I want to install one battery on my boat. I want to run my trolling motor and my fish finder on the same battery. I will also have some small leds but won't always be on. And I have a gas motor so I'll only use trolling motor while fishing. Also will have sole panel trickle charger on battery at all time. Will this work. Will trolling motor interfere will my fish finder? Thanks.
 
You will get feedback to fish finder when you operate the troller

Could try something like this on the fishfinder.

I run all my electronics off one battery and mines fine. I have a min Kota maxum and lowrance 5dsi that are on together all the time and occasionally have my running lights or bilge pumps on also I've never had a problem
 
Yeah, I've heard the same thing about interference but I have run two different fish finders on my boat and use the same battery for my gas motor, trolling motor and sonar and everything plays well together.
 
Go for it. I've run numerous FF 's off of the same battery and haven't noted any interference.

It may affect some FF's, but more likely, it is a FF manufacturer's lawyer's way of protecting the manufacturer if their unit does have any issues.

you might get issues if you run the FF power wire parallel to the TM wires in close proximity to one another, otherwise you should be OK.

What he said. I use a fuseblock to isolate circuits. They're not too expesive:

Agree with the posts just a above. The interference would come from a bleed over from wiring on circuits that run parallel to one another. Running them on the same battery should not pose an issue. If the cables are kept some distance away or they are shielded, you should not have interference issues unless you have issues with current draw.
