    Hello.
    1983 308 GTS QV.
    Hidden under my battery mount I found the original, I think, negative battery cable/chassis ground which was at some point chopped off and left for dead.
    Image Unavailable, Please Login

    The other 1/2 of the connector I assume attaches to a grounding strap and to the frame. Does anyone have a photo showing it in place? I just have an aftermarket undersized cable with an eye at the end attached to a bolt drilled into the frame without any attention to detail or respect.

    Thank you.

    Do a search using "Anderson PP120" for prior threads that might have some photos (that connector is an Anderson PP120 Powerpole connector).

    While it is a high quality connector, its location is not as easy to access. I removed mine all in one piece, attached a ground cable switch ( a red 90 degree twist ground isolator switch whose key comes out ). I can disable the battery with one twist now.

    Why in this world's hell would anyone think it would be best for the car to cut that thing off?

    Not easy to access? Unless it was bolted to the hood I cannot imagine it being easier to get to.

    Probably, the other half broke or one of the contacts burned/melted.

    I think the OEM connector is great - I disconnect/connect mine on a regular basis - don't even need to look/just by feel.

    It's great ... but with the removable key of the after market twist switch, I can take the key with me and it becomes an antitheft device.

    I have installed a battery tender with a plug poking out just behind the grill, I just park it and plug it in, But before that it was disconnect with that cable.

    Thank you for the great info. I think I will return my ground to OEM style. The current "repair" is substandard.This particular car has seen a lot of thoughtless modifications in the past 40+ years. And a few decent ones too.
