Location: Chicago | can't find the original link. I was having problems with interference, i think, with my lowrance up front which was connected to my trolling motor batteries. Put the trolling motor and sonar on two different batteries, didn't work. I finally wired the sonar to my battery in back, still having interference problems. Tried moving around the transducer, that didn't work. every time i put on the trolling motor, the screen blacks out. I know a few others were having similiar problems, wonder if anything worked. |

Location: Chicago | I have a lowrance x71 up front with the trolling motor both of which are hooked up to two 12 volt batteries in parellel connection. When I give the trolling motor some juice, my graph flatlines. The depth still reads but he graph flatlines. Any ideas how to fix? It didn't do that before, just this summer pretty much. Haven't switched around the connections yet, too lazy. Could it be that the trolling motor and sonar are connected to the same battery? Hopefully a dumb question from the electrically challenged with a quick and easy fix. On another note, just got a HD 27 gps combo. depth reading seems to go out everytime i'm in less than 5 feet. Really frusterating considering my x65 never did that and I would be lucky to get $50 for it. Any help would be appreciated. |

Location: Indiana | For losing the depth in shallow water, download the newer software from lowrance and change the settings to shallow water, works very well. I believe there is a video on the upload site showing this process. |

Location: Stevens Point, WI | I would highly suggest switching your fish locator connections to your starting battery. I believe your having interference and once you switch that, I think that will clear your problem. You really don't want to hook the locator up to your trolling motor batteries if you can help it.
As for your LCX-27, mseybert is correct. I did a video clip with Thorne Brothers owner Josh Roundsley on how to correct the depth reading problem in shallow water. He did everything in this video to my units and my units worked flawlessly all week on Wabigoon where we fished five feet of water all week. I even got readings of .9 feet. So follow what Josh suggests in this video, and things should improve!

Location: Chicago | Thanks for the response. hope that works. The more I look into the problem the more I find a lot of people are having problems and alot aren't too happy with lowrance and rightfully so. Hope this works as I have a trip up to Canada in September. Would like to know when i'm about to hit a rock!! |

Location: Medford, WI | Ron, I was going to post a question regarding about the same issue as you've been having as far as your depthfinder not reading the bottom when the trolling motor is being used. However, mine also doesn't read the depth when the trolling motor is past setting 2 or 3. I figure it has to do something with some type of interference.
I tried hooking up the depthfinder and the trolling motor up to seperate batteries, but it still appeared to have the same interference. If the cords for the two are crossing, touching or on top of one another, would this have something to do with it???
I'm a beginner when it comes to electronics, so I'm hoping that the knowledgable can help me out and it's an easy fix.
Appreciate any help guys; Thank You, Jake Bucki |

Location: Medford, WI | Thanks Mike,
It is an external transducer so I'll give that a whirl and see if it fixes the problem. As soon as I have a littttle more money, maybe I'll make the switch to hummingbird as well. |

Location: Chicago | I switched the connections last night so my trolling motor is going one battery and the sonar to the other, i'm hoping that works..i'l'l let you know. i don't want to run my wires all the way to the back battery, i have too many wires going back there. I can't figure it out, never did that before. Seemed to start when I bought two new batteries, for some reason i still get the depth readings though, it just flatllines so i can't see what the bottom looks like. annoying. i'm keeping my fingers crossed that switching the connections to seperate batteries works, we'll see though.
Going to do the updates on my GPS tonight, planning on going out saturday. we'll see on that too. i'm actually just going to change around the functions that the guy from thorn bros recommends, have to get a fresh card to update it. |

Location: Chicago | I'll have to try moving the transducer if my first attempt doesn't work. it's always been in the same spot and I didn't have this problem till this year. I'm definitely a clown when it comes to understanding electricity, interference, etc. |

Location: Chicago | The changes on my X28 HD seemed to work. I didn't updated the software, just changed around the setting that the guy from thorne bros recommended. I didn't have any problems with the sonar not working in the shallow water which was minimal so hopefully its resolved.
No luck with the graph up front though. switching the connections around and still had the same problem, my graph would flatline everytime i turned the trolling motor on. |

Location: Rhinelander, Wisconsin | You should not hook up your sonar or any other accessory that requires consistant amperage/voltage to the trolling motor battery bank. I'd find a way to wire it up to your start battery. A 'bird will lose signal when drawn down by the trolling motor too. It doesn't matter which battery you attach the sonar to in the trolling motor bank, you are looking for problems with that power source.
I'd about bet that's the issue. One battery or the other could be weak, or your trolling motor, trolling motor wiring, or plug could be part of the problem. If the set-up worked before, and you bought new batteries, I'd bet one or the other isn't up to snuff. |

| Run wires to your cranking battery for your motor...Try that out and it should help you.... |

Location: Oconto Falls, WI | I got a new locator (Vexilar) at the counsel early this year, so I moved my old counsel locator up front. Due to having a short lead on my new locator I wired it straight down to my trolling motor battery under the counsel. I ended up having the same issue of it blacking out every time I hit the foot pedal for my trolling motor. So I ended up lengthening my leads and ran the locator back to the cranking battery, and problem was solved.
It appears that if you run your locator wires to the power source receptacle in the front of the boat (if you have one) that also eliminates the interference from the trolling motor. I could be wrong but that is where my front locator is wired to, and I have no issues with it when I run the trolling motor.
I for one would actually prefer to run everything off the trolling motor batteries if I could. I would much rather those batteries go dead than my starter battery while I am out in the middle of a lake. I would imagine if I ran my two locators, boat lights (at night), and my radio off the cranking battery I would run into issues with it dying on me.
