Dead Charger? Help

Dead Charger! Delta Q OEM
Not sure what happened but I plugged my FThink in and it popped the gfi. Unplugged, checked fuses, flipped service switch off/on, plugged back in and popped the gfi again, fuses are still good (under seat). Left town for a week or so can back plugged in (didn’t pop gfi) but the plug emblem didn’t show up on screen and no lights came on to the charger.

Any thoughts?
Are these chargers rebuildable?
Anybody on this forum have a charger for sale?
THANKS

Try a non-gfi circuit.
Make sure ac is getting to charger.
If truely dead, used ones show up from time to time.
