Question

947c was working fine and now it's not working at all and it states that the "transducer is not connected". Ran a diagnostic on the 947c and it states that everything is working fine. Bought a new Transducer and it still says that the "transducer not connected". Checked all wires and connections and they all seem fine. Any suggestions?
