Ev-1 not seeing drive

[Chuck - Raymarine - Moderator]

Ralph,

It is recommended that the motor and clutch leads be disconnected from the ACU, that the fuse be replaced, and that the autopilot then be powered ON again. Should the fuse blow when operated without the drive leads connected, then the problem would be fault isolated to the ACU. However, should the fuse not blow when operated without the drive leads connected, then there would appear to be a problem with the drive unit or cable connections to the drive unit. The faulty component should be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
