I own a 2000 FLSTC with 7300 miles. Rode about 140 miles with several stops along the way. As I was riding I noticed my speedometer stopped working, moments later the red engine light came on and I immediatly pulled over and shut off the bike. a moment later when I tried to start the bike the battery was dead, no lights not even the horn worked. I switched batteries with another rider and pulled the light fuse so as to not drain the battery sooner than what my have occured. I was able to ride another 75 miles to home. When I got home the battery still held a charge and the bike started however I did not ride it. Put a battery charger on the battery and the battery appears to be charged. Also the person that I switched batteries has had no problems with the battery from my bike. It appears the battery was charged while the bike was being ridden. So what could be wrong with my bike. Thanks!
