We've got a Raymarine
SPX5 computer connected to a ST6002 interface controlling a wheel
pilot on our 28ft sailboat.
Recently we've been getting a low voltage error and the wheel
pilot shuts down. On our last trip out, the fuse in the line to the computer blew, not sure what that means.
I've used a voltmeter to check the voltage on the screw tops of the power wires going into the computer, and gotten a reading above 12v. But at the screw tops of the wires going out to the motor
, I'm getting a reading of about 6v, when the autopilot's motor
is drawing power. The batteries are fine.
Can anyone recommend the best way to trouble shoot this issue?
