So I have a 2017 rebel 300(it's my wife's) I have a idea that it might be a toasted battery but here is the issue. Bike probably hasn't been started in 5 months. It ran fine during that time. I went out today 12-17-18 and nothing... Lights and odo turns on but starter won't turn over at all. I've tried booking the battery up to my other bike and nothing and tried it with my truck. Still nothing. But everything else electrical works. Any ideas.
