We have a 2011 RT 25SC which was new to us last year. 400 hours on the boat. Last fall when pulling the boat for the winter both thrusters were working. This spring neither will work. I have tried to trouble shoot the best I could but do not seem to be getting anywhere. The bow and stern thruster are both powered by a single dedicated battery. All of the batteries are new and fully charged. I can confirm that there is 12volts to both thrusters. The large fuse for each battery appears to be good. There is power to the controller. However the controller will not turn on when either "on" button is pushed and no light. A working controller was substituted for my controller and no change was detected. There is no noise (i.e. relays clicking, etc.) from either thruster. I read somewhere that the windless is on the same circuit. The windless has power and works. I'm not sure what my next step should be. Any help is appreciated.
