st5000 plus

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum pirahna3,

Based upon the symptoms and troubleshooting performed, it appears that the ST5000 (combines the functions of an autopilot control head and course computer within a single device) has suffered a failure of its circuitry. Unfortunately, Raymarine can no longer provide parts and service for the ST4000/ST4000+ and ST5000/ST5000+ autopilots. Accordingly, it would be necessary to replace the ST5000. Should the the ST5000 currently be interfaced to a Type 1 Hydraulic Pump, then it would be recommended that the ST5000 be replaced with a T70156 Evolution EV-200 Power (includes p70RS Autopilot Control Head, EV-1 Sensor Core, ACU-200 Actuator Control Unit, and SeaTalkng networking components to interface these autopilot components to one another). The current installed rudder reference transducer and Type 1 Hydraulic Pump may be retained for use with the new autopilot components.
