[CA] [CA11] EV1 reversed course

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Dirk,

In all of my years of supporting autopilot systems, I have never heard of a system yielding such a high deviation after performing the steps required to calibrate / detect magnetics (i.e. determine the deviation table for the deviation sensed by the heading sensor). While an autopilot's ability to operate in Auto mode would not be expected to be impacted by an autopilot producing an incorrect heading value, it would be expected that the autopilot would report an issue when one attempts to operate it in Track mode. Please click here to view a FAQ addressing items to check in the area of the EV-1 CCU. Please additionally check the fasteners used to install the EV-1 CCU's mount with a magnet to ensure that the fasteners do not feature ferrous content. Should the problem persist and you have verified that the EV-1 CCU's orientation arrow is point toward the bow of the vessel, then it would be recommended that the EV-1 CCU be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
