Referring to my earlier thread 'Electrolytic & Galvanic avtivity' on my newly aquired boat, I have these two devices:
The red wire goes to the aternator, the black goes around the back of the engine somewhere, and the green is obviously the earth. Can anyone tell what they are or what they do. Could they some be sort of galvanic isolator or are they some sort of suppressor??? The previous owner did not know what they are.
My engine is a Volvo 2002
