Sounds like both the motor and the Amprobe were faulty. It only read 11 amps?

If your connections were sound and to the correct terminals, the rewind must have been faulty. Was this the initial start after the service?

Where was the ammeter? You sure the rewind was with appropriate gauge cabling and enough parallel windings to carry the currents you expected and were fused for?

My guess would be they generally do a winding with multiple wires in parallel? If so perhaps one was connected and not the other 2 or 3?
