    You did go to Basscliff's and get a wiring diagram - the 650's should be similar - how many fuses do you have? no on/off for headlight?

      2 fuse boxes 1-1, 1-4 fuses. no headlight on/off switch. makes me wonder w/ the condition of the roads, cause of the winter, something could off come loose?

        Copy a color version of 82 gs650 from that link and start chasing wires around.Yes, could be Christie's roadwork or mice vacationing in your harness. Is this bike new-to-you?
