[CA11] CP470 not recognizing transducer
I just added a used CP470 with a new B175L chirp transducer through a single transducer cable since I currently only have the one low frequency chirp transducer. Originally, the CP470 recognized the transducer but after a couple hours it stopped recognizing it. After some research, I realized I needed to add the additional grounding point on the CP470, which I hooked up today, but it still does not recognize the transducer. Did I mess up the CP470 by not having the additional grounding point hooked up? Any ideas on what else I can do to troubleshoot?

additional notes:
- I reloaded the software to the CP470 today with no luck
- the shielding on the CP470 power cable is not grounded
- The CP470 boots with a steady green LED status light and transitions to a flashing green LED light
