[C320-list] ST 4000 Problems

[Robert E. Sloat]

If after calibration for deviation does not work, check out Raymarine 
support on line.  I had problems with my autopilot last year and searched in 
Raymarine's autopilot trouble shooting drop down under fluxgate compass and 
eventually found a test procedure to use. You test the resistance and 
voltages across different connections at the fluxgate compass and at the 
control head to determine if the compass or the control head is the problem. 
You need a VOM meter to do this.

I very thoroughly checked the area around the fluxgate compass and there is 
nothing that could interfere with the compass.  I went through the dealer 
setup at the slip to reset as much as possible there and will do the compass 
deviation this weekend and hope that solves the problem.  The unit has 
worked flawlessly for 5 years and is much used.  I spoke to a surveyor who 
has a Catalina 380 on the same dock and he thinks it's the deviation.

Any chance your tool box is on the sole right above where your flux gate 
compass is mounted?  If so, I've been there done that.  Worked much better 
when I moved all the metal away from the flux gate.

?
Had the shakedown sail today and while all other systems are fine, the
autopilot seems to have lost its mind.  LOL

Despite repeated setup attempts using the Raymarine setup directions, the
heading continues to be incorrect.  The heading displayed is no more than
10-15 degrees from the heading setting on the last setup.  For example, go
through the process to align the autopilot with the Ritchie compass.  Enter
a setting of 90 degrees which appears to be saved.  Change course to 270
degrees per Ritchie compass but the Raymarine still had a heading of 90
degrees.

Comments/Suggestions??

Thanks!
