This is Ultrex #2 for me, as I had one of the first ones and it died while on a fishing trip. Minn Kota replaced it, and this is the second one. I was just on Lake Okeechobee this last week, when it seemed to do just as the first, dead in the water. No power, I was not able to move the motor left/right or spin the prop....nothing. I motored back to the ramp, took it to Roland Martins place in Clewiston, and when I got there, it worked fine. He checked the batteries, 3 Interstate installed about 1.5 years ago. When he first tested each battery, battery number 2 read 11.6 volts, and the other two read 13.3 volts. then he tested the second one again, and it read 13.3 volts like the other two. He thought possible battery issues with the #2 battery.
Next day I'm on the water, trolling motor is working fine and I charged the batteries that night to full capacity. I was rounding a point when it just when blank again. I go back and check the breaker, check my Blue Seas exterior switch I've installed since before the Ultrex, all good. I sit down in the seat to ponder the situation, no movement on the boat and I'm not near anything, and I hear the 3-4 quick little beeps it makes when I first turn it on. Now It has power! I motor 35 yards, then it dies again. 10 seconds later, it beeps and is back to life. All connections are good, I got under the bow panel and checked the connections there, and checked all the connections in the battery well.
It seems to be possessed, as it comes on at completely random times. I'm not sure what the problem is. Going to call Minn Kota tomorrow, and run it to my dealer to see if they can diagnose the issue. Any thoughts?
