Charge Fault with two different at-home chargers (Tesla and Charge point)

[desiderata2001]

I have read everything I can find on the subject without resolution (including Reddit).

I have a 14-50 outlet that I use with the Ford mobile charger, and it works fine, no issues at all.

I traded my Tesla for the Lightning and already had a Gen 3 Wall charger for the Tesla. I never had an issue charging the Tesla (or other electric cars) but as soon as I hooked up my Lightning I got a charge fault. (Red ring only one time). I read that Ford can be a little fussier. I checked all wiring gauges, breakers, etc. and everything seems fine.

I sold my Tesla charger and got a Charge Point hardwired and hooked it up with 6-3 and a 60amp breaker (non GFCI). No issues with anything on the charger but still getting Charge Fault with Lightning. I have noticed one thing, when I first plug in and then go to the Ford Pass App and look at energy, it starts off with 1 kwh and goes up to 8kwh and then back down to 1kwh and then back up several times until it does the charge fault.

I have never had any issues charging anywhere (DC fast charging, etc.) but at my house. I am starting to suspect something is awry with my electrical panel but wanted to check here first. I have deleted my preferred charge times just in case.

I am not electrician, but I know enough to do simple installs.

Any guidance would be appreciated.

It is possible you are getting low voltage that the Lightning doesn't like. Perhaps when you were drawing 30 amps or so with the Ford mobile charger you were still maintaining about 240 volts, with the higher demand of 40-50 amps perhaps the voltage at the outlet has dropped enough for the truck to refuse it.
You can easily test 120 volt circuits inexpensively with the following device at a plug-in near the charger that may provide a clue. I am hoping if the 240 voltage drop is the issue, you will see a measurable drop on a 120 plug when the charger cycles on/off trying to charge the truck.

Low voltage to your 240 volt wall charger plug could be caused by several things, so before chasing that rabbit it would be good to gather more info.

Low voltage cannot cause problems. You can supply 120V to a 240V EVSE and it will charge. There is a problem with the charger in his truck.

What led me down that path was the OP's experience with the Truck taking juice from a Ford mobile charger.

It could be the truck. I could DCFC, but level 2 charging would always fault. Here is the thread of my experience and what module was replaced on the truck. https://www.f150lightningforum.com/...rging-with-autel-50a-fix-replace-sobdm.21241/

I hope this helps.

I read your post before, but I have used other level 2 chargers successfully and that's why I was thinking it was something with my charger (or electrical panel), but I will call service today and see what codes they are seeing.

I am also going to throw a meter on it tonight just to see what I am getting.

Hoping you aren't running the 14-50 plug on a 60amp breaker..... ;-)

I've had charge issues on my 2023. I've had to do a 12v reset to reset the onboard charger a few times (and it worked). I would get the red ring of death on all EVSEs until I did the reset. I didn't however test it on the Ford Mobile Charger but it wouldn't work on the Ford charger at the dealer either. Ford eventually had to replace the onboard charger since the 12v reset wouldn't work anymore.

I'd try the 12v reset first. Then if it continues, book it in at the dealer.

No, the 14-50 is on a 50 amp. I will give the reset a try. Thank you.
