2. Sikkerhedsoplysninger
Always prioritize safety during installation and operation. Failure to follow these guidelines may result in injury or damage to the product or vehicle.
- Ensure the vehicle's engine is off and cooled down before beginning any installation.
- Disconnect the vehicle's battery to prevent electrical shorts during installation, especially if connecting lighting.
- Brug passende personlige værnemidler, herunder sikkerhedsbriller og handsker.
- Route all lines and wiring away from hot engine components, moving parts, and sharp edges.
- Secure all connections to prevent leaks or disconnections during vehicle operation.
- Hvis du er usikker på et trin, skal du kontakte en kvalificeret biltekniker.

4. Opsætning og installation
The Auto Meter 4301 is a mechanical gauge, meaning it does not require an electrical system for its primary operation, making it compatible with a wide range of vehicles. Electrical connections are only required for the optional dial illumination.
4.1. Montering af måleren
- Select a suitable location for the gauge within the vehicle's cabin that allows for clear visibility and does not obstruct driving controls or airbags.
- Using the provided mounting hardware, secure the gauge firmly in place. Ensure the mounting surface is stable and can support the gauge's weight and vibrations.
4.2. Connecting the Vacuum/Boost Line
- Identify a reliable vacuum/boost source on your engine. This is typically a manifold vacuum port or a dedicated boost reference port.
- Using the T-fitting, splice into an existing vacuum line or connect directly to an available port using the vacuum fitting.
- Connect one end of the 1/8" nylon line to the vacuum/boost source using the appropriate compression fittings. Ensure a tight, leak-free connection.
- Carefully route the nylon line from the engine bay into the vehicle's cabin to the back of the gauge. Avoid sharp bends that could kink the line.
- Connect the other end of the nylon line to the inlet port on the back of the Auto Meter 4301 gauge using the remaining compression fittings. Tighten securely to prevent leaks.
4.3. Connecting the Illumination (Optional)
For dial illumination, connect the included bulb and socket assembly:
- Insert the bulb into the socket assembly.
- Choose either the red or green bulb cover and place it over the bulb for desired illumination color.
- Insert the bulb and socket assembly into the designated port on the back of the gauge.
- Connect the two wires from the socket assembly to a switched 12V power source (e.g., vehicle's dash lighting circuit) and a good chassis ground. This will allow the gauge to illuminate with your vehicle's lights.
5. Betjeningsvejledning
Once properly installed, the Auto Meter 4301 gauge operates automatically with the engine. The gauge displays both vacuum and boost pressure on a single dial.
- Vacuum Readings: When the engine is running at idle or under light load, the gauge pointer will move into the 'VAC' (Vacuum) section, typically measured in In.Hg (Inches of Mercury). Higher vacuum readings (closer to 30 In.Hg) generally indicate efficient engine operation.
- Boost Readings: When the engine is under load and the turbocharger/supercharger is active, the gauge pointer will move into the 'PRESS' (Pressure) or 'BOOST' section, measured in PSI (Pounds per Square Inch). The gauge can read up to 20 PSI of boost.
- Belysning: If the illumination was connected, the gauge dial will light up when the vehicle's lights are activated, providing visibility in low-light conditions.
6. Vedligeholdelse
The Auto Meter 4301 mechanical gauge requires minimal maintenance to ensure continued accuracy and longevity.
- Regelmæssig inspektion: Periodically inspect the nylon line for any signs of kinking, chafing, or damage. Ensure all compression fittings remain tight and free of leaks.
- Rensning: Rengør målerens overflade med en blød,amp cloth. Avoid abrasive cleaners or solvents that could damage the lens or markings.
- Udskiftning af pære: If the illumination bulb burns out, it can be replaced by carefully removing the bulb and socket assembly from the back of the gauge and inserting a new compatible incandescent bulb.
7. Fejlfinding
If you encounter issues with your Auto Meter 4301 gauge, refer to the following troubleshooting guide:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Gauge reads zero or stuck | Kinked or blocked nylon line; disconnected line; faulty vacuum/boost source. | Inspect the entire length of the nylon line for kinks or obstructions. Verify all connections are secure. Check the engine's vacuum/boost source. |
| Unøjagtige aflæsninger | Line leaks; incorrect vacuum/boost source; gauge malfunction. | Check all line connections for leaks. Ensure the gauge is connected to a proper, stable vacuum/boost source. If issues persist, the gauge may require professional inspection. |
| Ingen belysning | Burnt out bulb; loose electrical connection; no power to illumination circuit. | Check the bulb and replace if necessary. Verify electrical connections for the bulb and socket assembly are secure and receiving 12V power and ground. |
