Ground Straps

Engine ground straps are essential, as they provide the ground connection for the starter motor, which typically draws 200-300 amperes. Should a ground strap be badly frayed, corroded, or otherwise unable to support this current, the starter motor will not be able to function efficiently. In extreme cases, the current will be carried by whatever else is providing a current path between the body of the car and the engine - usually the choke cable, which will become red hot, and may even burn through.
