Wiring a fishfinder to a SLA battery

[alanw]

I have the X-4 Pro, same thing as the X-4 basically. I made a simple wiring harness using inexpensive connectors from Oreilly auto parts, I'm guessing cost around $5. If you use a waterproof box for the battery then you'd need another type of thru-box connector or wire seal. I don't use a waterproof box because, well the battery is already waterproof. I mean why put a plastic box inside of a plastic box? Use dielectric grease on all connections and always use an inline fuse close to the battery. I can post a pic later if you want.

Do what alanW says. and inline fuse should be on positive side and make sure you get a fuse that matches the Fishfinder's manual. Usually minimum 3amp fuse.

thanks guys, pics would be appreciated. i am indeed putting the battery in a waterproof box but mainly so i can mount the FF to it with an improvised transducer arm and mounting the box on top of my deck to make it easily removable and so i do not drill holes in the yak. also the box is large enough to hold things like cellphone, wallet, etc. i'm going to post pics of the finished product when all is said and done.
fortunatly, the FF came with the inline fuse and harness so i just need to figure out the wiring (with the help of your pics alan)
