I got an electrician to change my level 1 charger from Japanese pins to 15amp Australian pins to make charging more convenient. It charges, but much slower than I expected. Eg, After a few hours charging I was expecting about 6% an hour from the 15 amp socket, and instead got about 3.8%. The EVSE control box's indicator lights start off normal, but a few seconds after starting to charge, all three start flashing. The manual says this means the control box thinks the plug top is overheating, or it just can't detect the temperature, and so is limiting current as a safety measure. Was there a temperature sensor in the Japanese plug top that was wired into the control box? Has anyone else had a problem like this?
