Abstract
An engine-powered vehicle includes an engine, a battery corresponding to a battery voltage, a starter, an alternator, a plurality of switchable electrical loads, a key switch configured to control the switchable electrical loads and corresponding to a key voltage, and an electrical system health monitor (ESHM) controller. The ESHM controller is configured to monitor a plurality of voltages, to determine an operating state based on the plurality of voltages, and to determine whether an operating state is a valid operating state or a fault state. The ESHM controller is configured to set a fault alert for vehicle maintenance when the operating state is a fault state and, when the operating state is a valid operating state, to monitor a predetermined set of input parameters corresponding to the operating state, to detect certain anomalies based voltage waveforms of the plurality of voltages, and to perform a corrective action based on the anomalies.
