Ok so i was riding home lastnight from werk and my bike and as i was making a turn the bike just up and died. so i tryed starting it and there was nothing the battery was dead.

Two days later It happened again i get off my bike for all of 5 mins from 20 min ride and shw wouls not start again, almost completely dead battery, not enough jucice to turn over and start.

I'm thinking the alternator but i wanted to get some thoughts on the matter
