Polish oxidized terminals with sandpaper and apply a small amount of conductive paste.Grounding inspection: Clean rust and oil stains at the grounding position between alternator and engine to ensure good conduction.Voltage measurement: Start the engine and keep speed at 1500-2000rpm. Measure voltage of B+ terminal with multimeter. Normal range is 13.5-14.5V. Exceeding the range is mostly caused by regulator failure.Common Fault Diagnosis & SolutionsCharging indicator light stays on after engine startsReason: Alternator no power generation, drive belt slipping, loose / oxidized wiringSolution: Check belt deflection; fasten wiring terminals and clean grounding position; measure B+ terminal voltage, repair alternator or regulator if no voltage output.Charging indicator light does not light up at ignition switch ON gearReason: Damaged indicator light, loose connection of L terminalSolution: Replace dashboard charging indicator light; check and fasten wiring of L terminal.B+ terminal voltage higher than 14.5VReason: Regulator failureSolution: Replace with the same model regulator compatible with original vehicle.B+ terminal voltage lower than 13.5VReason: Belt slipping, loose wiring of F terminal, rectifier failureSolution: Adjust belt tightness; check connection reliability of F terminal; professional inspection is required if rectifier is damaged.Abnormal noise during alternator operationReason: Bearing wear, friction between rotor and stator, belt abnormal noiseSolution: Replace worn bearing; check gap between rotor and stator to avoid friction; adjust belt tension to eliminate belt noise.Safety WarningBefore wiring and maintenance, must disconnect the battery negative pole to prevent spark caused by short circuit, avoiding electric shock or fire risk.Do not touch wiring terminals and rotating parts while the alternator is working to prevent electric shock and injury.When replacing accessories such as regulator and rectifier, please select models compatible with original vehicle. Mixing different specification parts is prohibited.If the alternator emits smoke or burning smell, turn off the engine and power supply immediately. Do not use it forcibly until troubleshooting after cooling down.
