4. Wiring and Connection
Proper wiring is crucial for the correct function of the voltmeter. Refer to the diagram below and the following instructions:
- Red Wire: Connect to +16-32VDC (positive power supply).
- Orange Wire: Connect to Red Backlight (+) (positive for backlight).
- Blue Wire: Connect to Ground (-) (negative power supply).
Note: If your product includes a volt gauge and hour meter, and there is no black wire, please refer to the specific wiring instructions provided with your product. Generally, black wires are not included in volt gauges and hour meters.

5. Operating Instructions
Once correctly installed and wired, the ELING Voltmeter operates automatically:
- Power On: After the voltmeter is powered on, it will immediately display the real-time voltage of the connected electrical system.
- Voltage Range: The gauge is designed to display voltage within the 16-32V range. If the voltage is too high or too low outside this range, it may not be displayed accurately or at all.
- Backlight: The red backlight will illuminate when the orange wire is connected to a positive power source, enhancing visibility in low-light conditions.

8. Troubleshooting
If you encounter issues with your voltmeter, consider the following common troubleshooting steps:
- No Display/No Power:
- Check all wiring connections (Red to positive, Blue to ground) for looseness or incorrect polarity.
- Verify the power source is providing voltage within the 16-32V operating range.
- Check for blown fuses in the power circuit.
- Inaccurate Readings:
- Ensure the gauge is receiving stable power and ground connections.
- Confirm the voltage of your system with a separate, calibrated multimeter to compare readings.
- Backlight Not Working:
- Check the connection of the Orange wire to the positive power source.
- Ensure the power source for the backlight is active.
