Disconnect Battery Before Work
Always disconnect the negative terminal of the battery before removing or installing the alternator.
Prevents short circuits and protects sensitive electronics.
Check Drive Belt Tension
Use correct tension: typically allows 8–12 mm deflection at midpoint under 10kg force.
Too loose → slippage, reduced output
Too tight → bearing wear, shaft deformation
Inspect Drive Belt Condition
Replace cracked, glazed, or frayed belts.
Match belt type: 6PK or 8PK multi-ribbed V-belt.
Ensure Proper Grounding
Clean contact points between alternator and engine block.
Apply anti-corrosion grease to prevent resistance buildup.
Verify Electrical Connections
Output terminal (B+) is securely tightened
Regulator connector (D+, IG) is clean and undamaged
Check that:
Corrosion or loose wires cause charging failure.
Avoid Oil and Water Exposure
Keep alternator dry and free from oil leaks.
Contamination can damage insulation, seals, and bearings.
Do Not Run Without Load
Never operate the alternator without being connected to the battery or load.
Risk of voltage surge and regulator damage.
Test After Installation
Start engine and measure output voltage at idle (~27.5–28.5V).
Increase RPM to 1,500 and confirm stable reading.
Use Correct Tools
Avoid impact tools that may damage internal components.
Use torque wrench if specified by manufacturer.
Storage Advice
Store upright in dry indoor environment.
Keep terminals covered to prevent oxidation.
