    headlights draining battery

    Getting 13v on idle cold start and +/-9v with headlights on. Can anyone tell me what's wrong with this or what you done to fix it.

    The most common problem is poor grounding. Try running an extra ground wire from the battery to the frame and the motor making sure all connections are good. Also put dielectric grease on all the plugin connectors

    If the ground does not fix it, it is probably the rectifier/voltage regulator.
