A method of performing a ground fault test on an aggregated battery for an electric work vehicle. The aggregated battery is not connected to the electric work vehicle, and includes a plurality of battery packs. A plurality of contactors are configured to facilitate connection to a circuit and disconnection from the circuit of each of the plurality of battery packs. A ground fault detection tool is connected to the circuit and to a battery management system service tool. If the isolation monitor detects existence of a ground fault, the plurality of contactors are opened. 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 comprises a faulty battery pack. The faulty battery pack is disconnected.
