When subjected to modern electrical demands—such as auxiliary lighting, aftermarket audio, winch solenoids, or electric radiator fans—the OEM stator saturates rapidly. Thermal fatigue breaks down factory brush tracks, and stator coils suffer dielectric breakdown under sustained draw. This causes severe idle voltage drop, dimming headlamps, slow cranking cycles, and chronic undercharging that ruins lead-acid and AGM batteries prematurely.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered around heavy-gauge pure copper stator windings, this remanufactured unit pushes output to \u003cstrong\u003e100 amps\u003c\/strong\u003e at 12 volts, doubling OEM capacity without altering external packaging. It incorporates high-grade heat-dissipating solid-state internal regulation, a dynamically balanced rotor to prevent high-RPM harmonic shaft vibration, and double-sealed ball bearings rated for high radial belt loads. Retaining the OEM \u003cstrong\u003e4ZD1\u003c\/strong\u003e bracket geometry, single-groove V-belt pulley profile, and factory plug architecture, it drops directly into stock mounting positions with zero harness splicing required.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 High Output 100-Amp Remanufactured 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 Pickup\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) \/ KB Series\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, 14859\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 Pickup 2.3L L4 (Gas)\u003c\/li\u003e\n  \u003cli\u003e1987 Isuzu Pickup 2.3L L4 (Gas)\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 KB Pickup?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1986-1987 Isuzu Pickup equipped with the \u003cstrong\u003e4ZD1\u003c\/strong\u003e 2.3L carbureted engine using standard factory mounting ears.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging wiring?\u003c\/h4\u003e\n\u003cp\u003eWhile this unit functions with the original connector, upgrading your main B+ charging wire and engine block grounds to 4-gauge cable is recommended to realize the full 100-amp continuous throughput without line resistance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Isuzu Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eClassic utility pickups need uncompromising electrical resilience.
