Doug is right and what he says is true ford forgot that there truck may 
last longer than the payment book. I have had ford for many years and 
found that when the first problem comes up with electrical system do as 
farmer says put on grounds. from battery to engine and from battery to 
frame. It cures many problems we don,t even know we had.But i bet it 
will cure Joes problem.
