5.3 Istruzioni per il cablaggio
The tachometer typically has three wires for connection:
- Filo rosso: Connect to a switched 12V DC power source (e.g., ignition switch ACC).
- Filo nero: Collegarsi a un punto di messa a terra affidabile del veicolo.
- Green/Yellow/White Wire (Signal): Connect to the engine's RPM signal wire. This is typically found at the ignition coil negative terminal, ECU tachometer output, or specific engine sensor. Consult your vehicle's service manual for the exact location of the RPM signal wire.
Ensure all connections are soldered or crimped securely and insulated with electrical tape or heat shrink tubing.
6. Istruzioni per l'uso
Once properly installed and wired, the Docooler Digital Tachometer K975 operates automatically when the vehicle's ignition is turned on.
- Accensione: When the ignition is turned to the ACC or ON position, the tachometer will power on, and the blue digital LED display will illuminate.
- Visualizzazione del numero di giri: The display will show the current engine RPM in numerical format.
- Spia luminosa: The integrated warning light will activate when the engine RPM reaches or exceeds 5000 RPM. This serves as a visual alert for high engine speeds.
7. Manutenzione
The Docooler Digital Tachometer K975 is designed for durability and requires minimal maintenance.

- Protezione ambientale: While designed for automotive use, avoid exposing the gauge to extreme moisture or direct, prolonged sunlight when possible to extend its lifespan.
8. Risoluzione Dei Problemi
If you encounter issues with your tachometer, refer to the following common problems and solutions:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Tachometer does not power on. | No power to the red wire; poor ground connection. | Check 12V power supply and ground connections. Ensure ignition is on. |
| Display shows "0" or incorrect RPM. | Incorrect or loose signal wire connection; incompatible signal type. | Verify the signal wire is correctly connected to the RPM source. Ensure the signal source is active. Some vehicles may require a tach adapter. |
| RPM reading is sluggish or jumps erratically. | Interference in the signal wire; poor signal quality; loose connections. | Assicurarsi che il cavo del segnale sia instradato lontano da fonti ad alto volumetage cables. Check all wiring connections for tightness and proper insulation. |
| Warning light does not activate at 5000 RPM. | Faulty internal component; incorrect RPM signal. | Verify RPM reading accuracy. If RPM is correct and light still fails, the unit may be faulty. |
