An electrical system includes a high-voltage bus connected to a rechargeable energy storage system (RESS) and a high-voltage component connected to the RESS via the voltage bus. The component defines a service opening spanned by a removable cover. The electrical system may include a fastener connecting the cover to the component, as well as a battery disconnect unit (BDU) having a high-voltage switch device connecting the RESS to the high-voltage bus. The switch device closes responsive to a low-voltage drive current to connect the RESS to the high-voltage bus. A drive circuit conducts the current to the switch device. An electrical connector has multiple connector pieces collectively forming a switch in the drive circuit. Disconnection of the pieces from each other opens the switch to interrupt the drive current and cause the high-voltage switch device to open, which disconnects the RESS from the high-voltage bus.
