Roadmaster 767 is a heavy-duty manual rotary 12V battery disconnect for applications that require the starting battery to be disconnected when flat towing. Its maximum manufacturer ratings are 300 amps continuous duty and 1,000 amps surge; the 1,000-amp specification is not a continuous current rating. Its higher surge rating makes it suitable for selected diesel and gasoline vehicles requiring greater cranking capacity. The knob-operated unit typically mounts under the hood, includes a mounting bracket and provides a positive auxiliary power terminal for accessories that must remain energized. Roadmaster specifies one disconnect per engine-starting battery. Confirm all vehicle and battery ratings before fitting.
