Vintage Tachometer Wiring Diagram

By | September 19, 2022



When wiring up a vintage tachometer, the first thing to consider is the wiring diagram. This diagram is usually provided with the product, or can be downloaded online. It outlines how the components of the tachometer should be connected. Knowing the right way to connect the wiring is important for correctly setting up and maintaining the tachometer.

Every tachometer wiring diagram is unique, so it's important to understand which components need to be connected and in what order. To start, a ground wire should always be wired from the negative terminal on the tachometer to a known good earth ground. From here, wires must be connected to the ignition coil, ignition switch, and 12-volt power source (battery or alternator). Each connection should be made according to the wiring diagram for the specific product.

Finally, double check the connections. Matted wires and loose terminals can lead to blown fuses or other problems, so ensure all wiring is securely fastened before powering up the tachometer. With these steps, you can properly wire up a vintage tachometer and make sure everything is running safely and efficiently.
