Hi all,I was hoping someone could save me a trip to dealer.i had leaf plugged into evse ,not charging but waiting for timer,I had to cut power at the breaker to do other elec work.Evse reset ok but car does not respond with ohm load on pilot .Evse doesnt even know its plugged in...is there some kind of reset on built in leaf charger?thanks in advance...kpc

Unplug the EVSE from the car and then try turning the car on and back off. I had a similar thing happen to me once and that cleared it. I assume you have already tried rebooting the EVSE...

Are there any error indications on the dash? It would probably be worth resetting the car by disconnecting the 12v battery to see if you can clear any error state.

If the LEAF's Control Pilot circuit's diode blew (opened), the EVSE would not recognize that it was connected to a car, and thus no charging.

Probably needs a dealer, since the diode is (apparently) in the Charger (behind the LEAF's back seat).

Best to have expensive things powered Off, AND disconnected, when the power goes off, and ESPECIALLY when the power comes back ON.

Testing for the diode should take about 2 minutes with a $5 VOM, I think.

after dealer got advisor II computer fixed,rebooting car (12 volt battery disconnect)checking grds and assorted fuses and finding nothing wrong,ended up replacing entire charger unit.Car is now charging normally,but I have no idea of what failed in charger...kpc
