4. Fault component identified — alternator, starter, belt, or wiring
5. Replacement part sourced and confirmed compatible
6. Component replaced and belt tension set correctly
7. Charging system output verified post-installation

## FAQ

**Q: Can a bad alternator kill a new battery?**
A: Yes. An alternator that overcharges will damage a battery quickly. One that undercharges leaves the battery partially discharged on each cycle, shortening its life. Testing the alternator before replacing the battery again is always the correct sequence.

**Q: How long do alternators typically last?**
A: 120,000–200,000 km is typical, depending on the vehicle, load, and heat exposure. High-heat environments like Oman's climate can accelerate bearing and diode degradation.
