Helix 10 not displaying 2D sonar

[cgb24@yahoo.com]

Hello, I have an Ultrex 80 mdi ipilot link trolling motor and a brand new Helix 10 chirp DI mega SI mega gn4. The 2D sonar and the Di images are not showing correctly. 2D is just black and it reads 1200’ deep. DI reads the same depth, but I can get it to work if I manually set the depth. I have the Built in HW MDI+ transducer selected on the Helix. I also have the MKR MI 1 adapter cable installed. I checked the battery voltage at the Helix power inlet. It was 12.6 volts. The Ultrex has only been used about 20 times, so I doubt the transducer is damaged. One thing that could be wrong is that I pinched the transducer cable coming from the trolling motor. I replaced it with cable number 490507-2B 5121. The original cable was 490507-2B 1821. Is there something I’m missing? Is there a setting I need to change? Any advice would be appreciated.
