'T' on charging cable flashes red.

[mnsweeps]

I used this charger in my garage for my Model 3 and Model Y. When I start charging I get 30 miles/hour .. after a few hours, I see the rate go down to 15 miles/hour. I have a similar 240v outlet and charger on the other side of the garage and thats works fine.

I went to check the charger and see the 'T' flashing red 4 times but charging continues at 15m/hour. Is this a grounding issue on that particular ground outlet?

OH MY GOD !!!

Sorry. Don't know what that means after all.

Four red flashes.

"Charging current is reduced
due to high temperature
detected in the wall plug"

Same happened to me with hpwc. It was because the wires inside the box were not torqued down enough. Same on the breaker as well.

You might have a loose connection in the outlet. Loose connections will make the outlet get hot.

Sounds like these people know what they are talking about. But please, please, PLEASE, don't try to fix this yourself UNLESS, you really, really, really know what you are doing. We don't want your last post here, to be your LAST POST.

This happened to my mobile connector, too. I would also see charging errors notifications on the screen. Tesla ended up replacing the unit under warranty.

This is because the mobile connector is ramping down the amperage available to the car. The car doesn't see it as an error because it's technically not an error to the car, the amperage is just lower.

You should have someone check your 14-50 socket to make sure everything is still tight. If possible try the mobile connector in another socket of the same type and start charging to see if it's the mobile connector.

Did that fix your issue or did you end up having an electrical issue at home?
