Between heavy glow plug draw cycles, aftermarket winches, plows, and high-idle demands, the factory diodes quickly encounter severe heat soak. This thermal saturation leads to excessive voltage drops below 13.2V, which starves the high-voltage Injector Drive Module (IDM) and causes sluggish HEUI injector operation, hard starts, and premature battery degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for commercial-grade durability, this 250-amp direct replacement is manufactured in the USA using heavy-gauge copper windings and high-efficiency 12-diode heavy-duty rectifiers. The internal housing increases cooling airflow around the stator to counteract thermal fade during extended idling. By sustaining 14.4 volts under peak continuous electrical load, this unit protects delicate engine control electronics and ensures dependable starting power.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 High Output 250-Amp Alternator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2002-2003 Ford Excursion, F-250, F-350, F-450, F-550\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e7.3L Power Stroke \/ PN96 \u0026amp; U137\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e250 hp \/ 505 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2C3U10300BC, 8316, 8316n, AL7610X, 2C3Z10300BB, 8316-250A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2003 Ford Excursion 7.3L\u003c\/li\u003e\n  \u003cli\u003e2002-2003 Ford F-250 7.3L\u003c\/li\u003e\n  \u003cli\u003e2002-2003 Ford F-350 7.3L\u003c\/li\u003e\n  \u003cli\u003e2002-2003 Ford F-450 7.3L\u003c\/li\u003e\n  \u003cli\u003e2002-2003 Ford F-550 7.3L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the PN96 \/ U137 Excursion, F-250, F-350, F-450, F-550?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2003 Ford Excursion, F-250, F-350, F-450, F-550 equipped with the \u003cstrong\u003e7.3L Power Stroke\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eShould I upgrade my battery charge wire when installing this 250A unit?\u003c\/h4\u003e\n\u003cp\u003eYes, running an upgraded 4-gauge or 1\/0-gauge fused charge lead directly to the positive battery terminal is strongly recommended to safely handle the 250-amp peak current output without bottlenecking.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle grueling commercial fleet use and extreme towing cycles, this alternator delivers uninterrupted charging stability whether hauling heavy goosenecks across highway grades or running high-draw recovery gear on remote job sites.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67566279327992,"sku":"DS-EWZ0CR89Y","price":236.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-ford-excursion-f-250-f-350-f-450-f-550-2002-2003-7-3l-1.jpg?v=1791085634","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-ford-excursion-f-250-f-350-f-450-f-550-2002-2003-7-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
