## The "Click of Death" (Battery Failure)
It's the #1 breakdown cause, especially in winter or after a long period of inactivity. You turn the key, dashboard lights dim, and nothing happens.
### Symptoms: Battery or Alternator?
- **Dead Battery**: If you jump-start it and the car runs fine afterwards, it was likely just drained (forgotten lights?).
- **Faulty Alternator**: If the car stalls shortly after starting, or the battery light stays on while driving, the alternator is not charging anymore.
### Jump Starting with Cables (Warning!)
Connecting two cars with alligator clips seems simple, but modern electronics are fragile! A power surge can fry your ECU.
- Respect the order: Red (+), then Black (-).
- Do NOT touch the bodywork.
