Hi Richard,
Have you checked all the connections between the battery and ground and B+
and the starter? If both batteries are unable to provide the current the
starter needs there may be a high resistance somewhere in the circuit. If you
access the cables you could run a jumper cable in parallel and see if that
helps. If you run it as a redundant ground from B- to the engine ground and it
starts, there's likely high resistance in the ground circuit.
This back-yard diagnostic method is only slightly removed from the
beat-on-the-starter-with-a-hammer diagnostic technique, but it might turn up
something.
