A controller of a vehicle power system closes a pre-charge contactor and one of a pair of main contactors to electrically connect a battery and inverter such that current flows through a pre-charge resistor. The controller also opens the pair to electrically disconnect the battery and inverter, and closes a switch configured to complete a circuit such that charge acquired by a capacitor of the inverter is dissipated via the pre-charge resistor.
