Question about Lowrance LCX-15MT GPS Receiver

Open Question

LCX 15 MT GPS Depth Finder

I have 2 LCX 15 MT GPS Units on my boat and the unit on the console will tell you when turned it on that the program is corrupt and to contact your provider. I did contact the provider twice and about all I got from the support department at lowrance was that parts were hard to come by for this unit. The problem with the unit is that if you turn the unit off there is a flicker on the screen and then it turns off and if the unit is turn back on for an hour or so with the corrupt sign left on/unit turned off and back on the unit will usually come on correctly.

Hello
If the GPS works and sonar section does not work at all, check the followings.

1# Check the power cable's connection at the unit. Also check the wiring

2# Make sure the power cable is wired properly. The red wire connects
to the positive battery terminal, black to negative or ground
3# Check the fuse.

4# Measure the battery voltage at the unit's power connector. It should

be at least 10 volts. If it isn't, the wiring to the unit is defective, the

battery terminals or wiring on the terminals are corroded, or the battery
needs charging.
Check whether there have any wiring break, loose. During servicing the boat, there is chance to get the wiring of sonar to sonar sensor at the botom of the boat may have damaged. Check these. OK.

Why does my fish finder sieze up when i start my boat?


it seizes up because their is a very hi draw on your battery when the motor is turning over, the starter draws so much power from the battery that it drops the voltage down below what the depth finder needs

Tip

Lowrance LCX power up problem


On Lowrance LCX-19 and I would assume other LCX series units.
The T3 Transformer shorts out and when the sonar kicks in it causes the unit to go over current and will eather cause the unit to reset and start again or blow the fuse. If you have the ability you can re-wind the transformer.

The primary is 46 turns of 24awg inverter duty magnet wire,
The secondary is 164 turns of 26awg inverter duty magnet wire.

Be sure to keep the same winding direction as what you take off as it may be phase sensitive. Be sure to use mylar tape between the primary and secondary windings.

Just a note this board has very heavy power planes and is very hard to solder/de-solder on.

Gps error message "gps module not responding"


Check the connectors and wiring between the GPS module and sonar unit. If it's an internal GPS module yo may have knocked loose a connector internally.

Transducer is mounted on a plastic bracket to trolling motor. when trolling motor is turned on, black vertical lines appear on my screen. lowrance x107 cdf


Are you utilizing another unit in your dash? If so, sometimes when both units are on and in sonar mode, their frequencies will intefere with each other causing the vertical lines. I would suggest turning your dash unit off or lowering it's Hertz rate from 200Hz down to 50Hz.

Funny story...I saw this same issue on my boat years ago. I had an X102C up fron and an LCX-19c in the dash. I acutally thought it was some sort of man-made structure and spent time fishing it...DOH!

310 c garmin gps on boat not working


Hi, 673king, My Garmin is c330, but I think that all GPS's of this nature are programmed only for roads -- not bodies of water. I haven't updated my 2-yr.-old-Garmin yet for new maps, but what you describe concerning the red question mark is exactly what I get when I am on a road that was constructed after my Garmin was programmed. Since the GPS can't find the road in its memory, it merely has a red question mark until I get onto a road that the software recognizes. It then operates as usual.

Lowrance LCX-19C GPS Receiver Problem


It sounds like you may have to send it out for service, but before you you do there are a few things you can try.

Low voltage can cause erratic behavior. Since you already wired directly to the battery, check the plug for corrosion.

Try unplugging the transducer cable to see if the display still behaves erratically. You wont see depth readings but you should still see the screen going black. If no erratic behavior with transducer unplugged then problem is in the transducer cable or the plug. A common source of failure is at the plug because the added stress of plugging and unplugging cables can cause the socket to twist slightly which can cause a short.

Make sure you have the latest software update.

How to see if your LCX-19C is already using version 1.8.0 software:
  1. Press the MENU button twice on your LCX-19C.
  2. Select SYSTEM SETUP.
  3. Select SOFTWARE INFORMATION.
  4. The software version for your unit is located under the line that says "LCX-19C" (ex. "Version 1.8.0").
  5. If your version is the same version listed above, there is no need to download the software.
If it is lower than 1.8.0 you can download the update from this link: LCX-19C UPDATE
Copy it onto a blank MMC card and install it in your GPS. The GPS should prompt you on how to install the update.

If you need to send the unit in for service click this link: LOWRANCE SERVICE

Good luck!

NO DEPTH READING


Check the finder on the bottom of the boat and make sure the cable is ok?
