took the boat out tonight, had some issues with my electric trolling motor.
It is a minn kota bow mount 80 lb thrust, Power Drive, Autopilot (has the transducer built in). About 3-4 years old, will have to go back and check out the exact date of purchase.
The first part of the trip, it was doing fine (as it's always done), but after a while it started doing some wierd things. When I pressed the foot pedal to turn left (only slightly), it would do an almost 180* turn (as in, I would only tap it to turn slightly, but when I removed my foot it continued to turn a certain distance). I didn't want major changes in direction, just slight adjustments. It wouldn't make small adjustments though, only big adjustments. So I would try and go back slightly the other direction, same deal..... it would turn way past the point I wanted to (no, the pedal was not stuck or anything..... I looked for anything that may be interfering with the foot pedal). The 'adjustments' the trolling motor was making were always the same distance from left to right.
So then I thought I'd try autopilot.....same deal - it wound up making non-stop adjustments (to the same degree), back and forth, back and forth, back and forth....... so I'm thinking there's something definitely wrong with the computer in this thing. So I turn it off. Amazingly - while in the off position - it continued to swing back and forth! so I unplugged it, really confused at this point.
Let it rest for a while and tried it again.... initially, it worked fine, but after a few minutes it started to randomly turn on it's own.
At home, I set it up, plugged it in, played with it for about 10-15 minutes and suprisingly - not one single problem. On, off, no problem. left right, it turned only as far as I wanted it to. I let it run for a while and it behaved normally. This is really strange.... I would think if there was a problem on the water, it would still have that problem a few hours later at home.
anybody have a similar problem or any suggestions? In the end, I'm sure I'll have to take it to a Minn Kota Authorized Repair Center and since it's about 3 years old, I'm sure it's out of warranty.
But I'd sure like to know what this may be.
