Looking for a suggestion how to proceed. Here's the background info. 2013 S with 14K miles and 850 charge cycles on the bike. I bought it used, so I don't know if the charger is original or not. I have put the vast majority of the miles on, commuting each day in nearly rain free Los Angeles, CA. Two days ago I noticed the power cord was badly burned on the female end, that attaches to the bike. I cleaned up the contacts on the bike, which appeared to be OK, and the next day I used a brand new cord. When I pulled the cord out after charging, one of the pins came out of the bike (!) and was stuck in the female end of the cord! There was evidence of some heat again on the plug. Clearly I still have a problem. Leading up to this, I recently seemed to notice more of an audible sound when I plugged the cord in (I was always using the outlet side first, then the bike plug). With the new cord, I reversed the order after having read some suggestions to do so (although, when I had asked a Zero rep, they said it didn't make a difference). But, because it would be easier and less expensive to replace the 110v outlet, then the internal cord on the bike, that was the direction I went in. Anyway, even today, the bike did still charge completely and in the normal amount of time. Is the charger on it's way out? Should I first attempt to obtain and replace the internal cord on the bike? Should I replace with a new charger from Zero? Or do you have a suggestion for another, currently available brand? I could manage with a non, on-board charger if that is the most cost effective repair, if replacement is necessary. I will add, my pack temperatures have not been abnormally high, the most recent download show that it has never exceeded 45 degrees (C), while either riding or charging. Thanks all! I appreciate your input! Marc
