Our Tridata display has lost log, boat speed & Water temp, it just has dashes where the numbers were. How do we find if the problem is with the transducer or the cabling?

Welcome to Justanswer!

 

The first things to check would be - Make sure corrosion has not gotten into the connector at the main unit, and at the transducer - if all of the pins are intact, you will need to test the cable.

 

Normally in a situation like this, I would suggest checking continuity between all pins at each opposing end of the cable (at the transducer and the main unit) - this will verify if the cable is still good - However, without the right equipment, this can be a bit tricky.

 

If you have a mulit meter with a continuity tester, and a partner to help you out (along with some 17' test leads) this is an easy test.

 

Otherwise, about the only way to test it would be to substitute a new transducer in place of the old one.

 

If you have any more questions, or need assistance, I can try to talk you through testing...Just let me know!

 

-Josh

OK thankyou for that, we can dig up a multi meter, but I'm not sure about testing contacts on the transducer end- it appears to be sealed..... Then it goes into a conduit....
Marine Electronics Expert: Josh C, Marine Electronics Installer replied 11 years ago

what make and model number is XXXXX unit -( should be on the main unit) I will see what I can pull up on this end.
