Bill,
It sure sounds like it's still not getting enough juice. When you tried
freshly charged battery and jumping with your truck - did you try grounding
the starter housing directly to the battery? If the ground path is weak it
would produce those same symptoms.

You can also try by-passing the starter solenoid by applying current to the
big wire attached to the solenoid that disappears into the housing - that
will rule out a bad solenoid.

It's always fun working on the starter - that just happens to be within
inches of that big slice-O-matic attached to re-drive :)
