Before proceeding with installation, carefully compare your existing magneto with the product image and description. Pay close attention to the number of stator coils and the configuration of the electrical connectors to ensure a correct match.

3. Pemasangan dan Persediaan

Installation of a scooter magneto requires mechanical aptitude and familiarity with scooter electrical systems. If you are not confident in your ability to perform this installation, it is highly recommended to seek assistance from a qualified scooter mechanic.

3.1 Langkah Keselamatan

• Always disconnect the scooter's battery before beginning any electrical work.
• Pakai peralatan pelindung diri yang sesuai, termasuk cermin mata keselamatan dan sarung tangan.
• Ensure the scooter is stable and secured on a stand to prevent accidental movement.
• Bekerja di kawasan pengudaraan yang baik.

3.2 Langkah Pemasangan Umum (Rujuk Manual Servis untuk Spesifikasi)

1. Locate and access the existing magneto assembly, typically behind the flywheel cover on the engine.
2. Carefully disconnect all electrical connectors leading to the old magneto. Note their positions for reinstallation.
3. Remove the flywheel using a specialized flywheel puller tool. Do not pry the flywheel off, as this can cause damage.
4. Unbolt and remove the old magneto stator assembly.
5. Install the new Generic Scooter Magneto, ensuring it seats correctly and all mounting bolts are tightened to the manufacturer's specified torque.
6. Reinstall the flywheel, ensuring the keyway aligns properly. Tighten the flywheel nut to specifications.
7. Reconnect all electrical connectors to the new magneto, matching them to their original positions.
8. Reassemble any covers or components removed during the process.
9. Sambung semula bateri.
10. Test the scooter's ignition and charging system.

4. Fungsi dan Operasi

The magneto is a passive component that generates electricity through electromagnetic induction as the engine's flywheel (which contains magnets) rotates around its coils. It serves two primary functions:

• Ignition Power: It produces the alternating current (AC) that is rectified and regulated to provide power for the ignition system, creating the spark needed to ignite the fuel-air mixture.
• Pengecasan Bateri: It generates AC power that is converted to direct current (DC) by the rectifier/regulator to recharge the scooter's battery and power other electrical accessories.

Once correctly installed, the magneto operates automatically as part of the engine's normal function. No user intervention is required for its operation.

5. Penyelenggaraan

The magneto itself is generally a sealed unit and requires minimal direct maintenance. However, regular inspection of related components can help ensure its longevity and proper function.

• Wiring and Connectors: Periodically inspect all wiring connected to the magneto for signs of wear, fraying, or corrosion. Ensure all connectors are clean, secure, and free from moisture.
• Flywheel Clearance: Ensure the flywheel rotates freely without making contact with the magneto stator coils. Any rubbing can indicate improper installation or a damaged component.
• Engine Environment: Keep the engine area clean and free from excessive dirt, oil, or debris, which can contribute to overheating or damage to electrical components.

If any issues are observed, consult a qualified mechanic for diagnosis and repair.

6. Penyelesaian masalah

If you experience issues with your scooter's electrical system after magneto installation, consider the following common problems and diagnostic steps. Always ensure safety precautions are followed before troubleshooting.

6.1 Common Symptoms of Magneto Issues

• No spark or weak spark at the spark plug.
• Battery not charging, or battery drains quickly.
• Engine misfires or runs poorly.
• Headlights or other electrical components dim or flicker.

6.2 Langkah Diagnostik Asas

1. Semak Sambungan: Ensure all electrical connectors from the magneto are securely attached and free from corrosion.
2. Pemeriksaan Bateri: Verify the scooter's battery is fully charged and in good condition. A weak battery can mask charging system issues.
3. Pemeriksaan fius: Inspect all relevant fuses for the charging and ignition systems.
4. Voltage Output Test (Advanced): Using a multimeter, test the AC voltage output from the magneto leads while the engine is cranking or running (if possible). Consult your scooter's service manual for expected voltage julat.
5. Resistance Test (Advanced): Measure the resistance (ohms) across the magneto coils. Compare readings to your scooter's service manual specifications. Deviations can indicate a faulty coil.

If these basic steps do not resolve the issue, professional diagnosis by a qualified mechanic is recommended.
