Help - Truck Won't Take Charge after 2024.26.7 UPDATE (NOT the Software)

[JackCypher]

This did not happen with the update and my truck ¯\_(ツ)_/¯

..that is interesting...Does your app recommend "80% for daily driving"...mine does

yes

Came here to say this. He sounds like a lazy hack that couldn't be bothered to do it right. I'd make him fix it, but watch him like a hawk so he doesn't cut corners.

In his defense, he was using the wire that had already been installed as has been there for years for my 240 plug. I never discussed more or less as Electricity is NOT my thing but after reading this discussion over the last 12 hours I have a much better understanding of what is going on, thanks to you all.

Today, while sitting in the driveway but still on WiFi the Beast updated to 2024.26.7. Same day I was having my new Wall Charger 3 installed. Pulled her in, plugged her in and everything looked good but it stopped charging after a few moments and the charger light turned blue. Have played with it to with no luck so with Tesla Support closed I pulled out the Mobile Charger and was forced to plug it in to 120 and it did the SAME thing so it is not the wall charger.

Is there a way to reboot the Trucks computer and see if that clears up the problem...I am in sort of a bind without being able to charge and would appreciate any help you guys can render. THANKS

Update, powering off, waiting 3 minutes and touching the brake to activate did not work.

Were you nearby when the update occurred? I am almost wondering if one of the contactors (loud power switch noise you'll hear) stayed opened, thus not completing the circuit. Good luck! Hope everything works out.

What a crazy 24 hours! In a way, I owe you all an apology for initially pointing the finger at the software. After twenty-four hours of troubleshooting, I finally figured out the cause during a brainstorming session with an industrial-sized Wrangler Iced Tea (15 oz of cheap vodka with a shot of Arizona Tea… or is it the other way around?) and my iPhone.

I spent time reading all of your kind comments and talking with Tesla Techs. Everything checked out—the Wall Connector, Mobile Connector, removal of scheduling from both of our iPhones, proper firmware, and Tesla Electric, which scheduled the 12-6 AM charging. We should have been able to override it at any time, but something wasn’t adding up. That’s when I noticed a very important icon right next to the Tesla App… drum roll, please… Tessie.

Yup, Tessie was holding us to the 12-6 AM charging time. Once I disabled that, guess what? Life is good again.

I came to you first because there’s a wealth of EV experience in this community, and I’m still a newbie to this technology. Over the past day, I’ve become a quick study, thanks to all of your suggestions and help. But in the end, it was a third-party app that had everything mixed up. Truly a learning experience.

That is not a defense of your electrician.

The install is not code compliant until the Wall Connector is properly configured for the size of the circuit its installed on.

MAJOR goof by your electrician for which there is NO defense or excuse. Wiring a Wall Connector is one of the simplest jobs an electrician can do. He obviously doesn't have a clue.

Can't argue with that, we will have a talk and the only way to make it right is to pull new #6 wire with 60A breakers...he only did this as a service call and it is true, you get what you pay for. Plus, I am not confident with software control, only, over that circuit. It should be built to handle the maximum pull.

Geeze, can we put away the pitchforks and torches?

Wiring a Wall Connector in place of an existing outlet is easy and they did that.
Knowing Wall Connectors can pull up 48A (unless they are an older 80A version) is something that no one has a clue about initially. Further, the previous generation WC defaulted to 12A. So an as-provided install used to be safe.
For today's Wi-Fi enabled configurable devices, is the onus on the average electrician or the homeowner for setup? (Excluding turn key Tesla Certified installers).
Beyond hot tubs, is there any other equipment with ampacity configuration, let alone 4x range of current draw?

Should they have at least skimmed the install guide and checked the current draw? Yeah.
Does not doing that make them a hack? No (unless it was originally a 14-50 outlet on a 40A circuit, that's a problem hidden by the Mobile Connector's 32A limit (well, recent versions of MC, older ones would have allowed 40A continuous).

Setting the WC to a 40A breaker makes it right (just not as fast to charge as a 60A breaker).

Pulling a new 60A circuit pushes potential issues upstream as the panel loading will need to be checked.

Software is the only thing that causes the vehicle to honor the WC's published charge limit.

Knowing Wall Connectors can pull up 48A (unless they are an older 80A version) is something that no one has a clue about initially.

I recall an episode of “House, M.D.” where our doctor was discussing the exact milliliters of venom from a specific snake. An exasperated med student asked “do you expect us to know the amount of venom from every snake??”

“Of course not,” House replied. “Unless, of course, you want your patients to live, then it might be important information to know.”

It is gross negligence for a professional electrician to hard-wire a device to an undersized circuit. If he “didn’t know” then he should have taken the time to find out, or refused the job.

Didn't I say that?

Should they have at least skimmed the install guide and checked the current draw? Yeah.

We don't know the background. Was it a quoted job that specified installation of a 60A EVSE? Or was it a "hey, could you swap this charge connector in for my existing one"?

People mess up. Sometimes you don't know what you don't know. Can't that be separated from their entire body of work/ character?

House had patients die (cardiac arrest then revived), did that make him a hack?

Incorrect.

The Wall Connector is designed to be safely wired to any size circuit. It just needs to be configured for the right circuit size. The first versions had dip switches to configure for circuit size, now it's a software configuration, either way is more than sufficient because you cannot accidently configure it without knowing. I mean, someone could sleepwalk and loosen all the breaker wire connections too, we don't have hardware locks on our breaker panels because we don't need them.

Even in the worst-case scenario, where unqualified people are configuring it improperly, as long as the breaker is properly sized for the wire gauge, the breaker will protect the circuit from excessive draw. That is the failsafe against improper configuration.

But I agree that a higher power charging solution is better than a lower power, and if you have the available amperage, that's the way to go. The reason the Wall Connector has configurable outputs is so it can be installed even in cases where the existing electrical service is insufficient for a bigger circuit. It's very versatile in so many ways.

Having seen what your electrician is capable of, I would have trouble trusting him to upgrade the circuit. It seems like he's on drugs. I mean, I don't know how else to explain how careless he was when he wired the Wall Connector to a circuit without checking the amp rating of the Wall Connector. It's so basic it just boggles the mind, what he was thinking? That's why I think he must be high on drugs or something.
