A load driver includes a microcomputer controlling an ON-OFF switching of a first relay and a second relay. The load driver also includes a fourth switching element performing an ON-OFF drive of the first relay based on a drive signal from the microcomputer, and a fifth switching element performing an ON-OFF drive of the second relay based on a permission signal from the microcomputer. The load driver further includes a third switching element prohibiting the ON drive of the second relay by the fifth switching element to power a motor with power from an accessory battery via the first relay when the microcomputer outputs a “Lo” drive signal.
