Transducer wiring for l365

[Jhabuda88]

so i have a raymarine l365, and my transducer cable got cut. i called gemeco, raymarine, and any parts i needed for the transducer is obsolete. so i need help to fix it as i dont have the money for a new fishfinder. yesterday i soldered all the connections together, my speed works on the monitior, but my temp and depth is just flashing, and not working. so tell me what type of solder, flux, i should use, and pretty much anything else. also i had this foil wrapped around my wires, do i need to put that back on and what is it used for? t

thanks for all your help.

You need to use rosin core solder. A separate flux is not needed. Each solder joint needs to be covered with heat shrink tubing and then the entire repaired area covered with heat shrink. The foil is called a shield and its purpose is to help prevent electrical interference from affecting the display. It must be installed but that's difficult to do. You can however, wrap the joint area with aluminum foil before heat shrinking the area. Just make sure the foil contacts the foil at both sides of the repaired area. When you repair the wires, stagger the joints so you don't end up with a big ball in the repaired area.

Awesome, so this is gonna be a tedious job. So when I go to solder the joints do I go end to end, or can I put the connections on top of each other.

Ok so I did it properly the way it was mentioned above, but my depth is still flashing, any ideas?

I have no idea what your soldering skills are but laying one wire on top of the other or end to end is not the way that should be done. You cross the two ends and then twist each end around the other then solder. Remember to put the heat shrink tubing on one of the wires first so you can slip it over the joint after soldering. Are you sure you don't have a short or break somewhere else in this cable? You haven't mentioned if this locator worked before the cable was cut. Next, you do have the boat in the water when testing don't you? Locators cannot read through air.
