This used BMW Alternator / Starter Cable, OEM part number 1439743, is a genuine factory component removed from a donor vehicle. Also known as the alternator cable or starter cable, it carries current between the alternator and starter on numerous BMW six-cylinder engines. A common failure is a frayed or corroded cable, which can cause intermittent no-starts or charging faults.
