tried on MCU, same thing. Applying...

    Suspended UMC setup

    My garage is in the basement and if I'm not good about cleaning up the leaves in my trenched driveway then then can clog up the storm drain if it rains hard. Once a year or so I end up with some water in my garage — never fun. After several months of charging via 120V on an extension cord, I...

    Home Charging Issue w/Gen 2 UMC

    Just curious if anyone else is having the same issue that we're experiencing with our 2nd Gen UMC. We took possession of our M3 almost a month ago and haven't had to charge at home until very recently. When we plug the 2nd Gen UMC into a traditional 120V outlet (GFI), it trips the circuit...

    Charging Non Tesla EV with Tesla UMC

    FYI: Teardown of busted UMC

    I had a busted UMC lying around that I salvaged the cord from for another project. Left with a useless UMC box, I decided to open it up and take a look around. This particular UMC met its demise by having the cord forcibly pulled out of the UMC box while actively charging. The metal and...

    Building NEMA 6-20P to NEMA 5-20R Adapter

    Hardwire a 14-50 plug to a UMC

    HPWC/UMC Charger Plug Case?

    Anyone seen any protection for the charger plug on the HPWC/UMC? I've rubbed mine on the concrete once or twice when coiling/uncoiling in the garage and hate to see it get even the smallest of scratches! Anyone come across any kind of plastic, silicone or rubber sleeve case for it?
