My ST 40, only two years old, now displays only dashes. The manual says either the face of the transducer is fouled or the cable is bad. The transducer is mounted inside the hull in an oil bath so fouling is not the issue(hull is clean). I wanted to know if anybody knows a way to test the cable by maybe taking readings with an ohmeter across the terminals, before I go through the trouble of pulling it all out and purchasing a new transducer.I have sent an E-mail to Raymarine, but I am sure they will be eager to sell me a new transducer.
