Minn Kota auto-pilot problem fixed

5 posts in this topic

I thought I'd post this since it was pretty useful information to know.

I have a new (in 2002) Minn Kota trolling motor with auto-pilot. Ever since I got it I have had problems where it would start spinning out of control while running - sometimes wrapping the cord around itself.

I emailed Minn Kota and they told me to have it serviced because the compass needed re-calibration.

When I took it in the service tech said it had a bad circuit board. It wouldn't calibrate correctly so replaced that piece and now its fine.

That's when he told me the interesting stuff.

Apparently, he said that auto-pilot will only work correctly if the boat stays with 10 degrees of level - so obviously even medium sized waves will upset the auto-pilot.

He also said that the compasses can have problems if they go through a lot of vibration or are exposed to water/moisture, but the water/moisture problem usually didn't happen since that part of the unit is sealed.

However, he did say that if you are rough with your trolling motor and just drop it into the water instead of being gently, and slam it back up again too, it can over time cause the auto-pilot to need re-calibration. Apparently some guys have to get this done every year.

Just what I learned today...

Thanks for the info.
My 1997 auto pilot just started doing that last fall. I thought that I was going to have to replace it. it only does it when facing north or south, no other direction.

My new one went a whole 8 hours before it needed to be serviced. I get it back tommorow, no parts needed to be replaced just an overvoltage condition on something. Anyways, didnt cost me a penny with the two year warranty. I know guys that pound the snot out of theirs and theyre still going strong..I hope mise serves me as well. Cause I am NOT easy on things. lolol Good fishin!!... Paul

yeah, I also found out the hard way, that you must unplug before charging. I fried my circuit board. FYI they are pretty easy to change out.

For the record, the reason I posted this was so other people do not go through what I did! smile.gif

I hope that everyone who posts a problem and fixes it posts the solution for everyone else. It will hopefully save at least one other person time and $$$!

    • Switched up my pick at the last second in bucket A and put Wheeler in there. Great ledge fisherman and sounds like this dude puts in more time on the water then any other angler out there.   A. Wheeler B. Evers C. Tharp D. Herren E. Omori   Sounds like the bite has been super tough. Will be interesting to see how it goes. 
    • They are drumming like crazy now. In fact, I even hear them at night. My wife said when she was a teenager growing up in rural Wisconsin, she always thought that drumming sound was the nearby powerstation.    
    • Lilac blooms are here, just haven't opened. Hearing some reports of good finds in the Houston and Lewiston areas of MN. I checked some new public areas today on the MN side. Could be decent later but too cold and wet right now. Will check some early season spots tomorrow but won't hope for much with the cold weather.
    • Nice!  Must have seemed forever waiting.
    • 6 months later and he is home
    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
