    Should be a ground wire coming from the headlights and turn signal that is attached to the frame. Check and clean the ground wire.

    I found a similar issue once where a wire had worn through and would blow fuses pretty regular. It was under the steering wheel at the 1st steering knuckle inside the plastic cowling at your knee's when driving.
