Riding home from work my 93 F2 lost all power. Fuse was blown in the relay next to the battery box. Battery was about 5 years old so went ahead and replaced. Did initial charge after buying a new battery before installing in bike. After fully charge and installed, bike ran for about 5 minutes and then cut out again. Tried to restart but no power and battery is drained. Is there any other part of the electrical system that I need to be checking out??
