Nexus Classic Instrument problems/fixes

Recommended Posts

I have a Nexus Classic network, server w/ digital Depth, Speed, Temp, Wind, Multi and A_Pilot . I hate to give this system up as it has worked flawlessly until this year.

A friend who helped me do the bottom this year (can;t complain to him) and not knowing any better painted over the Depth Transducer with bottom paint.  After splashing the boat I had no sounder return on the depth instrument.  The classic sounder lets you pull the transducer while wet so I pulled it and sanded off the paint.  Did the sanding kill the transducer as I still have no depth readings?

Secondly, I noticed this year that my wind instrument is not displaying realistic wind speed, i.e. 4.7 kts in what is truly 15 kts actual using a hand anemometer.

Are the wired Garmin instruments and transducers compatible with the 4 wire Nexus Classic Instruments?

Thanking all for any and all replies.

Probably the best thing to do would be get the Garmin GND10 black box and Garmin/Nexus wired wind transducer.  The bearings in your wind transducer are probably shot.  The replacement setup will put the wind data of the Nexus bus (4 wire interface you reference).  It also will give you a NMEA 2000 bus to interface other stuff in the future.  My guess is the depth transducer finally died from age.  If you install the GND10, you could install a depth transducer with a NMEA 2000 interface. Do you have the 43 or 52mm transducer?

If you have the 43mm transducers Garmin sells replacements.  The GND10 recommended by WHK works great connecting my NX2 instruments to the chart plotter, it speaks both ways.  Might be obvious but did you check the transducer connections at the instruments? Any corrosion or loose wires?

Looks like if I go for the gnd10 black box bridge it will open all sorts of opportunities for me.  Thanks guys.

Where should I be measuring the depth transducer, I dont know which one I have?

Are we talking about the thru hull cylinder or the removable transducer itself?

I have the 43mm transducer and it requires a 43mm or 1 11/16" hole in the hull for mounting.  The thru-hull cylinder is 42mm x 86mm according to the installation manual.
