Method for operating a fail operational power system for a vehicle includes monitoring voltages on first and second power distribution paths arranged in parallel. Each path includes a respective first or second isolator switch effective when operative in a closed state to power the respective path by a respective energy storage device for supplying electrical power to one or more loads partitioned on each of the paths. A third isolator switch controllably operative between open and closed states is monitored. The closed state of the third isolator switch connects the paths and the open state opens the connection between the paths. When a predetermined operating mode requiring fail operational power is enabled, the third isolator switch is controlled to the open state when at least one of the monitored voltages violates a reference voltage and is controlled to the closed state when neither one of the monitored voltages violate the reference voltage.
