1. A cochlear implant system comprising:
a cochlear electrode;
a stimulator in electrical communication with the cochlear electrode;
a signal processor in communication with the stimulator;
an input source in communication with the signal processor;
an implantable battery and/or communication module, the implantable battery and/or communication module being configured to provide electrical power to the signal processor; and
a plurality of conductors electrically coupling the signal processor and the implantable battery and/or communication module; wherein
the signal processor and/or the implantable battery and/or communication module is configured to:
ground a first conductor of the plurality of conductors;
apply a plurality of test signals to a second conductor of the plurality of conductors while the first conductor is grounded, each of the plurality of test signals having a different frequency; and
measure one or more electrical parameters of the first conductor, the second conductor, and/or between the first conductor and the second conductor using the applied test signals.
