This is a used OEM BMW Alternator / Generator Cable, part number 7934424, removed from a donor vehicle. It connects the alternator to the battery and electrical system, supplying charging current. A failing cable can cause a no-start condition, dimming lights, or a battery warning light on the dash. This cable was originally fitted to 4.4L N63 V8 turbocharged engines in models like the 750i xDrive and M850i xDrive.
