    Question DC-DC Charger Earthing

    Greetings!

    With my limited knowledge in Electricity, Advice is needed for the earthing/ negative connection to my DC-DC Charger.
    2 Diagrams below indicate option 1 & option 2. Both of them work (I have tested it briefly) however I do not want to use my bakkie as an accidental fire lighter.
    Your feedback will be appreciated.
    Regards

    Both works the same so it does not matter.

    What sometimes does become a problem is the chassis conections. They corode and become troublesome.

    Rather just run seperate wires to both positive and negative-but purely from a long term reliability/fault finding.

    Remember to fuse both sides of the positive wires close to the batteries on each end.

    For these installations dedicated wiring for both + and - connections is best.

    Especially if your installation has distance between the components.(not all clustered together in engine bay)

    So your option 2 is the way to go
