Unable to charge, breaker trips

[chl]

I’ve had my truck since October 2022. I have never had any issues with my Ford charge station pro or charging my truck Other ways. This evening I noticed a charge fault. Because I’ve read all the threads I decided to turn off the breaker for the charge station and then turn it back on and try again. This also caused a fault. I then took my Mobile charger and tried to charge. I again had a fault on the mobile charger. This caused the breaker for the plug to fault. I decided to unhook the 12 V battery on the truck and then try again. Still every time I plug in the charge station pro or mobile charger. There is a quick breaker trip or fault. I turned the charge station pro down to 6 A, again same exact situation. Please help if you have any ideas. Thank you

Sounds like the on-board (in the Lightning) charge circuitry has an issue.
But you can charge at other locations with different EVSE's?

It is very unlikely the FCSP and the FMobil would both fail which suggests the Lightning - but if you can charge other places, then it must be some electrical issue in your service panel perhaps?

It seems like if there was a problem with your service or service panel, you'd notice other problems with other electrical devices.

If somehow one of the hot feeds got switched with the neutral from your utility - been know to happen after a power outage when sub-contractors do the work to restore power - that might do it - but you would have things that use 120V getting 240V and blowing up in your house if that were the case. Heaven forbid.

If the neutral came loose in your panel, there'd be no 120V in your house. If one of the hots came loose but not the other, you could see reduced voltage at the EVSEs - but that would not explain why the FMobil wouldn't work on a powered 120V outlet, unless half of your 120V outlets aren't working - the service panel I assume is split phase so half the breakers more or less are on each hot from the utility.

If the Lightning will charge at other locations then it is a real mystery to me wtf is going on.

If you look at the fault indication table for the FMobil it might tell you something:

He was able to DC fast charge but AC charging at home failed with 2 EVSEs. That points to an issue in the truck with the onboard built in truck charger. .

Agree, I think It’s pretty clearly an on board AC charging issue and nothing to do with my electrical system of my house.

Yeah, must be.
AC L2 charging relies on the on-board circuitry working properly (AC-DC converter etc.)
DC charging bypasses that circuitry.

Tough, but "should be a simple repair" (famous last words?), easier than Apollo 13 anyway.
