Simrad AP12H

[Huntfrisco]

Any of you guys that have Simrad auto pilots have had trouble cailbrating your compass. I can't seem to complete the circle & 1/4 minimum turn for the double beep. I get about a half turn in and the green starboard light flashes. Ive tried speeding the turn to increasing the turn.....no luck with either

If you can remove your regular boat compass, put it down near where you have the fluxgate compass mounted to see if there is some magnetic interference in that location that is preventing the compass from calibrating.

When I installed my AP14, the horizontal bulkhead I had planned on mounting the compass on had my boat compass spinning (too close to the aluminum gas tank or something, I don't know what), but I moved the fluxgate compass to a vertical bulkhead where the boat compass didn't go screwy and it calibrated fine.

That would be my first step in diagnosing the problem.

OOPS just read where you saind AP12H, mine was an AP14R, not sure what is different on the hydraulic units from the mechanically steered units, but if you still use the fluxgate compass, that would be my first stop.

Never did get my AP12H to calibrate either. Don't know why but it works just fine without the calibration. I was going to call tech support at Simrad before I pull the boat and address the problem after the Salmon are in the river. What Tim said was on the lines of what I was thinking also. Be sure to let us know if you find the problem.

I moved it to the exact center of the boat, the gas tank is polymer so metal should not a problem..will let you guys know..thanks for the input
