I went out for a ride this morning, only to find my bike wouldn't start. Completely, utterly dead. No lights, no horn, nothing turning over... zip, nadda. I managed to get a jump start, but it was pretty droopy... horn sounded like a wet fart, indicators struggled and the headlight was very weak. After 20 minutes of running, I turned the engine off, and tried to start it again without the jumpers. Again, I got nothing. Even the neutral light wouldn't switch on. To a n00b like myself, it seems like the battery isn't holding a charge and probably needs to be replaced. Or am I doing something wrong? And if I do need a new battery, where am I going to get one on a Sunday in Melbourne??
