I have a partially working. 48 amp onboard charger for Model S. Pulls 6k from wall HPWC. S power reduced. Replaced for $2700 with a new one that Tesla upped to 72 amp via software as a pat on the back. Apparently there is one partially working module inside. Other one would have to be fixed. Big box has not been opened. $1000 or best offer plus actual shipping costs. No one really came back to me with an estimate of value so I took a stab in the dark.
