I sent a support ticket in too.
However, if anyone has ideas, please let me know.
J1772 was plugged into car and I got GFI errors. Then unplugged it from car and then got diode check errors and vent required message. Tried disabling those checks and then noticed sparking on the wires entering my J1772 plug. The cable had got damaged due to ice/snow/rain and lack of an adequately long enough strain relief. Flipped the breaker and removed the OpenEVSE and repaired the burnt wires/cables (soldered them at work and covered with heat-shrink tubing and electrical tape). Plugged OpenEVSE back in and it booted fine but then I restored the diode error and vent check options and now I'm getting those errors again, without plugging into the car. I opened up the OpenEVSE and don't see any damage inside.
We would recommend checking the DC/DC power supply and the pilot OPAmp circuits for damage. The DC/DC should be outputting -12v and +12v DC.
ok, I'll check those voltages out Chris.
