My 2013 Case SR250 was dead the other day. I used a jumper on it to unload a trailer quick and parked it again. Came back out the next day to start and same issue. Only now even with the jumper on it, it will not give power to the ignition. I press the power button and then it lights the start button up as usual. However the ISO/H controls light is not lit up as it normally is and when you press the start button, nothing happens. I've check fuses in the cab and tried unplugging battery. Out of ideas... Thanks
