After getting another batch of 4 chargers (luckily for next to nothing) that didn't work, we realized that the chargers were from a scrapped Tesla Supercharger, 1014963-05-B. It appears that Tesla scrapped a bunch of V2 Superchargers last year and that a number found their way onto the market. Notice the description after the part number
After looking back at our past list of chargers, I realize that our last 2 Ebay purchases were also from Superchargers ,(but were being sold as out of actual Model S vehicles). There are still some being sold on Ebay. I have contacted the individuals and asked them to remove, or revise their ads. I quickly went through the support forum and see that some others that were having problems also had these same units.
Bryson provided some info on part numbers in the past that says that all -05- units won't work:
I have combed through the forum posts and see evidence of Rev J,K,G,L chargers working. All Gen3 chargers also appear to work (which would be the equivalent of a later Rev).
So, my guess is that early Gen2 chargers do not work. The change over was probably somewhere in the Rev E release. If anybody is buying a charger, at this time I would stick to Rev F or later. It would be helpful if others could post the REV of their unit and whether it worked or not.
