kickingfrog Posted May 28 Report Share Posted May 28 Checking my trolling motor battery today and noticed some corrosion that I wanted to clean up. What I’m wondering is what is this little black box that is on the connection? Link to comment Share on other sites More sharing options...
kickingfrog Posted May 28 Author Report Share Posted May 28 Figured it is a fuse. Now I'm wondering what amps a replacement should be. Link to comment Share on other sites More sharing options...
porkpie Posted May 28 Report Share Posted May 28 Circuit breaker, I'd recommend a minimum of 60amp. Princess auto sells them, but I've occasionally had trouble with the cheap ones. I generally spring for a minn kota branded one when it's time to replace. Link to comment Share on other sites More sharing options...
kickingfrog Posted May 28 Author Report Share Posted May 28 There's nothing it to indicate what size it is. I can find lots up to 50 amps. I might just clean this one up for now and keep looking. 1 Link to comment Share on other sites More sharing options...

Terry Posted May 28 Report Share Posted May 28 Looks like a thermos block to me so it’s a breaker if it gets too hot Link to comment Share on other sites More sharing options...
kickingfrog Posted May 28 Author Report Share Posted May 28 It's a Mini Kota with 40lb of thrust. Link to comment Share on other sites More sharing options...
SlipperyVic Posted May 28 Report Share Posted May 28 It's a self resetting circuit breaker. The breaker is sized for the wiring it protect. The wiring is sized depending on the size of the load, and the length of the wire. What sized motor and wire are you dealing with? Link to comment Share on other sites More sharing options...

bdox Posted May 30 Report Share Posted May 30 You should be good with a 50 amp breaker if it's only 40lb thrust. https://minnkota.johnsonoutdoors.com/us/support/trolling-motor-installation-guides/trolling-motor-wiring-and-battery-guide Link to comment Share on other sites More sharing options...
Lape0019 Posted May 31 Report Share Posted May 31 Had one of those on my Tour 46lb that came on my bass tracker. If i remember right, it was on 8awg wire and was rated for 40amp. Link to comment Share on other sites More sharing options...
