Joe I read this after my "alternative" reply.  If you have
that much chassis rust you'd probably be better off to
run an insulated ground cable like the others have suggested
and after you make the connections seal the ends with heat
shrink tube or something.

I'm sure it doesn't help that my truck is almost 18 years old, and I live in 
a winter climate that uses lots of salt.  The underside of the truck is 
pretty rusty.  I had hoped it would last forever, but after crawling around 
underneath it this past weekend, I'm having my doubts.  I'm convinced that 
it will fail structurally before mechanically.  It's a 1997 F250 with 
320,000 miles on it.

Enjoy, Joe

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.
