[QUOTE=C_Spray;3075618]I think you mean yellow for 12VDC negative. That eliminates the black/black confusion.
You are correct. Thanks for the correction.
I edited my post for saftey reasons.
Not sure where I came up with the red wire. Brain fart
Some people are like Slinkies - Not really good for anything, but they
bring a smile to your face when pushed down the stairs.
All the AC systems and bonding systems I've worked on over the years are done this way... It serves multiple purposes a few examples are; 1. alternate ground, 2. galvanic corrosion due to reversed polarity. 3. old wires from old docks laying in the water causing stray currents .
Green is the universal ABYC wire color for a bonding system.
I am by no means an electrician, and maybe I'm wrong but doesn't connecting the two systems in this manner introduce stray current to the prop shaft in turn causing issues?
Can you explain this? I have been around batteries that are wet from fresh water with no effect, but tried jumping a jetski in the ocean and had the holy chit shocked out of me...Electrocution is less likely in saltwater, but the current field can be enough to paralyze muscles and cause a swimmer to drown.
please read the fine print
Keep in mind, pure water is an insulator, it's the elements that exist in water that are conductive. Salt Water, lake water or river water it doesn't matter. If there is iron there is a pathway for current. It only takes 4 mili-amps to kill.
use a galvonic isolator!!!!
Someone life is not worth leaving it out.
I would install the isolators for corrosion protection. But again consult the manufacturer for correct installation. You may need two since AC current flows in both directions. Depends on charger or inverter systems install.
Thanks for better understanding
Now I'm really confused. Is the galvanic isolator's purpose to protect from corrosion that might be caused from other boats or shore power cords hanging in the water at a marina or to protect from corosion from your own boat "if that is even possible"? Will hooking up the green AC ground to the DC negative on the boat provide an opportunity to introduce corrosion to your boat? This is turning out to be more complicated than I thought.
