Product Description:

 
Auto alternators
OE number: YLE500390 LR008860 YLE500190
Applicable vehicle type: For Volvo
 
 
 
As a core power supply component, automotive generators, when faulty, will directly cause vehicle electrical equipment to malfunction, the battery to discharge, and even engine stalling. Their faults are mostly concentrated in abnormal power generation, abnormal noise, and no power generation.
 
Fault: Alternato not generating electricity

Maintenance Steps

1. Preliminary Troubleshooting:

• Check the Belt: Observe whether the belt is broken or cracked. Press the belt with your finger; the deflection should be ≤15mm (if too loose, adjust the tension pulley);
• Check the Wiring: Confirm that the connections between the generator output terminal (B+), excitation terminal (F), the battery, and the wiring harness are secure, and check for oxidation or rust (sandpaper can be used to polish the terminals).

2. Component Testing and Repair:

• Brushes and Brush Holder: Open the rear cover and remove the brush holder. If the brushes are worn excessively, replace them with brushes of the same model directly; if the brushes are jammed, clean the impurities in the brush holder and apply a small amount of lubricating grease;
• Voltage Regulator: Measure the input/output voltage of the regulator with a multimeter. If there is no voltage output, replace the regulator directly (for some vehicle models, the regulator is integrated with the generator and needs to be replaced as a whole);
• Stator/Rotor Windings: Detect with the multimeter's 'Resistance Range':
• Stator Windings: Measure the resistance between the three-phase windings, which should be uniform (about 0.2-0.5Ω). If the resistance of a certain phase is infinite (open circuit) or close to 0Ω (short circuit), replace the stator assembly;
• Rotor Windings: Measure the resistance between the slip rings (about 3-5Ω). If the resistance is infinite (open circuit) or too small (short circuit), replace the rotor assembly;
• Bearings: If there is abnormal noise or play when rotating the rotor shaft, disassemble and replace the same model sealed bearing (note to apply high-temperature resistant lubricating grease).
