Default Minn Kota Ulterra Help Needed

Went out today and motor would not switch on even with batteries showing a full charge. Got home and looked everywhere for a breaker but cant find one. Unplugged the motor and plugged it back in and now the battery charge indicator doesn't even light up. Any ideas of what might have happened in exactly 1 weeks time since I used it last? It is the 112 lb model.

Bet there is a breaker somewhere. If not, it wasn't installed correctly. It should be in series between your battery banks positive(red) and your trolling motor plug.

Get a DVM and see if you have voltage going to the TM.

I currently have 2 Ulterras and haven't had a problem with either, knock on wood. But I have heard about persistent problems with control modules going bad and many have said it CAN BE related to charging the batteries with the motor connected. I always unplug/disconnect my motor when charging the batteries. On one boat, I unplug it, on my other boat, the main breaker is easily accessible so I just switch it off. Here's a thread about it Best Method/Switch to Isolate Trolling Motor While Charging?. But that may not be what caused your control module to go bad, if that is indeed what your problem is.....

Installed the new control board and that cost $360 and the motor still didn't work. Took boat and motor to shop and chased the problem to the the plug. Installed new plug for $65 and the motor worked. They claimed that irregular voltage caused the control bard to fail.
