    If it is blowing fuses probably a problem with the chicken lights.

    I agree with @BoxCarKidd. Chicken lights breed shorts to ground. Wires ran around sharp stainless steel brackets with sharp corners.

    When the lights are working, look for one thats dimmer than the others or not working at all. The short often be found near a light thats out.

    Shake the wiring and see if the fuse blows?

    Thanks, I believe I found the problem, took dash cover down, found were some wires were bare and
    arching out, taped them and tie strapped up away from the metal. Replaced more fuses, everything
    seems to be working for now. Appreciate your help.
