No Compass on Raymarine SPX-10

[lumphammer]

Hi all,

I'm upgrading my SPX-5 wheel pilot with a direct drive system based on a ST6002 control head, SPX-10 and Jefa linear drive. I sourced a "new - old" SPX-10 from ebay,

Yesterday was the first switch on and when i start the calibration routines I get a "NO COMP" message, where the Computer can't see a fluxgate compass.

I'm using the fluxgate compass that was working on the previous SPX-5. I have tested the resistance readings as suggested by Raymarine with satisfactory readings. I tested the resistance readings through the (disconnected) SPX-10 connector so I know the terminals were properly connecting to the conductors and not the insulation. I have tried a second fluxgate compass.

Before I take everything off to a dealers is there anything obvious I could check that I might have forgotten? Should I be able to measure any significant voltages on the connector?

Hi try looking at page 19 in the manual it mentions st6002 not st6001 as suitable autopilot controllers.

I am doing almost the same upgrade as you, adding SPX-10/EV-100 with linear drive to SPX-5 wheel drive. My plan is to use a double-throw switch to select one and isolate the other.

Are you sure the SPX-10 can use heading info from the old Raymarine fluxgate compass? I was under the impression that it had to be connected to EV-100 gyrocompass. Might be worth double checking the manual.

Some online references to the "NO COMP" message suggest it means the control head can't find the computer, usually due to power not being supplied to the computer. It may mean "no compass" too, I don't know.

I think the SPX10 has integral "gyro" correction and only needs an ordinary fluxgate.
