Trying to fix a gen 1 mobile charger

[mudfud]

My gen 1 EVSE from my model S bought sept 2014, is working about half time. It signals red and sometimes starts to work with a replug or a whack. Got it open w dremel and rotozip. Nothing lose or burnt. Planning to replace the relay. Any other ideas?

btw, this EVSE held up really well. I charged at least twice a month with it over 5 years. I bought a used one off ebay to replace it. Hopefully this will become a backup.

Got the EVSE working again!

quite the struggle removing the relay due to the large heat sinks on the board sucking up the heat. Couldn’t get the solder to melt. Had to visit one of my electronics gurus.

Had to cut off the relay’s legs and then cut down to the feet. From there we could work the solder out.

glued the case with goop and strapped the silicone cover with cable ties. Tested with both 110 and 220v.

The red wire is to ensure connection from one relay point to the circuit. There was a trace in the inside of the pc board that was not making a good connection after desoldering.
