Rode fine all day, then it died completely no power anywhere

[ajmiller]

I had been riding around town just cruising around since it was gonna rain the next four days and when I got back home left it running while I jumped off and opened the garage door, jumped back on kicked it into first and started pulling into the garage and it died (it felt like I killed it) but it acted like I was in second or a higher gear going from a stopped position and it died. So I went to re-start it and it started to turn over BUT THEN it made a loud POP towards the front of the motor and I had no lights, horn, no nothing. It was pretty cold out and so I just said F it and pushed it into the garage and left it for the night since it was gonna rain the next day (today) and work on it then. Well I dont even know where to start so I am asking for help before I mess anything up. Most of you seem to know a thing or two about gems so let me know what to do and what to check PLEASE!!!

Thanks everyone!
