Any of you guys have any hints for troubleshooting a heading
sensor on a
Raymarine Pathfinder system? The system consists of RL80CRCplus and RL70CRCplus plotter/radar displays and the usual
GPS and other paraphernalia including
fluxgate compass and rate gyro. The
autopilot is a 6001+.
The symptoms are: Heading erratically varies wildly from reality, up to 180 degrees, then sometimes shows correct heading. The
autopilot functions flawlessly. MARPA doesn't
work.
I've checked connections, but I don't think I've found all of them
Do they just go bad? Do they sometimes require calibration? Is there are decent procedure for diagnosing them? The manual is unhelpful. Thanks in advance.
