• Can be calibrated to work with 4, 6, and 8 cylinder engines and outboards.
• Features a chrome bezel and black dial with Domelux lens for clear visibility.
• Offers a 0 to 8000 RPM scale in 100 RPM increments.
• Includes two installation options: using the provided hardware or an inductive pickup.

2. Safety Information

Always prioritize safety during installation and operation. Disconnect the vehicle's battery before beginning any electrical work to prevent short circuits and potential injury. Ensure all wiring connections are secure, properly insulated, and routed away from moving parts or heat sources. If you are uncertain about any installation steps, consult a qualified automotive technician.

3. Package Contents

The Equus 7068 Tachometer package typically includes:

• One (1) Equus 7068 Tachometer unit
• Necessary installation hardware
• Inductive pickup for ignition system connection

4. Setup & Installation

The Equus 7068 Tachometer is compatible with a wide range of ignition systems, including conventional, electronic, and distributorless types. It can be calibrated for 4, 6, and 8-cylinder engines, as well as outboard motors. Two primary installation methods are provided: using the included hardware for direct mounting, or utilizing the inductive pickup for specific ignition system connections.

Wiring:

For detailed wiring instructions, refer to the wiring diagram provided with your specific product packaging. Generally, the tachometer requires connections for power (12V), ground, and the ignition signal. Ensure all connections are tight and insulated to prevent electrical issues.

Calibration:

To calibrate the tachometer for your engine, locate the calibration switches or settings, typically found on the back of the unit. Adjust these settings according to your engine's cylinder count (4, 6, or 8 cylinders) or for outboard use. Incorrect calibration will result in inaccurate RPM readings.

This image shows the Equus 7068 Tachometer, featuring a black dial with white numbering and a chrome bezel. The gauge displays RPM readings from 0 to 8000.

5. Operating Instructions

Once installed and calibrated, the tachometer will display the engine's RPM on its black dial. The scale ranges from 0 to 8000 RPM, with increments of 100 RPM. The needle will move in real-time to indicate the current engine speed. Monitor your engine's RPM to ensure optimal performance and prevent over-revving.

6. Maintenance

The Equus 7068 Tachometer is built with non-corrosive hardware and features a gasket-sealed lens and bezel to resist fogging and withstand severe conditions. To maintain its appearance and functionality, periodically wipe the lens with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the lens or finish. Ensure the bezel and lens remain sealed to prevent moisture ingress.

7. Troubleshooting

Tachometer not reading or erratic readings:

• Verify all wiring connections are secure and correctly made (power, ground, ignition signal).
• Check the calibration settings to ensure they match your engine's cylinder count.
• Ensure the inductive pickup (if used) is correctly positioned and making good contact with the ignition wire.
• Inspect for any loose connections or damaged wires.
• If the needle jumps erratically, this could indicate an issue with the ignition signal or a faulty connection. Re-check the signal wire connection to the ignition system.

No power to the tachometer:

• Check the fuse in the power circuit.
• Verify the 12V power connection and ground connection are secure.
