Roadmaster Hy-Power 790 Pack of 1 Diodes Compatible with RVs & Flat Towed Vehicles | Prevents Electrical Feedback Between Towed Vehicle & Motorhome | Ensures Safe, Reliable Light Operation
Roadmaster 790 Hy-Power Diodes are compatible with RVs and flat towed vehicles.
They prevent electrical feedback between the motorhome and vehicle lighting systems.
The diodes allow power to travel only from the RV to the towed vehicle’s lights.
They protect both systems from reverse current flow during operation or when parked.
Built with a heavy-duty aluminum heat sink, they efficiently dissipate heat.
Designed for continuous 85-amp operation, they ensure consistent long-term performance.
The diodes and components are sealed in epoxy and enclosed in an aluminum housing.
This design protects against moisture, dirt, and corrosion for lasting durability.
