Was out riding in the huron mountains all day . Stopped at mt shasta for dinner . came out started sled i had dim h/lamps . jiggled wires h/lamps came on and to camp i went . Next morning started sled had dim h/lamp jiggled wires and h/lamp came on . my question is jiggling the wires is coincidence for h/lamp going on . should i buy a voltage regulator because its not if they go bad but when . anyone have a bad wire somewhere or symtoms of regulator going south . Thanks , i finally remembered my password lol
