    Blown bulbs?

    Blown main fuse?

    Check the charging system. Possible faulty regulator.

    Need directions? E-mail me, I kept my manual when I got rid of the bike (it covers yours as well).

    How is your battery, as I recall those bikes are kick start, so if the battery is dead you may not notice it. However, if your battery is dead it will not absorb the voltage spikes of the charging system which may then cause your lights to blow out. Have your battery charged and then tested, once you have a good battery I think your problem will be solved.
