Roadmaster RM-766 Automatic Remote Battery Disconnect Kit with Solenoid

Eliminate the inconvenience, grease, and hazard of repeatedly unbolting battery cables before flat towing with the authentic Roadmaster RM-766 Automatic Remote Battery Disconnect Kit. Specifically engineered for dinghy-towed vehicles requiring battery disconnect during transport, this heavy-duty solenoid system enables you to isolate your vehicle's starting battery at the push of an in-cab switch without opening the hood.

Many modern late-model vehicles require the battery to be disconnected to prevent severe parasitic draw while towing behind a motorhome. Unbolting cables every trip damages terminal posts and wastes valuable travel time. The Roadmaster 766 completely automates battery isolation while maintaining a dedicated continuous positive current source for supplemental braking systems (such as the Roadmaster InvisiBrake or Even Brake) and breakaway safety circuits.

Key Features & Engineering Highlights:

• Instant In-Cab Remote Activation: Pre-wired push-button switch mounts cleanly inside the vehicle cockpit—disconnect your battery in seconds without popping the hood.
• Dedicated Accessory Power Tap: Provides a continuous 12V positive current source to power supplemental braking systems, breakaway switches, and emergency monitoring circuits even while the main vehicle electrical system is safely isolated.
• Continuous Duty Automotive Solenoid: Rated at 200 amps continuous duty with high-current 600 amp surge capability, built to endure harsh underhood heat cycles and vibrations.
• Anti-Theft Deterrent Capability: Can alternatively be wired as a discreet, hidden master kill switch to protect parked vehicles against unauthorized starting and theft.
• Comprehensive Turnkey Installation: Complete pre-assembled kit including industrial solenoid, in-cab switch, heavy-gauge copper wiring, mounting hardware, and step-by-step instructions.
• Professional In-Store Installation: Expert installation and dinghy setup available at Truck Guy Upfitters (510 W North 1st St, Seneca, SC 29678).
