Wiring locator to starting battery

8 posts in this topic

It's probably been asked before, but my father-in-law and I are having a debate.

Would you wire your locator to the starting battery to avoid interference from the trolling motor? He claims that it won't drain the battery too much and that driving a mile or two to your spots will charge it back up. What do you all say?

It will work but there is a trade off. That drain from the electronics can be an issue, especially if you stop and fish a spot for an hour or two. And the motor starter isn't the only thing that takes current off the starting battery. Running lights, live well and aerator (these have a fairly high current drain), bilge pump, night lights, etc. all take current. Do a little night fishing for a couple of hours and then try to start you're motor. Hopefully you won't have drained it down too much and you don't have a fussy motor to start. That's why I'm installing a second deep cycle battery just for the electronics and trolling motor emergency back up.

Thanks guys. I finally got the boat out last night to try out everything. Seems I have a "noise" problem with the locator. The Lowrance rep told me this morning that I should wire the x15 directly to the starting battery and that might take care of it. Otherwise I have to try some other tricks like resistor plugs. I won't be able to get out for a few more days, so I hope that does it. Otherwise I'll be scrambling before opener. If anyone else has great advice, let me know.

Wiring it to its own battery will solve the problem if you can do that. You will get interference if you have it wired to the same battery as the trolling motor.

Thanks. The key thing I forgot to mention was that the problem was occuring when running my big motor over 10 mph. I wasn't running the trolling motor at that time. He claimed that I didn't have a good ground since the trolling motor wasn't in the water. But I'll try to bring a portable battery next time out and hook to that to see if that takes care of it.

Is also sounds like a possible transducer placement problem. Try to take a look at the transducer when you get the speed up and see if there are any obstructions from the boat. You could be seeing bubbles on the screen?

I had the same problem and before I messed around witht the battery I adjusted the transducer like D-Man said and that fixed the problem. My guess is the transducer isn't getting an even flow of water over it when you are going over 10 MPH. Remember, in most boats transducers need to have the back angled down.ScottS

    • That is what I am trying to figure out.    Considering the party in the white House the only reason he/she got the sentence changed has 100% to do with his/her corporal Klinger syndrome.    And if that is the case the President should just walk away today before he causes any more harm.
    • The US gets Assange this way. Not difficult to understand.
    • It has a slight liberal bias: all major news media lies between the political ideology of a typical Democrat and a typical Republican. No outlet is going to intentionally dissuade 30% of the market, it's just bad business. With regards to Trump though, he has made an enemy of the press. It has little to do with his political affiliation and everything to do with his confrontational attitude. See this "come at me bro" of a statement from the Press Corps. Note they welcome Trump to sue them for the so called "fake news", probably because they are confident in the accuracy of their articles. Also realize that it is entirely possible for something to be accurate and biased: which is probably all you will see in Trump coverage from here until the end of his Presidency    
    • So we support intelligence depts now?
    • You mean fake Bruce Springsteen.  The real one is a librul and the fake one didn't want to urinate on the bed of the real one.   I'm sure Trump wanted them to play "Born in the USA" like all the other politicians that have no clue what that song is about but like the chorus.  
    • I'm trying to wrap my head around this one. Obama truly is a bigger POS than I thought. Good, God this is bizarro world. By commuting the sentence of this freak show, it's like burning down all the intelligence depts. Why do we have laws? 
    • So Obama is mad at the Russians for hacking and Wikileaks for publishing the hacks yet he just Pardoned Chelsea Bradley Manning who stole secrets and gave them to Wikileaks   This is a real WTF moment.
    • You failed to post the very next part of that very article:     You never patted Obama on the back for any of that oddly enough.    http://www.reuters.com/article/cbusiness-us-gm-tech-center-renovation-idCAKBN0NZ19920150514   So either congratulate both or congratulate neither.
