hi daytonaturbo
had a friend that had the same problem.on a jeep.
put a new starter on it,no go.
it's in the cable,the cable will corride down
inside the insulation,and you can't see it.
take a test light,and start at the top of post.
and work your way down.about every 1/2" or so.
as you work your way down and the light does not
come on.you have found the problem.a thing like that can drive ya nuts,trying to find the problem.
we put a new cable on,and it woked just fine.
