When you press the starter button, the **starter relay** closes the high-current circuit between the battery and the starter motor, which turns the crank through gears and the [starter clutch](https://motorsikletparcasi.com/en/glossary/starter-clutch).

## Likely cause by symptom

- **Just a "click":** weak [battery](https://motorsikletparcasi.com/en/glossary/battery), corroded terminals or starter relay
- **Slow cranking:** weak battery, worn starter brushes
- **Starter spins but the engine does not turn:** starter clutch or gear fault

Operate the starter in short bursts of a few seconds; holding it for long overheats the motor.
