Has anyone had issues with Challenger battery or charging system? My bike sat in the garage for 12 days (since I had minor surgery procedure) and battery was completely dead when I wanted to ride today. Put a 30 amp quick charger on it for 5 minutes and the solenoid would just click, eventually it started and I was able ride. Gauge read 14 V. Just wondering if anyone else had battery draw issue when sitting for such a short period? Thanks!
