Humminbird not shutting down
Here lately my humminbird 899 si not wanting to shut down. I push the button it counts down till shutdown comes up on the screen then it go's off and then comes back on. It then stays on no matter which buttons are pushed until I go to the fuse at the battery to kill the power. I have check the battery power and 12ga wire was used to power unit which was sortered to wires. Never had any problems up until here lately. Have any of y'all had this problem and how did you fix it other than buying a new unit which I can't afford at this time.
