Thanks gentlemen,
I can confirm i have changed the sensitivity settings and am not locked on track. It turns down
wind not up wind. i will check the gain question. My suspicion is the
batteries might be on the blink and will check next time on board, after xmas.
The system was fitted 12 months ago.
Thinking back to the first time this problem happened, it was early this year while sailing from Wilson's Prom to Deal Is Bass Strait (Australia), the
motor was off but the
batteries were in slightly better condition than now. We sailed for 8 days with the problem only arising intermittently. But that may have been because there was a lot of
motor sailing involved.
Thanks for your help. I will report back after checking batteries and gain and all
electrical connections. (I forgot to mention, the AP is connected to the hydraulic stg system)
