So, I wasnt getting enough voltage to my graphs, like 10 volts at full charge, with a brand new Sears starting battery. In talking to Humminbird, they suggested new and bigger wires. I ran 10AWG wires to the front and dash graphs and connected them direct to the battery, (with a 3 amp fuse of course) and that problem is resolved am only losing .1 volts now. However, my forward/reverse shifter seems to shift into gear harder than before. I guess I could have inadvertantly ran a wire through the shifter? I thought they were a sealed unit with a sealed cable? Any ideas would be welcome. Thanks.
