Hello all, my first post here, but seems to be a wealth of information. I had the autopilot installed, so I'm unsure of the exact connections, so bear with me.....I believe they're hooked to the nmea 183 output on the GPS puck pigtail.
Connected to a Humminbird 858 c
AP works great 98% of the time. Problem is every 20-40 minutes it will turn hard to port without warning. This has happened at both high and low speeds , and traveling in pilot and track mode. Not a big deal except when trolling, doing something else or fighting a fish. Tangled lines!
I wrote Raymarine and they said when the AP does that its searching for direction input. I have never shown a loss of COG or GPS signal. Any ideas on this? Timing is not consistent, thought maybe the plotter was doing something on a timed basis. I've seen this problem in other topics, the "crazy Ivan". I'm just not gonna accept this as normal.
Thanks in advance for any ideas!
