5.3 Інструкцыі па падключэнні
The tachometer typically has three wires for connection:
- Чырвоны провад: Connect to a switched 12V DC power source (e.g., ignition switch ACC).
- Чорны провад: Connect to a reliable vehicle ground point.
- 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. Інструкцыя па эксплуатацыі
Once properly installed and wired, the Docooler Digital Tachometer K975 operates automatically when the vehicle's ignition is turned on.
- Уключэнне: When the ignition is turned to the ACC or ON position, the tachometer will power on, and the blue digital LED display will illuminate.
- Дысплей абаротаў у хвіліну: The display will show the current engine RPM in numerical format.
- Папярэджанне: 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. Тэхнічнае абслугоўванне
The Docooler Digital Tachometer K975 is designed for durability and requires minimal maintenance.
- Уборка: Выкарыстоўвайце мяккую сухую тканіну для чысткі дысплея іasing. Avoid abrasive cleaners or solvents that could damage the plastic or screen.

- Ахова навакольнага асяроддзя: While designed for automotive use, avoid exposing the gauge to extreme moisture or direct, prolonged sunlight when possible to extend its lifespan.
8. Выпраўленне непаладак
If you encounter issues with your tachometer, refer to the following common problems and solutions:
| праблема | Магчымая прычына | Рашэнне |
|---|---|---|
| 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. | Ensure signal wire is routed away from high-voltage 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. |
