so my buddy has the above bike, and the other day while we were riding his headlight went out so we pulled his fuze box and easy blown fuse so we put the spare in and it fixed it we rode two blocks and it blew it again...so we went through and checked all his headlight connections and with out pulling to much plastic we seated everything nice and snug....went to cycle gear bought 2 more fuzes...seemed fixed went two more blocks and it blew again...when we wiggled one of the headlights went off and on the first time....do you think were just missing a connection somewhere and the bad connection is just popping fuzes or is there a more serious problem?
