Hello, I have a Helix 7. I am looking at connecting it to my 12V marine battery using a 1 gauge copper ring terminal. I am using a 14 gauge wire and plan to solder it to the ring terminal. Can someone tell me if this will affect anything with the fish finder. I spoke to hummingbird and the person I spoke to was not at all helpful. She said that Hummingbird recommends just wrapping it around the terminal. Thank-you
