I know that you had a shop check the starter, but… Did they try to run the starter under load, or just “free wheel” (no load) test it? A no load test will only show if a starter runs, not if/how it will handle a load. Also, where on the starter housing did you connect the ground cable? I ask because the current
flows from the terminal on the top of the starter through the field coils and armature and grounds through the brushes in the end cap of the starter. The end cap of the starter is located on the opposite end of the starter that mounts to the engine block. To test the ground, you should attach the ground cable to the end cap of the starter, which by the way is not an easy task.

If this seems to help, check the following mating surfaces: between the end cap and the field housing (middle part of the starter), between the field housing and the drive housing (end that attaches to the block), and between the drive housing and the block. Each surface must make good contact in order for a good ground. If all are polished clean and the bushings are good, check the field coils with an ohm meter and make sure that there is not a current leak from the coils to a ground. You should have practically an infinitive amount of resistance with the starter disassembled between the terminal at the top of the starter and the field housing. If not, then you will need to replace the field coils or possibly the whole starter.

Another possibility is that the armature (center shaft with the drive gear) is dragging on the field coil mounts. With the starter apart, look for rubbing marks on the center metal part of the armature. If you see some, then the bushings need to be replaced at a bare minimum, possibly the whole starter.

I know there is a lot of info here, if you have questions, post back.
