smilemaker Posted August 4, 2018 Report Share Posted August 4, 2018 On the old Minn Kota trolling motor it was absolutely necessary to disconnect the motor by plug or circuit breaker before hooking onboard charger. I was hoping MK had addressed this in the new post 2017 motors. Has anyone else fried a motherboard due to forgetting to disconnect the tm . Over the years I have fried 2 24 volt motherboards and believe a fishing buddy may have fried his post 17 board. Link to comment Share on other sites More sharing options...
Bamaskeet Posted August 4, 2018 Report Share Posted August 4, 2018 I have two I Pilots and one Ulterra, and never disconnect the power while charging my batteries. Link to comment Share on other sites More sharing options...

X2, read my manual and it doesn’t mention that. Ipilot is 2008 vintage. Link to comment Share on other sites More sharing options...
smilemaker Posted August 6, 2018 Author Report Share Posted August 6, 2018 The manual for my Minn kota 2017 says to unplug before charging the batteries. I have had 2 of the boards go bad while charging with the tm pluged in on the old 24 volt motors. My fishing partner had his 2017 36volt go out and it is only a year old The problem with boards is well discussed on the web Link to comment Share on other sites More sharing options...

bernieNC Posted August 6, 2018 Report Share Posted August 6, 2018 I always flip the breaker between the batteries and the TM after use. Why not it makes to much sense. The breaker needs to be in a convenient location. Link to comment Share on other sites More sharing options...

The breaker needs to be in a convenient location. Me 2. Every time! No reason not too! Plus, you don't have to unplug by using the breaker!

rubble Posted August 6, 2018 Report Share Posted August 6, 2018 I moved my breaker switch to just above the battery switch on the CC so when I switch battery to Off I flip the breaker as well. Plus when I’m not in the water, my TM is unplugged. Having a Battery Tender plug makes it so simple. Link to comment Share on other sites More sharing options...
smilemaker Posted August 6, 2018 Author Report Share Posted August 6, 2018 It seems that Minn kota is aware of the situation. It seems that there should be an answer to protect the board. You can find about anything on the web as some people say that stray static electricity can dry the board. How can something withstand abuse on the water be so vulnerable.

Wanaflatsfish Posted August 9, 2018 Report Share Posted August 9, 2018 As well, there is discussions on the Ulterra as well, you should unplug when not in use as the draw on the batteries...small amount of voltage, but, enough if you were to not use for many weeks, it could draw down the batteries....I always unplug as well since I have the Battery Tender plug...it takes 20 seconds and I usually spray some corrosion protection in the plug on the male and female sides....three years and not an issue...same DEKAS's 27 series...but, I do charge right after using it and then again, always the night before....My breaker is not easily accessible under the console....so, I always unplug.

bernieNC Posted August 9, 2018 Report Share Posted August 9, 2018 FYI Power Pole Tech just told me power should be disconnected when charging. Link to comment Share on other sites More sharing options...
