It looks like the camera use an RJ 45 Plug to transfer the signal and power to the AV and power plug connectors. All you have to figure out is which pin goes where.
Power uses 2 pins, Video uses 2 pins and Audio Uses 2 Pins.
So you can get a network cable with an RJ45 connector at the end and connect the AV and power plugs on the other end. I just dont know which pins are witch.
Have you checked the transducer for damage, or the wire to it. Also check the connection on the unit itself. On my Humminbird there is a Demo Mode. See if yours has one? If Demo Mode works, then it is the transducer.
My experience as a user is that turbulence around the transducer can cause mine to flash and the depth to remain static.Is your fault affected by speed? Sounds to me that you have a faulty connection causing the transducer to "not register". I'd check connections and also the integrity of the transducer. Hope that helps...
Best of luck
flip locking flap on connector away from the gold pins. Slide the ribbon cable into the connector on the side with the gold pins as far as it will go. The ribbon goes face down with its gold pins facing down. Then using two fingers flip the locking flap down and toward the ribbon cable. It should click. Be careful, if you snap the flap it is game over.
Question: What are the extra wires used for on the power cable for my fishfinder?
I found this on the carmin website under questions and answers. I think your cable is ok to use according to this. -->
Not all of the wires in the harness are required for use. To connect the unit to the power source, only the black & red wires are required (black to ground, red to positive). Here are descriptions of the other wires in the harness:
The Blue wire is used for a NMEA data out connection to another NMEA compatible device. The fish finder outputs NMEA 0183 version 3.01. The receiving device must be compatible with this format and looking for the NEMA sentences DPT, DBT, MTM, or VHW.
The Brown wire is used for a NMEA data in connection to receive data from another NMEA compatible device.
The Yellow wire is used to connect to an external buzzer or alarm to alert you to any alarms which have been set to sound on the device. The Yellow GARMIN wire connects to the negative end of the external alarm. The positive return on the alarm will connect to the red positive wire of GARMIN.
The green, white, and any other colors present have no connection purpose related to your fishfinder. The 18 Pin connector wiring harness is used by several other devices which utilize these wires.
If the device is only being connected to power & do not require a NMEA interface, PC connection, or external alarm support, only the red & black wires are required.
