Brought to the attention of Raymarine
, Raymarine kindly and diligently replaced the course computer card, a stern mounted fluxgate compass
instead of the previous mast
mounted was connected to the pilot and another five days test in the same previous weather
condition produced no losses of heading but stable piloting by adjusting the Response as necessary. Even so that the mast compass fluxgate
tested within the specification, I suspect that its reliability
may be affected by is placement to fare away from the pitch
and roll centre of the boat.
Procedural check from Raymarine
In standby, Look at the Compass data on the controller, manually steer the boat in a slow Clockwise circle. Watch the compass readings. Does the figures increase/decrease evenly without jumping?
After that, take off the compass and check with a Multimeter:
The Multimeter should show:
Wires ---- Resistance
to Blue ---- 6 to 12ohms
Red to Green ---- 3 to 6ohms
Yellow to Red ---- 3 to 6ohms
Yellow to Green ---- 6 to 12ohms
If it does not display this then the Fluxgate is faulty and needs to be replaced.
If the compass does not jump and you get readings that fall within the above guidelines then the Fluxgate is fine, if it fails any of the tests then I would recommend that you replace it.
