Which Battery for Graph?

3 posts in this topic

My current depthfinder is run from the trolling motor battery (up front) with the starter battery running all other electronics (bilge, livewell, and running lights). I'm upgrading the graph and figure now would be the time to change this if that's not the way it should be. Any problems with running the graph and trolling motor from the same battery? FWIW - I don't use a trolling motor all that much ... mostly drifting or trolling with the 40 HP.

I was advised by the dealer to leave the trollng motor on a circuit by itself. That way you wouldn't get interference on your sonar from the trolling motor. Not an expert, just what I was told.

See this thread: Locator Issues

You'll have similar issues if you run the trolling motor while you're using your locator.

I'd run a wire back to the battery with an inline fuse.

      Thanks for the ice report, Sculpin.  With the weather forecasted for the upcoming week, I'm sure I'll be up there next weekend, hopefully walking out from the northwest side.   van, yeah, I hear you.  I've been up to LOW a few times, and it is very fun to know there's the chance of catching a monster....but driving all that way for a bucket full of 12'' fish?  Not my cup of tea. I'll save the money and buy three dozen T-bones to make it through the winter. I'm sure people who know the lake better than I do have done better on the weekends I'm up there, but the reports at the resort we used were pretty similar.    I like the northwest side on ML because it's where we've been for almost 20 years, but it also has close access to sand, rocks, whatever weeds remain, mud flats, transitions, etc. The only thing we don't have up there is extensive gravel.

      I'm curious to see how this works out. Do you plan to keep the battery warm while not is use on the water?
