HB 565, crushed and cut transducer cable in at least one place, temperature does not work at all now, depth seems to, but other details like fish and structure seem intermittent. Can I cut out bad section and splice back the cable or am I looking at a new transducer? Transducer mounted on trolling motor. Looking at another route for cable.
it can be spliced simple canepole did one for me cut the bad part out and stager the splice iner and outer srinktube both
You can splice, but the temp will not be correct. When you splice a thermocouple wire you make a "cold junction thermocouple" it will read the temp at the junction point and not at the ture test point. But the sonar should work.Quote:

We don’t use thermocouple wire in our transducers or temp sensors. We use a standard Thermistor and regular wire. Unless you make a resistive solder connection splicing the temperature side of the transducer cable should not make any noticeable difference. Just make sure whoever splices the cable reconnects any noise shielding as well than make sure its all sealed well. I would not splice it if the break would be below the waterline or is in an area where the cable needs to flex.
Might want to finish the job with liquid electric tape. Good stuff. Used it around salt water with good results. Tape or shrink as usual, then clean and coat with the liquid.
thanks guys, my 565 was fogging up so bad I sent it back to HB for repair, sent transducer along to be checked out, when I get it back I will attempt to splice it. the liquid tape sounds like a good idea where do you get it?
Walmart or any marine supply store carries it.Quote:

Dual wall heat shrink is made for watertight sealing. I use it on my ROV robots and successfully dive 1 atmosphere with no leaks.
Google up dual wall heat shrink and read the specs.;)
Also,
If your break is in a flex area, if you can,,,, shorten the cable and splice in a non flex area. In flexing areas, I use spiral wrap. Good dodo that spiral wrap. In fact, I wrap most of my wires in the spiral wrap. Looks good and is protected from me.
Nothing special about transducer wires, so don't believe any bullchips.
Is that that stuff that has a coating inside that seals everything as it shrinks? The Navy yard uses it but not sure what its called or how small it comes. I've got a piece thats about 1" ID before its shrunk.Quote:

I highly recommend this over the liquid tape stuff.
Yes Bill, It is self sealing.

My metal gas tank ('57 era) sliced up my transducer wire. I spliced up the wire and the sonar worked great, however the temp didnt. This past winter I respliced, same result. I bought a new transducer, still no temp reading. What ever happened took out the temp in the Hummingbird unit. It constantly shows 99 degrees. I hope you dont have the same problem.
Anybody know how to fix the temp reading on the unit?
Send it into Humminbird to fix.
Thanks Greg. I sent you an email.
Its a PMax 220, not sure it will be cost effective to have it fixed.
Just my opinion here: I would save the repair cost money towards a newer model sonar unit. Not that the PMAx isn’t a good unit for what you paid for it; it’s just that there are other sonar and sonar-GPS combo units that would give more capabilities.
I you lived here, I would fix it for free. I guarantee my work.:) I have been "fixin" since the green box first came out.Quote:

I have some electrical experience (3 years as an electrician), and some electronic experience (high school 20+ years ago). My youngest son is an electrical engineering student (jr.) and I am sure he could find his way around the circuit board, if he knew what to look for and repair.
