When operators add modern trail accessories—such as auxiliary off-road lighting, recovery winches, upgraded stereo amplifiers, or electric cooling fans—the OEM stator quickly suffers from thermal saturation. Under continuous load at low trail RPMs, this shortfall creates excessive system voltage drops below 12.5V, resulting in dim instrumentation, weak ignition spark, sluggish starter recovery, and premature battery degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on upgrade for the carbureted \u003cstrong\u003e4ZD1\u003c\/strong\u003e 2.3L engine, this remanufactured 100-amp unit features heavy-gauge copper stator windings and a precision-balanced rotor to maximize current output without excessive rotational drag. Premium double-sealed bearings resist contamination from trail dust and mud, while a robust internal solid-state voltage regulator maintains a steady 13.5V to 14.5V charging threshold. The housing preserves OEM mounting lug dimensions, shaft depth, belt alignment, and terminal plug configurations, enabling factory integration without modifying brackets or wiring harnesses.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Remanufactured High Output 100 Amp Alternator (Part # 14859)\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;\"\u003e1986-1987 Isuzu Trooper\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;\"\u003e4ZD1 (2.3L SOHC) \/ UBS16\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;\"\u003e96 hp \/ 123 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;\"\u003e334-1913, AL421X, LR150-704, LR150-704H, 2912769300, 8943367300, 8944367300, 894449250, 14859N, 14859R\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\u003e1986 Isuzu Trooper 2.3L 4ZD1 (Base, DLX, LS)\u003c\/li\u003e\n  \u003cli\u003e1987 Isuzu Trooper 2.3L 4ZD1 (Base, DLX, LS)\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 UBS16 Trooper?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1986-1987 Isuzu Trooper equipped with the \u003cstrong\u003e4ZD1\u003c\/strong\u003e 2.3L four-cylinder engine, retaining the stock bracket geometry.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my main battery charge wire?\u003c\/h4\u003e\n\u003cp\u003eWhile the unit plugs into the factory harness, upgrading the primary B+ charge cable and chassis grounds to a heavier 4-gauge wire is recommended to deliver the full 100-amp capacity without thermal resistance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Isuzu Trail Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle extreme off-camber terrain and sustained electrical recovery demands, this charging upgrade delivers dependable overland durability for vintage Isuzu utility platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67901190603000,"sku":"DS-EYAP51I2H","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-isuzu-trooper-1986-1987-2-3l-1.jpg?v=1793334422","url":"https:\/\/performancechiptuning.com\/de\/products\/high-output-alternator-for-isuzu-trooper-1986-1987-2-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
