I have a flashing RED LED with steady 75% YELLOW LED that indicates there is a damaged temperature sensor on the output cord. Has anyone had this happen to them or does anyone know how to repair the problem. I'm pass the warranty of course so, I'm not apposed to opening the unit. I just got back into fishing so I don't mail it off for ever. I'm disappointed for spending so much money on a name brand product and having it go bad. Fortunately I can charge the deep cycle batteries, but I can't keep the cranking battery topped off.
