Setup & Installation
Follow these steps for proper installation and wiring of the tachometer sender adapter.
1. Wiring Connection
Connect the wiring harness according to the diagram below:
- Red Wire: Connect to +9-32VDC power supply.
- White Wire: Connect to RPM Signal Input (from engine/alternator).
- Yellow Wire: Connect to RPM Signal Output (to tachometer).
- Black Wire: Connect to Ground (-).

2. DIP Switch Configuration
The adapter features two banks of 8 DIP switches (labeled A and B) to select the appropriate channel for your RPM signal input. Only one channel (CH1-CH8) should be selected at a time. To select a channel, set the corresponding DIP switch in both bank A and bank B to the 'ON' position, and ensure all other switches are 'OFF'.
For example, to select Channel 1 (CH1), set DIP switch A1 to 'ON' and DIP switch B1 to 'ON'. All other DIP switches (A2-A8, B2-B8) must be 'OFF'.
Refer to the table below for channel descriptions (for reference only):
| Channel | Description (Frequency & Amplitude) |
|---|---|
| CH1 | Suitable for Frequency (F) <10KHz and Signal Amplitude >4V |
| CH2 | Suitable for Frequency (F) <10KHz and Signal Amplitude >2V |
| CH3 | Suitable for Frequency (F) <10KHz and Signal Amplitude >1V |
| CH4 | Suitable for Frequency (F) <10KHz and Signal Amplitude >7V |
| CH5 | Suitable for Frequency (F) <10KHz and Signal Amplitude >6V |
| CH6 | Suitable for Frequency (F) <10KHz and Signal Amplitude >5V |
| CH7 | Suitable for Frequency (F) <10KHz and Signal Amplitude >4V |
| CH8 | Suitable for Frequency (F) <1KHz and Signal Amplitude >6V |
Operation
Once the adapter is correctly wired and the appropriate DIP switch channel is selected:
- Ensure all connections are secure and the power supply is within the 9-32VDC range.
- Start your engine.
- Observe the LED indicator on the adapter. If there is an RPM signal output, the LED will flicker, indicating proper operation.
- Your tachometer should now display the engine's RPM.
Maintenance
The ELING Tachometer Sender Adapter is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:
- Periodically check all wiring connections for tightness and signs of wear or corrosion.
- Keep the adapter clean and free from excessive dirt or debris. While it is IP67 waterproof, extreme conditions should be avoided.
- Do not attempt to open the casing of the adapter, as this may void any potential warranty and could damage the internal components.
Troubleshooting
If you encounter issues with your tachometer sender adapter, refer to the following common problems and solutions:
- No RPM Reading / Tachometer Not Working:
- Verify all wiring connections (Red to power, Black to ground, White to signal input, Yellow to signal output) are correct and secure.
- Ensure the power supply (9-32VDC) is active and within the specified range.
- Check the DIP switch settings. Only one channel should be 'ON' (e.g., A1 and B1 for CH1), and all others 'OFF'. Incorrect settings can prevent signal output.
- Confirm that the selected DIP switch channel (CH1-CH8) is appropriate for your engine's RPM signal frequency and amplitude.
- Check if the LED indicator on the adapter is flickering when the engine is running. If not, there might be an issue with the input signal or the adapter itself.
- Inaccurate RPM Reading:
- Re-evaluate your DIP switch channel selection. A different channel might be more suitable for your specific engine's signal characteristics.
- Ensure the input signal from the engine/alternator is clean and stable. Interference can affect accuracy.

User Tips
- Double-Check Connections: A common issue is incorrect or loose wiring. Always ensure the Red, White, Yellow, and Black wires are connected to their correct terminals and are securely fastened.
- DIP Switch Precision: When setting the DIP switches, use a small tool (like a pen tip or small screwdriver) to ensure each switch is fully 'ON' or 'OFF'. Only one channel should be active at a time.
- Test Channels: If you're unsure which channel is best for your engine, you may need to test a few different settings (e.g., CH1, CH2, CH3) to find the one that provides the most stable and accurate RPM reading for your specific application.
