Installing a tachometer on your small engine is an easy task. Most engines come with the necessary hardware and instructions to do so, but it’s important that you have some basic knowledge about how they work before proceeding. This article will walk you through the process of installing a tachometer by giving you these 3 simple steps:

Steps to installing a tachometer on your small engine:
-Locate the spark plug wire.
-Identify where factory installed sensor is located at. This will be either under or next to the flywheel cover near the coil. You can use this as reference for installation.
-Once you have located the sensor under your flywheel cover, remove it and then use a wrench to tighten the tachometer onto it.
-Using a multi meter test for voltage on “B” terminal of coil (with key in off position) and check where ground is at (A).
-Use two wires to connect the ground to A and B. Black wire is always the power or hot side, while white is for neutral or common connection.
-Once you have connected all wires correctly turn key on and test again by starting your engine. If it does not start, check polarity of connections using a multimeter in “Diode” mode at each connection point.
-Once your engine is running and tested, then remove the key from the “On” position to test for a good idle speed at 700 RPM with a multimeter in Volts mode.
