Product Description
The Roadmaster 767 is a heavy-duty manual battery disconnect for towed vehicles, intended for diesel vehicles and others with high cold-cranking amps. Many late-model vehicles must have the battery disconnected while flat towing, or the battery will drain. Once installed, you simply turn a knob to disconnect or reconnect the battery, which is much quicker and safer than removing a battery cable before every trip.
Even with the battery disconnected, some towing accessories, such as supplemental braking systems and breakaway kits, need power while the vehicle is in tow, and the 767 provides a positive current source for them. If a vehicle has two batteries on the engine starting circuit, one disconnect is needed for each; if only one battery is on the starting circuit, one disconnect is enough. The switch can also serve as a hidden kill switch to help deter theft.

Pro tipWiring and battery tips
- Protect the car’s wiring. Diodes or a separate bulb kit keep the motorhome’s lighting signal from feeding back into the towed vehicle’s electrical system.
- Watch the battery. Some vehicles drain their battery when flat towed; the owner’s manual will say whether you need a charge line or battery disconnect.
