i took my bike out for a ride today and as i was out the battery light came on and the check engine light followed it, it said system voltage low, i have had the bike for a few months now and it has 4k on it, i am confused because the voltage dropped to 11.7 and did not go any lower then that, but then it would jump up to normal operating voltage between 12.5 -12.8, but would not stay there and then drop again, could this be caused by a bad ground or is the alternator not charging? or could it be something else. it is still under warranty but if it is something as simple as a bad ground i would like to just fix it myself instead of taking it to the dealer because the dealer will have it for weeks and i dont want to miss out on any riding if i dont have to -- if someone could help me out i would really appreciate it--[confused]
