I have a T905 depth sensor with a T121/122 hull transmitter as part of my wireless setup which includes a wind speed/direction sensor and 2 displays One display is for for wind and the other is a multi-function display. Last year the depth display stopped working - it would always show 3 dashes, nothing else. I assumed the sensor had gone bad. I purchased another T905 and installed the sensor only to find that my display still reads --- for the depth.
I know that the hull transmitter is part of my network because when I switch off power to it, the displays inform me that there is no voltage going to it. I have tried testing the connections on the hull transmitter for voltage, but I get nothing, no matter the combination of wires I choose (blue,black,gray).
How can I verify that the transducer is working and that the depth connection for the hull transmitter is working? Having already replaced the transducer, I do not want to throw good money after bad.
Thanks
