A faulted circuit indicator includes: a power source; a sensor system configured to measure a voltage at the power source and a temperature at the power source; a controller coupled to the sensor system. The controller is configured to determine a health status of the power source based on the measured voltage at the power source and the measured temperature at the power source. The faulted circuit indicator also includes an indicator module coupled to the controller. The indicator is configured to provide an indication of the health status of the power source.
