I checked and the input power is 12 .04 volts at the plug. Is there and internal fuse. I understand that Lowrance no longer services the unit. Is there anyone out there that can service this unit? I was told by Lowrance the only thing they can do is offer me a rebate on the next unit. Does anyone know if there are service manuals or wiring diagrams available?
