Yellow light appears when I use the 240V outlet

Hi, everyone!
My charger gets a yellow light when I use the 240V outlet.
I found the ground wire wasn't connected.
I had a dealer replace the faulty cable, but the new one also has the same issue.
I tested it with the 120V one and I had no issues.
What could be the cause?

It sounds like you might have a similar issue to mine. My OEM charger started showing problems and wouldn’t work properly on a 240V outlet, even after reporting it to the dealer. Since you mentioned the ground wire wasn’t connected, that could definitely be causing issues...and since your 120V charger works fine, it seems like the 240V setup might have a deeper issue, possibly with the wiring or the charger itself..

Mine did this. I found that the plug in the end of the charger had come loose and was not making good contact. After pushing it in, it worked fine.

I found the same thing, when I "replugged" the 240v adapter the amber light went away and was replaced by a Blue light.

A tripped GFCI can also prevent the charger from functioning properly. Check for any tripped GFCIs in your home's electrical panel.

I had a similar thing happen when I turned off the 120V outlets in my garage. For some unknown reason, the 220V charger went to yellow. When I turned it off and then back on via the circuit breaker panel, it was happy. I guess you could unplug and plug it back in and it should be the same.
