Your trolling motor wiring coming off of your batteries you will see in line 50A breakers, there is a small push button on the side of the breaker, if its popped it will have a little bit of resistence pushing it back in. Also check your connections to make sure nothing came loose. After that, you should check the plug with a multi meter and verify your getting 24V at the plug (or 36v if you run a 36 volt system), if you have voltage at the plug, then your looking at a trolling motor issue, verify the momentary/continuous and on/off switch didnt get turned to off, if its in the on position and still no power then id bring it in for service, your troller should have a 2 year warranty.
