I want to add some lights around the inside of my 14 foot aluminum boat so that I can see what I'm doing at night. I specifically want to light up the floor area of the boat (so I can find my spilled tackle).
Can the aluminum structure of the boat be used as a ground, or must I run separate ground wires for each light? I ask this because the original wiring does not use the aluminum as a ground. I am thinking that there must be a reson for this.
