Was mowing with my MMM and without any dash warning the tractor shutdown. LCD dash display went completely blank. Of course it will not restart in this condition. I can turn the ignition to the "ON" position but the LCD stays blank, nor do any indicator lights come on. Also, the headlights or emergency flashers do not work with ignition "ON". I do hear the clicking when I turn the ignition ON though. Battery is fine (hooked up to my truck battery to test) and all fuses up front around the battery are good. Any ideas what to check next? It's a 2024 model.
