Product Description
The Roadmaster 766 is a remote battery disconnect for gas-powered towed vehicles. Many late-model vehicles must have the battery disconnected while flat towing, or the battery will drain. Instead of unbolting a battery cable before every trip, this kit uses a marine-grade solenoid so the battery can be disconnected and reconnected with the push of a switch.
Even with the battery disconnected, some towing accessories, such as supplemental braking systems and breakaway kits, need power while the vehicle is in tow. The 766 provides a positive current source for those accessories. One disconnect is needed for each battery on the engine starting circuit.
For diesel vehicles, Roadmaster specifies the heavier-duty 767 instead. Contact us with your vehicle's year, make, model and engine if you're unsure which you need.

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.
