Overview

The Garmin 010-11533-10 is a solenoid power cable used in GHP Reactor Mechanical/Solenoid/Retrofit autopilot installations where the autopilot ECU controls hydraulic solenoid coils.

It includes protection diodes and self-healing fuses in the cable to help keep coil-generated voltage spikes from reaching the ECU. This is the solenoid cable specified for Reactor 40 Mechanical/Solenoid/Retrofit Core Pack setups that steer by commanding a constant-running hydraulic pump through solenoid valves.

Key features

• Built-in protection diodes and self-healing fuses for solenoid-coil suppression and circuit protection
• Specified for GHP Reactor Mechanical/Solenoid/Retrofit systems, including Reactor 40 solenoid installations
• Intended for wiring between the Reactor ECU and hydraulic solenoid coil circuits in solenoid steering configurations
• Helps keep solenoid wiring straightforward by integrating the protection components into the harness

Compatibility and fit

This cable is used when a Garmin GHP Reactor Mechanical/Solenoid/Retrofit autopilot is driving a solenoid-controlled hydraulic steering system. It is typically part of installations where a third-party solenoid valve block handles port and starboard flow while the pump runs continuously.

Before ordering, confirm your autopilot core pack is the Mechanical/Solenoid/Retrofit type and that your steering system is the solenoid configuration. Verify your solenoid coil wiring matches the system voltage and the autopilot wiring diagram for your ECU.

Installation and setup

Route the cable from the autopilot ECU to the solenoid manifold or valve block, keeping it protected from chafe, heat, and moving gear. Support the run with clamps, leave a small service loop at each end, and keep splices out of the bilge where possible.

After wiring, test steering direction at the dock and confirm the autopilot can energize each solenoid cleanly. If you are troubleshooting an intermittent steering response, inspect the cable path for pinched sections, corrosion at terminals, and loose connections.

Use cases on board

This cable is a good match for boats that use a constant-running hydraulic pump with solenoid valves for steering control, including many larger powerboats, trawlers, and sailboats with hydraulic systems. It is also commonly used when retrofitting an existing solenoid steering setup to a Garmin Reactor 40 Mechanical/Solenoid/Retrofit core pack.
