Keith,
Yes,? to both of your questions.?
A short on the windings or an open on one of the primary windings could cause your symptoms.?
You use the terminal program for the diagnostics, including the sweeps.? Please read the operations manual on setting up and using the terminal program.? To avoid an extra turnaround, what OS do you have on your PC?? The OS will change how we describe answers to your questions if you encounter issues getting the terminal program to work.? I am most familiar with Windows, but I could provide some help with Linux.? I do not have access to Apple iOS devices.? You will need support from others in the group to use iOS.
