{"product_id":"0009062904","title":"Mercedes Sprinter Alternator 280A – Valeo | VS30 2.1L OM651 Diesel | #0009062904 (2020–2025)","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA failing alternator on a VS30 Sprinter will drain the battery under load, dim the lights at idle, and eventually leave you with a dead van — often without warning until the battery voltage drops below the point where the ECU can maintain normal operation. This is the Valeo 280-amp alternator for VS30 Sprinters equipped with the 2.1L OM651 diesel engine, a direct replacement that restores full charging output and stable electrical system performance across all operating conditions.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat This Part Does\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe alternator is driven by the serpentine belt and converts mechanical energy from the engine into the electrical current that charges the battery and powers every system on the van — from the ECU and fuel injectors to the lights, HVAC blower, and any upfitted electrical equipment. At 280 amps this unit is rated for the substantial electrical demands of the VS30 platform, with headroom for vans equipped with upfitted inverters, refrigeration units, lighting arrays, and other aftermarket electrical loads common in commercial and fleet applications. When the alternator's diode pack, voltage regulator, brushes, or bearings fail, charging voltage drops or becomes erratic — causing battery drain, voltage-sensitive fault codes from the ECU, and eventually a no-start.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCommon Symptoms of a Failing Alternator\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBattery warning light or low voltage warning in the instrument cluster\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHeadlights that dim at idle and brighten under acceleration\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBattery that drains overnight or fails to hold a charge despite being healthy\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eVoltage-related fault codes or electrical system warnings after extended idling\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWhining or grinding from the alternator pulley area under load\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRepeated battery failures that return after replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhen to Replace\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eReplace when charging voltage is confirmed below specification under load and the alternator is diagnosed as the fault source after ruling out the serpentine belt, battery condition, and charging circuit wiring.
