Minn Kota cutting out at higher speeds

I have a Minn Kota 4.3 24v system.  Runs fine in calm conditions, but when it gets windy and I have to dial up the speed to move against the wind, my inline breaker trips.


What do you think the likely culpret is?  Too light of a breaker, or power wires too thin?

Thanks.I have a new marinco plug on it now but as soon as it goes I will replace with the battery tender plug.

Agreed, the plug is likely the culprit - a bad connection increases the resistance, which in turn causes heat and melts the plug.

Replace it with a battery tender plug. Best one on the market.

Put a ipilot on my 98 smokercraft a couple years ago. Boat was wired for and had 24 volt bowmount on it when I bought it so figured all was good. First year with ipilot I had same problem would kick out at higher speed when windy and surging. Checked everything and no problem. The next year talked to local marina. Original breaker was to light for the ipilot. Think I had 50s and switched them to 60s? This year runs like a dream.

Thanks.  I'll pick up a multi meter next time I'm at Fleet.

Something in your wiring is failing when you generate a certain amount of heat in your set-up. I had a plug do this on me before I upgraded everything on it.  Bypassed the plug and wired it direct and problem solved. 

Get your hands on a basic multi-meter. Those things are invaluable for so many reasons. Check resistance levels throughout your system and isolate the plug.  Check the wiring...then check the plug by itself. Also check voltage levels before the plug and in the plug. 

The other possibilities are that you have a weak wire somewhere in your run which exposes itself when heat is built up causing it to cut out. Of course make darn sure your connections at the battery are rock solid.  

If it is in the wiring you might want to consider re-wiring the thing and if you do step up a size in wires. If they are currently building up heat then by going a size bigger you'll have more surface area on your wiring to dissipate the heat.  

I'd still get those batteries load tested just to eliminate them as a culprit. Most auto parts will load test batteries for free or you can pick up a load tester at a Fleet Farm for around 30 bucks.  While not as invaluable as a multi-meter, having your own load tester if you have a bunch of vehicles around is a good investment. My parents have a farm and the day I bought a load tester is now looked upon as one of the best tools anyone has ever purchased.

jc,

While I have a 12v system, I do have two batteries that I alternate between.  The motor does it with both batteries.  Thanks for the input though.  Any advice is appreciated.

Bugle, I have a 24 volt terrova that did the same last year. I found that one of my batteries went bad. When I replaced them with new the problem went away. Not sure if you checked your battery, but that might be your problem. Good luck.

I have a 55lb 12v PowerDrive V2 on my 16’ aluminum boat that I use primarily for trolling. It’s a bit under powered but gets the job done if I can troll with the wind/waves or if I'm in calm conditions. When I’m in a crosswind and have to turn up the power at or past 8, it cuts out. I get three fast beeps and the motor shuts itself off. The remote stays on but reads 0 for power. I can turn it right back on at a lower speed. I don’t have to reset any breakers, just turn the motor back on. Any thoughts?
