Wall mounted charger

[daddyfish1982]

Moved into new house with existing home charger TPN: 1011831-99-B and TSN: T13A0002269. My 2021 Tesla model S will not charge on the high power wall connector. Previous owner of the home had an older model S and says the charger worked fine for him for 5 years. What must I do to get it to work?

I had a problem charging on a Gen 2 wall connector. I never solved it because it was not my wall connector. Is it on a 100 AMP breakers? If it would have been my wall connector I would have tried setting the wall connector at 48 AMPs and try that.

PS - The charger is actually in the vehicle.

Probably incompatible with MCU2:

HPWC no longer charging after Infotainment Upgrade

I've got an V1 HPWC that charges at 80 amps on my dual charger P85D. It worked in a bulletproof fashion for many years. I brought the car in to replace a leaky LCD screen and they convinced me that the Infotainment Upgrade made more sense, so I did it. However, ever since I brought it home...

Link to what beatle is referring to. I thought it was only with Gen 1 wall connectors.

I'd not heard of any compatibility issues with any UMC, only early HPWCs and MCU2. FWIW, I have MCU2 and I use a gen1 UMC connected to a 14-50 receptacle in my garage to charge at 40A.

Probably incompatible with MCU2:

I am pretty sure it's this. There is a known incompatibility of old wall connectors with the newer vehicles. Some kind of communication signal mismatch that Tesla never worked out. Their fix was to replace the old Gen1 wall connectors with Gen2 wall connectors. So now I guess that would be the Gen3 (I'm sorry) since they don't sell the Gen2 anymore.

Thank you for the tip! The dip switches fixed it. All set now!

that was going to be my suggestion.....I was on 100a panel and had to charge at 40a.....I upgraded panel to 200a and changed dip setting to allow for 48 a charging...works fine......since you have 100a, you did the right thing also, the Gen 2 charger that has the NEMA 14-50 plug has known issues....will cut down from 40a to 30a when it senses heat in the cable or connection.....Tesla admitted they were bad and gave me new hard wired connector.
