Question about Lowrance Marine Electronics

Open Question


Hi, I have a lowrance X-85. when I turn it on, the speed and temperature sensor (model ST-TBK) indicate the speed and temperature on screen and all is right. But after fifteen minutes, the sensor does not work well because it indicates the same temperature even if the temperature has changed and the speed indicates 0 mile per hour. Then I turn it off and turn it on afterwards and it still works well for only fifteen minutes and the same problem occurs.
Can you help me please to fix this problem?

SOURCE: Globalmap 2000 sonar not responding

Not enough info to diagnose your problem. It sounds like a networking problem. I couldn't find a manual for the sam-st module so I'm not sure how you have it hooked up. Typically with these devices only one would be hooked up to the SONAR module, and it would then share the data with the other display via an ethernet or NMEA2000 network. The erratic behavior of your bluewater could be due to some sort conflict with the current coming from the GlobalMap2000. Do you get the same problem when the 2000 is turned off? Have you tried running the GlobalMap2000 with the bluewater turned off?

You need to check first that the output drive semiconductors aren't overheating and malfunctioning, this indeed sounds like a thermal issue? If not that then check the motor, it maybe overheating? Also I am fairly sure you have a? bad battery, too, this is evidenced by what you relate and to how the battery acts when used and recharged. I suspect, that these batteries, well one or both have developed a "Memory" and as such are failing, to deliver full power and recharge properly. I think new batteries will make things work properly again.

Does the x510c have a speed and temp transducer or just the paddle seperately

Hi Rick

There is only one transducer. for speed/temperature. From page 2 of the owner's manual (see link below)
"A single-frequency with built-in temperature
sensor is packed with the X-510c"

Hope this helps and happy boating!

Hi, whenever I power off my lowrance 125 it defaults the settings and I constantly have to change them every time I turn it back on, also the speed read out on the top left remains at 0 kts, however I do...

These units have internal batteries that power a small bubble memory that remarks your settings. I would conclude that this battery is dead. The result being your unit forgets your settings every time you turn it off.
Possibly a faulty speed wheel on your unit as to why the system no longer registers speed.
Try recalibration the speed.
Above is a link to a PDF for your owners manual.

The additional wires are for NMEA data transfer to and from other devices and sensors like distance, speed, depth, temperature and NMEA 0183 sentences the unit will use when connected to a VHF radio or other NMEA 0183 device.
