I have a 2018 Chief Darkhorse that I kept connected to a tender in my garage over the winter. I discovered a dead battery yesterday. The factory installed tender and cable are not working. Luckily, I installed another one and placed under the tank bib. The tender charged the battery and it seems to be holding a charge. But my key fob is not recognized by the bike. I changed the battery but its still not workin. Any idea on what is going on?
