A method of performing a ground fault test on a plurality of battery packs of an aggregated battery of an electric work vehicle. A circuit is configured to connect the aggregated battery to an isolation monitor. A plurality of contactors are configured to facilitate connection to the circuit and disconnection from the circuit of each of the plurality of battery packs. If the isolation monitor detects existence of a ground fault, the user of the electric work vehicle is notified of the existence of the ground fault. The plurality of contactors are opened. The closure of the plurality of contactors is sequenced to include each of the plurality of battery packs in the circuit with the isolation monitor in turn. The isolation monitor is used to determine whether the battery pack that is included in the circuit is a faulty battery pack. The faulty battery pack is disconnected.
