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.
Schematics are located here.
Did you figure it out?
I'm facing to the same error trying to charge my Renault Kangoo
Thank's for your answer Roger.
I just receive a new box and test it with my Kangoo.
I hop that it's not a fail of the controller.
By the way, what do you call controller, the display or the board where is plugged the coils ?
I found my problem !!!
I was the delivered cable with plug type 1
The pilot and proximity were reversed. I had to cut the cable and dismount the plug to reverse the pin.
Bad quality of product from open-EVSE
Fortunately no damage to the car nether the charger.
For information the pilot (pink cable) should be on the left looking to the plug with ground on top for plug type 1.
Yes I did open a ticket but the answer did give me a solution, ground and pilot were well connected:
Both Diode Check and Vent Required have to do with the Control Pilot. Ensure you have the correct wire connected to the control pilot and the controller is properly grounded.
We are sorry to hear there was a problem with our product, the J1772 Type 1 cable. During trouble shooting we have to explore possibilities starting with the most common. We do not always get it right on the first pass.
We have notified our supplier and have inspected all units on hand. All units in stock have tested good. It appears the assembly error was an isolated issue.
