Would somebody with a dead ZM like to try / test something?
I suggest we check to see if the shaft for the brushless servo has been bent or misaligned, causing it to short and/or press against the sides enough to prevent it from turning?
I'm not exactly sure how the motors for the gimbal are internally wired, but for example, the stock phantom flight motors, (I'm guessing are wired in a "Delta" configuration) if you place a multimeter (WITHOUT A BATTERY CONNECTED) on any two of the wires for the motor, it should have the same resistance as any other combination of 2 wires from the same motor. It may need to be disconnect from the ESC to get an accurate reading, the ESC electronics might cause/change the resistance shown. If two of the wire are showing continuity, or 0 resistance, then the motor has a "phase-to-phase" short, and will get hot or possibly "wobble". It will also likely burn out the ESC powering it.
If somebody could disconnect there servo from the controller board and test the wires for the servo, I may shed some light on what is going on.
