If the starter power was left on, would the load on the compressor nut not be removed as soon as the engine started spinning faster than the starter motor? I wouldn't have thought that the engine would drive the starter motor to that sort of extreme speed.
This is not a criticism of the diagnosis. Just interested in exactly how the bendix would behave.
from what Phill told me the starter motor was fried, the comutators looked as if they had gone way over speed.
these turbines do have quite a lot of torque, certainly enough to drive an electric motor to destruction.
