Just posting this to give people a heads up. Replaced the battery in my 2012 Level 2 back in August and really haven't needed to plug in the battery tender until recently. First time I plugged it in the amber light flashed so I left it alone and went in the house thinking it would turn green as usual. An hour later, still flashing so I now knew something was up. Bike started OK so I left it for the next day to investigate. Plugged the tender into the other bike and all was well so I next plugged my heated gear in thinking that maybe the leads weren't hooked up. (local shop did the battery r&r) Heated gear worked OK so off came the side cover, all looked well. Pulled the fuse, looked OK, checked with a multimeter to be sure, it was fine. Pulled the battery tender lead off and OHM'd it out. Negative side was fine, positive side showed open. Near as I can tell visually is that the receptacle in the SAE plug broke and the contacts may have been pushed into the housing, too far to make contact with the plug. I had a brand new spare lead so I hooked that up and all is well. Never saw this before and I'd estimate this had been plugged and unplugged several hundred times so I just wanted to share in case anyone else has well worn battery tender equipment. Cheers!
