Unfortunately the transducer does not have free ends that are loose at the transducer end. That's why a wire tracer is difficult to use from the transducer end. But I definitely know and see where the cable goes prior to entering Garmin display. So once Garmin support gets back to me I will take the cover off the adapter box and check out the connections. I think if the adapter box is okay and connections are tight I will have to figure out the power sources close to the transducer cable and probably use some ferrite pieces on suspected power cables.
