My battery (5 years) has been on the way out for a month. The bike starts right off the tender and is good all day, but overnight, no good without the tender. I was hoping to get to the end of the year, but it was not to be, I was ready for a 37 deg. ride this morning, and got the one big klunk and tic.tic.tic as described above. This was with the tender showing a charge. I am not expecting it to be anything other than the battery.
