Quality-Built 15919N New Alternator Internal Regulator - 70A 12V

The Quality-Built 15919N is a 100% brand-new alternator engineered to meet or exceed original equipment (OE) specifications for output, fit, and durability. Manufactured as a direct replacement for the original Nippondenso unit (OE Part Number: 102211-5020), this alternator delivers dependable 12-volt charging system performance right out of the box.

Unlike remanufactured units, the 15919N is built entirely from new components — from the rotor and stator to the bearings, rectifier, voltage regulator, and housing — ensuring consistent performance and long service life without the uncertainty of recycled parts.

Key Features:

• 100% New Construction: Every component is new, including internal fasteners and bolts, for unsurpassed out-of-box reliability
• 70-Amp Output: Delivers 70 amps at 12 volts to reliably power all vehicle electrical demands
• 5-Groove Serpentine Pulley: Included pulley matches OE belt configuration for a direct, hassle-free installation
• Internal Fan & Internal Regulator: Compact OE-style design with clockwise rotation and internal voltage regulation
• Premium Bearings: High-quality steel bearings packed with extreme-temperature lubricant and double groove seals to prevent grease leakage and ensure quiet, long-lasting operation
• High-Amperage Press-Fit Diodes: Greater surface area for faster heat dissipation from the rectifier, improving durability under thermal cycling
• OE-Spec Copper Windings: Rotors and stators wound with high-temp polymer-coated copper wire and checked for correct air-gap to maximize output
• ISO/TS 16949 Certified Manufacturing: Produced in certified facilities under stringent engineering and quality control processes
• 100% End-of-Line Tested: Every unit is fully tested before shipment to verify voltage output and amperage across the full operating range

The Quality-Built 15919N replaces OE Nippondenso part number 102211-5020 and is a straightforward bolt-on replacement. With a clockwise rotation, internal regulator, and included serpentine pulley, this alternator is ready to install and built to last.
