has anyone attempted repairing their own out of warranty EVSE?
I have just gotten a new one from the dealer PN 24276685, but I want to repair the old 24277224. Especially since GM is no longer warrantying these as a Voltec component.
I was looking at SAE J1772 and the coupler looks like this (looking at the coupler from the car side):
1-2
A-3-B
1= AC line 1 power pin (big receptacle, black wire on 24277224)
2= AC line 2 neutral pin (big receptacle, tan wire on 24277224)
A= Proximity detection pin (small receptacle, grey wire on 24277224)
3= ground pin (big receptacle, pastel green wire on 24277224)
B= Control pilot pin (small receptacle, light blue wire on 24277224)
I opened my 24277224 up and started measuring ohms and conductivity, I checked the coupler button switch and that works ~0 ohms normal, ~50 depressed
through the cable from the coupler to the box all the wires look good EXCEPT:
3 and B
It looks like I have a broken wire from the coupler to the box, could be an easy fix
jsut need to find a 4 conductor cable rated for 125V at 16-20A
