    Default Fuse blocks and interference


    So on my ongoing quest to wire my boat, I found that a fuse blocks situation might make things much cleaner. Can a fuse block cause interference or noise in sonar? In my head, no. Because if you have all electronics wired to one battery, the connectors all touch one another which is essentially what a fuse block would do with one power in that is split into separate outgoing wires.

    Trolling motor will be on its own run, with its own circuit breaker and will only be wired for trolling motor. Everything else will run off of the third battery which would feed the fuse block.

    Should be fine as long as you run a good sized wire to power your fuse block. I would still run each depth finder to its own seperate fuse. Pretty simple check, turn finder on then cycle bilge and ariator pumps and check for interference right at the house.

    No bilge or aeration. G3 1652 Jon boat. Each sonar will be on its separate fuse.

    Your good then. Main thing is good tight connections. If it was me I'd get one that has screws for each connection not the push on spade kind.

    I just installed this fuse block in the back of my boat next to my accessory and cranking battery, I ran 10 gauge wire to front of my boat for new Humminbird Helix. System works good

    I bought this to help with bunch of wires at battery. Works pretty good so far for me.

    Remember that a fuse in the electronics circuit is to protect the entire circuit - not just the electronics ...

    It's a good idea to install the Fuse Block as close to the battery as possible to protect the entire circuit ...
