Re: Charging gone bad, Nissan wants to replace the charger assembly

That was a temporary diode installation in the EVSE to make sure the car would charge before cutting in to the car's wiring harness and installing the diode permanently.

Another option that is a lot less expensive than letting a Nissan dealership anywhere near your car is to buy an openEVSE EVSE since it does not (per Darell) perform the diode check. If you do not have use for two L2 chargers you could sell the ChargePoint to recoup most of your cost.

Also note that Darell was able to insert a diode in the EVSE as an alternative solution. I presume he wanted to fix the OBC but if your charging is only at home or at DC fast chargers the pilot signal in the EVSE is a lot more accessible than in the car

FWIW, Ingineer posted about this issue back in viewtopic.php?f=30&t=13136&p=299259&hilit=diode#p299259. He also has some other insightful posts if you search by his handle and use the keyword diode.

Nissan thinks I'll spend $2800 to fix this. I just want this fix: https://darelldd.smugmug.com/Automotive/Electric-Vehicle/n-7QXrQ/Nissan-Leaf-charging/i-DJxC9HV but I can't find someone local to do it.

How do I find someone to do this?

Have you tried a local car audio shop? They are used to disassembling cars, and are usually skilled at soldering. Cutting a wire, soldering in a diode, and heat-shrinking it is a no-brainer.

I've contacted a few. No response.

Also, Nissan is dragging its feet on refunding me for the VCM replacement ($960~)

Any engineering university nearby should help. You have no location information in your profile area but I assume you're in the US. Craiglist or old-school hanging paper flyer on campus should do the trick.

I would print out the thread showing the diode installation, and go to a car audio shop in person, explaining to the head tech what needs done. Its such a simple fix that I can't imagine them not doing it. Just emphasize to them that there is no voltage on any of those wires on the plug, so they're not going to get electrocuted.

I should also add: Nissan absolutely refuses to discuss the diode. They want a $2800 fix or nothing.

If only location were required here on MNL. I've asked numerous times, to no avail. :/
