    If you can blow one horn and not two I would say you have corrosion on a
    connection limiting the current flow to the dash. Watch the positive
    voltage at the dash while you blow the horn. I bet it is dropping to 6 or 7
    volts. You can do this same voltage test with a load at different locations
    working toward the battery. You might just find a caroded inline fuse
    holder or something like that. Good luck Neal
