    Earth Point

    I'm getting ready to earth the circuits in the car. The chassis is powder coated. Is it best to remove the powder coat so the bolt is touching bear metal or is it ok just to drill and tap into the chassis without removing the powder coat?

    Thanks
    Anthony

    If is a bolt clean the powdercoat away , if using a self tapping fixing leave on but put a washer each side of the electrical connector end .

    engine earths I welded a stud either side into the chassis. other earths, I used 5mm / 6mm studs threaded into the box section and locked off with nut and spring washers. you then have a good marshalling post for your earths.

    Thanks guys
    I was going to go down the threaded route into the box sections as well, just wanted to make sure this would provide an adequate earth with the powder coat left on.

    When I did my earth I put a long bolt right through the box section and welded the head underneath to the chassis leaving the threaded part sticking up free to use.
