    Default Needing help with battery hookup.

    My Seven had a terminally dead battery. So I got a fresh one and suddenly remembered that I should have marked which wires go where. The way I've got it hooked now I only get a solenoid click but the starter doesn't rotate and the dash lights don't turn off.

    Anybody want to send a photo of their correct battery hookup?

    Are your cables color coded?
    Follow cable running to starter : +
    Cable running to ground/engine block: -
    Check fuses

    Not near my car right now to get you a photo sorry but you may also want to install a cut off switch to stop parasitic loss draining your battery.

    Perhaps it would help to know what kind of Seven, and a pic or two?

    On my '90 Caterham X-flow, the thick wires at the battery go to the Starter (+) and ground (-); there are also 2 smaller wires that come off the wiring loom near the battery and connect to the + side of the battery. I don't remember what they do.

    Thanks for all the help. I've got it right now.

    ( I had the headlights on but didn't notice because it was such a bright day.)
