JimLovewell: Thanks for your thorough tests and explanation of findings! I wish there were others who had done the same. Please take the time to repeat similar tests when you get your Tesla -- I feel confident that you can find a way to do all such tests safely.

If you still feel otherwise (and even if you don't), since this is a Leaf forum and most here would find it hard to adequately translate your test results made on a Tesla to their Leaf anyway: perhaps you could persuade a nearby Nissan dealership to allow you to do these same tests using their Blink and a 2013 3.3kW charger Leaf and a 2013 6.6kW charger Leaf. Any results could not help but be illuminating.

I think he's referring to the interface between the two materials/objects: the wire itself and the inside of the sleeve (pin?) that's crimped.

To me, one could cut off the ruined portion of the wire and crimp again... but then there's the other side.

You would have to have a new set of pins, and the proper crimping tool. For most of us, changing out the whole cable assembly is probably the way to go.

Yep. That's what I meant. The pin/sleeve's inner surface would still be messed up, if it's not replaced.

Does your car have a single 40 amp Tesla charger, or 80 amp "twin" chargers?

A cheap repair is just modify the Blink and replace the REMA J1772 with a Yazaki, ITT or Leviton quality cable for under $200.

End of issue.

I am getting the "twin" chargers. Getting an additional 10KW of chargering for only $1500 is quite the deal compair to the cost of DC charging equipment.

Yes, I agree. I have already order the ITT from Leviton to replace the REMA plus cable.

I cannot help to wounder what is going bad in the REMA plug. It is bad workmanship (the wire crimps) or is something wearing out on the connector sockets? Or manybe both.
