1. A communication device comprising: an electrical component; a sensor coupled to the electrical component and configured to sense an electrical characteristic of the electrical component; and an electronic processor connected to the sensor and configured to: receive, from the sensor, a series of measurements corresponding to the electrical characteristic; determine, from the series of measurements, a first electrical characteristic profile; compare the first electrical characteristic profile to a predetermined electrical characteristic profile to generate a comparison; generate an indication of a possible component fault based on the comparison; and compare the first electrical characteristic profile to a plurality of predetermined electrical characteristic profiles to determine a location of the possible component fault.
