Can anyone tell me why a 10 month old Yuasa battery would just drain out? This past thursday (june 9th), a friend and I went to a bar for some food and a drink to wait out a storm that was coming in. the rain stopped and we got riding and it started to rain again, but we decided to just ride through it. half way into our commute (about 40min), my batter light comes on, then about 5 blocks from my apartment the bike just dies...it was puttering and i was just hoping to make it home...i did not. I took the battery out and through it on a tender over night. in the morning i walked back to the bike, through the battery back in and she started up fine. the battery light was still on though, so i rode her around the neighborhood for 10 minutes, she seemed fine and the light even turned off, so off to work i went, 15 minutes later, she dies again on me. so now, i park my bike, take the battery out, jump on the subway and go to work (live in nyc). i charge the battery while at work...get back to my bike after work, throw the battery in, she starts up, i ride home and then sit out by my bike to see how long she takes to die...15min...during this time, the taillight turned off and the horn stopped working (tested it right before she died).
DOES ANYONE HAVE ANY IDEA WHY THIS WOULD HAPPEN? do i have a short? loose wires? defective battery?
