My trolling motor is 24v and on the positive battery cables there is a distribution block that has a reset button. No big issue until I put the trolling motor on hi. When I put it on hi and run it for about 10 seconds or more those blocks get hot and the shut the trolling motor off and I have to get back there and hit the reset button. My question is why does it do this and are those blocks necessary or can I just run the positive cables straight to the batteries? Thanks for your help
