i’m replacing my transducer due to Failed paddle wheel and temp sensor. Plan on using old wiring, cutting new wire off and connecting with butt connectors and heat shrink tubing. Any reasons why this shouldn’t be ok?
Jerry, I replaced an Airmar DST800 Analog Triducer (Raymarine p/n A22154) last month. I would have dearly loved to use the new cable but try as I may I could not get the old wire to budge. It was secured under the cabin sole in at least several places and it was also secured behind the bullheads to the display head. I finally bit the bullet and cut the cable. Airmar requires the use of their splash proof junction box (Airmar p/n 33-035) or the transducer warranty will be void. I contacted Airmar and asked about splicing using various methods. They responded recommending that I use an Airmar inline cable slice. Here is an example of a 6 wire splice that you could use. It is very small and very easy to put together. Rated IP67Any reasons why this shouldn’t be ok?
No not at all. Everything is good. Temperature is very straight forward. Calibration of the speed is somewhat subjective as the transducer is certainly not linear over the full speed range even for a sailboat. I have it set for exactness at my 6.1 kt cruising speed and live with the inaccuracies at lower and higher speeds. The one thing I was more concerned about was integrity of the RF shielding on the depth sounder cable, which you do not have; but, even that seems to be a none issue.Did you notice any resistance issues on temp and speed that you couldn’t calibrate out?
