Trouble with X30 computer

[Pcbeachbroker]

My St8001 has recently begun giving error codes "current limit" and "mot stall".
I removed the type1 liner drive and tested with seperate power source. Works in both directions. When I power the x30 on I have 13.26 v at power terminals. When I enable auto function I get 13.26v at the clutch terminals but no voltage at the drive motor terminals. With the drive disconnected results are identical but the st8001 still alarms the " current limit" or "mot stall". Any other troubleshooting recommended?

Welcome to the Raymarine Forum Pcbeachbroker,

Based upon the symptoms reported, it appears that the X30 autopilot course computer's circuitry has suffered a failure necessitating that it be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
