Installation Guidelines

1. Preparation: Disconnect the battery and remove the old alternator following manufacturer safety procedures.
2. Mounting: Align the new alternator with the engine block using the standard mounting bolts. Tighten to the specified torque settings.
3. Electrical Connections: Connect the high‑current output leads to the battery and starter system, ensuring correct polarity. Attach the regulator wiring as per the schematic.
4. Testing: Start the engine and verify that the alternator charges the battery correctly. Check voltage output (should be ~28 V) and ensure no abnormal heat buildup.

Maintenance & Troubleshooting

• Regular Inspection: Periodically check for loose connections, worn belts, and signs of corrosion on the housing.
• Cooling System Check: Ensure that airflow around the fins is unobstructed; clean any accumulated dust or debris.
• Voltage Regulation: If voltage dips below 28 V under load, inspect the regulator circuit and replace if necessary.
• Belt Tension: Maintain proper belt tension to prevent slippage, which can reduce alternator output.
