Help PLEASE! My 2011 Leaf charges ok with the OEM 110v and dealer’s 220 quick
charger. Joined the Enel X program and was sent a Juice Box Pro 40. Upon plugging into the charge port (right, small one) I get one beep, no blue dash lights, Enel X sends me a replacement, same result. Dealer does diagnostics ($150) says everything is fine, another replacement Juice Box, same result, back to dealership for evaluation, everything ok, new model JB with same result. Folks 4 Juice Box units cannot be all defective. Frustrated after 4 units, 2 dealer visits and no solution. Any thoughts? Thanks in advance.
