RD- 30 Help

[Fishcakes101]

I have an older RD-30 that reads SOG and other parameters but no longer reads depth or water temp.
Any help or suggestions would be appreciated Thank you

If the RD30 is powering the depth sensor, someone might have turned off the POWER OUT setting or they swapped the two 7 pin cables on the back of the unit by mistake. The smart sensor would normally go into the AUX port.

I agree with Sparky. If the wiring is correct and power out setting is ON, then it could be that the transducer itself is damaged. SOG would be coming from a different source. RD30 units work or don't turn on in my experience. If not a wiring or setting problem, then the transducer should be tested because it would be the most likely failure if there is one.

Thank you, I'll check it out tomorrow. Could the transducer be covered with marine growth ? Fishcakes

Marine Growth wouldn't stop water temp.
