1. A transcutaneous energy transfer system comprising:

  • (a) an internal component comprising a power-consuming device and an internal coil electrically connected to the power-consuming device, the internal component being adapted for mounting within the body of an animal;

    (b) an external coil adapted for mounting outside of the body;

    (c) a coupling detection circuit operative to provide an indication of whether or not the external coil is electromagnetically coupled to the internal coil; and

    (d) a drive circuit operative to apply a power-level alternating potential to the external coil responsive to an indication from the coupling detection circuit that the external coil is electromagnetically coupled to the internal coil, and to apply a test-level alternating potential less than the power-level alternating potential to the external coil when the not applying the power-level alternating potential.
