My ex-wife gave me her broken EV charger that I diagnosed:
Water or debris got on the dated 2016 control board letting some of the smoke out. Washing with isopropyl alcohol had no effect. This portable, 120-240 VAC, charging EVSE is no long made and a replacement will cost ~$250.
I will gut it and use these eBay parts to rebuild:
The only technical question is whether the AVC2 at 120 VAC will signal the EV to only draw 12 A. It should be fine at a 240 VAC. The EVSE normally tells the car the current limit by the width of a square wave on the pilot pin signal.
"Some assembly is required."
