Yes you have to hook up the red wires together to the + and both black ones to the negative, otherwise the antenna won't be supply in current , and don't forget to insert behind the red wire a fuse and a switch to avoid to discharge your battery .

SOURCE: lowrance 522c-gps combo, unit flashed during high

Tranducers must not connected while the system is ON. They are hi-frequency sound emitting devices, connecting it when the mother unit is LIVE, will make the transducer drive inside the device to fail. Here that has been happend I thinks. Just reset the system to its factory settings.


2* The unit asks if you want to reset all the options. Press ? to

YES'ENT. All options are reset, and the unit reverts back to the Map

Page at the 4000 mile zoom range. (Any recorded sonar logs or GPS
data will be unchanged.)

If this process do not help you, your GPS need service. We can't get any schematic diagrams or sevice manuals of GPS devices, as security reason, they will not be published. You must have contact the Lowrance Authorised Service centere at your town to get this device repaired. OK.

How do I fix a Lowrance X-45 fish finder screen?

Hi Bobby

This condition is nearly always caused by a power supply issue.
Carefully check, clean and lube power cable connections, paying particular attention to crimp connectors, fuse holders and so on.

Hope this helps you out.

522c went out on now, replaced with a LCX28c HD head unit! Lowrance said it would hook right up to existing power and sonar hooks up, but after powering the unit up, it shuts off after about...

Sounds like you may have an issue with low voltage to the unit. First verify your battery is in good condition. Connect the new power cable directly to the battery using appropriate fuse and test. If the problem goes away then the problem is with the wiring between the battery and the head unit.

My LMS-522C keeps losing it's position on the GPS.

I'd suggest calling Lowrance.. Those guys are very helpful with step by step support... I just purchased a used boat with a 525c df on it and been troubleshooting some problems with it. Central time zone and best to call right when they open or turn on the phones at 8:15.

If it is normal in deeper water, it is most likely just returning stuff in the water (debris, algae, anything floating around...choppy water can cause this). Try installing the latest updates from

If it doesn't help, adjusting the sensitivity or setting the SURFACE CLARITY option from the SONAR FEATURES menu to LOW, MEDIUM, or HIGH...whichever gives the best results.

Lowrance LMS522c transducer

Probably not. Usually the transducer is made specifically for the head unit it is designed for. More often than not, transducers are not interchangeable, particularly across brands. Also, for best results, you really want to install the transducer that came with your new lowrance. That will give you the best results and sonar clarity.

Hope that helps!
