Very Basic DC Wiring Question
As the new owner of a 30 year old Vagabond 17, I decided to try getting the long dormant electrical system to work. After looking through the masses of wiring (all black), corroded connectors, and occasional lamp wire connections, I figured a complete rewire is necessary and not too difficult on that size boat. All that is involved is a marine battery, 6 fuse panel, nav lights, bilge pumps, etc. BTW - I use an electric trolling motor for alt propulsion.
My question (finally) is: considering the simplicity of the system and my extremely limited understanding of electricity, is there any need for a "ground" or will the battery's negative terminal be all I need? The negative terminal is connected to the negative bus on the panel so all electrical items will be hooked directed to battery negative.
My brother is telling me I need to have a green "ground" wire connected to the keel or something similar. Thoughts from all of you much more experienced in this? Thanks in advance...
