Introduction to Tachometers and Distributors

A tachometer measures the rotation speed of the engines crankshaft, displaying it in revolutions per minute (RPM). The distributor, on the other hand, is a device that routes high voltage from the ignition coil to the spark plugs in the correct firing order.

Understanding the Basics

What is a Tachometer?

A tachometer is an instrument that measures the rotational speed of an engine’s crankshaft. It provides valuable information about the engine’s performance, helping to ensure the engine is running efficiently and within safe limits. Learn more about tachometers.

What is a Distributor?

A distributor is an electrical device in internal combustion engines that routes secondary, or high-voltage, current from the ignition coil to the spark plugs in the correct firing order. Read more about distributors.

Tools and Materials Needed

Before you start, gather the following tools and materials:

  • Tachometer
  • Wiring harness
  • Screwdrivers
  • Wire stripper
  • Electrical tape
  • Multimeter

Step-by-Step Guide

Step 1: Understand the Tachometer Wiring

Tachometers typically have four primary wires:

  • Power wire: Supplies power to the tachometer
  • Ground wire: Provides a ground connection
  • Signal wire: Connects to the distributor
  • Lighting wire: Powers the tachometers backlight

Step 2: Locate the Distributor Signal Wire

The signal wire is the wire that connects the tachometer to the distributor, usually found in the ignition coil or directly on the distributor itself.

Step 3: Connect the Power Wire

Connect the power wire to a source of 12V power, which can be found in the fuse box or ignition switch.

Step 4: Connect the Ground Wire

Attach the ground wire to a clean, unpainted metal surface on the cars chassis.

Step 5: Attach the Signal Wire to the Distributor

Connect the signal wire to the negative terminal of the ignition coil or the distributors signal output.

Step 6: Connect the Lighting Wire

Wire the lighting wire to a source of 12V power that turns on with the vehicles lights.

Step 7: Test the Connections

Use a multimeter to test the connections and ensure that everything is wired correctly.

Common Issues and Troubleshooting

Tachometer Not Reading Correctly

If the tachometer is not reading correctly, check the signal wire and ensure its connected properly.

Intermittent Readings

Check the ground connection and ensure its secure and free from corrosion.

Tachometer Not Lighting Up

Ensure the lighting wire is connected to a proper power source and that the bulb inside the tachometer is functioning.

Maintenance Tips

Keep the wiring clean and secure, and periodically check for any signs of wear or damage.
