Thread: Helix 10 sonar gps gone haywire

I don't know if this is coincidence or something else but I had something going on with my navigation screens on my MEGA 9 yesterday afternoon. Instead of showing the water temp, it's showing a number over 100. I don't know if that's a bearing, or an innacurate temperature. I could have messed with a setting causing the bearing to show up instead of temp. I didn't pay enough attention to it to see if it changed much depending on where the boat was. On any other screen other than a map screen, the temp shows up.

Also during the same time span, out of the blue, the autopilot function on my Ulterra started acting crazy and I could see what it was doing on my Helix screen. It ended up driving the boat in a small circle and while that was happening the green line that normally appears on my screen showed up as a black circle. The green line was gone. I turned the autopilot off using my remote then turned it back on and it worked fine the rest of the afternoon.

My batteries are new and I charge them via an onboard charger after each trip out.

Maybe it was just a bad Humminbird day.

Mine lost all sonar screens, to test it, I hooked up an external transducer that I had and it works fine with it, so it has to be the cable or the motor wiring, I hope it's the cable.

Update....... Checked adaptor cable with ohm meter and it checks good, so now I have to check the trolling motor wiring to see if I have pinched a wire in it somehow. Always something.
