Forklift Alternator A2TN0399 12V 65A for 4D55 L300 Engine
The alternator is the primary electrical power source for the forklift, converting mechanical energy from the engine crankshaft pulley into electrical energy to charge the battery and power all electrical systems during operation. Part numbers A2TN0399, MD304129, and LRA01556 identify this 12-volt, 65-amp OEM-spec alternator for the Mitsubishi 4D55 diesel engine — a powerplant used in Mitsubishi L300 light trucks and select Mitsubishi-powered forklifts. A failing alternator causes battery discharge, dimming dashboard and work lights, erratic electrical system behavior, and eventual complete battery drain that leaves the forklift stranded.
The alternator features a three-phase stator winding with a built-in voltage regulator and rectifier assembly that maintains a stable 14.2-14.8V charging output across the full engine speed range. The rotor is supported by sealed ball bearings for extended service life in dusty and high-vibration industrial environments. The 65-amp output capacity provides sufficient electrical power for the engine ECU, fuel solenoid, instrumentation, lighting, and battery charging. Factory testing includes output current verification at multiple RPM points and voltage regulation stability testing before shipment.
This alternator is a direct bolt-on replacement for the Mitsubishi 4D55 2.5L diesel engine found in Mitsubishi L300 vans and trucks, as well as select Mitsubishi forklift applications using the 4D55 power platform. The multiple cross-reference part numbers — A2TN0399, MD304129, LRA01556 — ensure correct sourcing across Mitsubishi OEM, aftermarket, and Lucas/TRW parts catalogs. Installation requires belt tension adjustment and verification of the charging voltage after installation — always check the battery condition and alternator wiring connections during replacement.
