trick worms Posted June 6, 2017 Posted June 6, 2017 The transducer cable that goes into my fish finder was sliced open by my trolling motor prop and won't read anymore. Any suggestions for a fix? Thanks Quote
Super User J Francho Posted June 6, 2017 Super User Posted June 6, 2017 I think the only fix is replacement. Quote

It's shielded, and you have to solder all the connections. Some do have repair kits - try a search for your model. As far as I knew, you don't want mess with the cable, like alter the length. Quote

The only part of this that is correct is the reference to the wires being shielded. I have spliced many without incident. The length is absolutely absurd....makes no difference what length the cable is. 1 Quote
Super User WRB Posted June 6, 2017 Super User Posted June 6, 2017 Several ways to repair a damaged TD cable depending on your skills. TD and cable are a replacement item and readily availble, that is your best option. If you know how to solder wires the cut wires can be repaired. The shielding isn't used as a conductor like a coaxial cable so repairs can be done without impacting the impedance, it all about apaturees and resistance. You can simply wrap tin foil over about 3" of shielding and tape wrap it. The biggest issue is sealing the repair from being submersed water. Tom Quote
Super User DogBone_384 Posted June 6, 2017 Super User Posted June 6, 2017 If you can solder wires, you can repair it. I'd use double walled shrink tubing for the inner wires and the outer shielding. Double up your final shrink tubing for the outer shell to ensure it'll keep water out. I get my shrink tubing and wire from DelCity.net Good luck. Quote
trick worms Posted June 7, 2017 Author Posted June 7, 2017 I have no idea how to solder wires. The wires itself don't appear to be damaged, but the black cover is opened and they are hanging out Quote
OperationEagle Posted June 7, 2017 Posted June 7, 2017 I used liquid plastic sealer that I found at Home Depot. You brush it on and it tries as a layer that seals the area. Worked like a charm. Found it on an end cap near the electrical area. Quote

I'd be willing to sacrifice my TD to try this for my kayak unit. The length of the cable is absurdly long. Good description. Quote
Super User Scott F Posted June 7, 2017 Super User Posted June 7, 2017 You should be able to attach a male/female connector to the damaged wires or use one to shorten the length of the cable if that's what you need. The transducer cable on my Terrova has an adapter cable to connect it to my depthfinder. The cost for the connectors is not cheap. It could easily cost as much for the connectors as for a new transducer. The attached picture is for a connector with 10 wires, but smaller connectors are available. Quote
Super User Wayne P. Posted June 7, 2017 Super User Posted June 7, 2017 AIRMAR transducers are "universal" unless specifically produced for a certain sonar brand. All the "universal" ones have to be spliced to an appropriate connector. They have a splice block that does not involve soldering or crimping on pins. There are similar ones with more connections: http://www.airmartechnology.com/uploads/InstallGuide/17-037-01.pdf Quote

Specifically designed 'water tight' splice connector I get from AU. I'll grab a pic and details when I get to my shop later. WARNING!!! They are pricey....but, if you are dealing with a high dollar XDCR, it is worth it. Most OEM ducers are far cheaper to replace than to fix. 1 Quote

Super User J Francho Posted June 7, 2017 Super User Posted June 7, 2017 That is actually worth every penny. Thanks a million. My next project is to clean up my kayak installation! Quote
