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.
