As you can see testing a tachometer with a multimeter is not that difficult. All you need is to make sure that you have a good enough multimeter with frequency settings and a min/max hold feature. Hope this article has helped equip you with the necessary knowledge you would need to test tachometer with a multimeter correctly.

Strip the end of the tachometer signal wire and crimp on a small ring terminal. Locate a suitable ground connection near the ignition coil and attach the ring terminal to it. Make sure the connection is secure. Step 5: Test the tachometer. Start the engine and check if the tachometer is working properly.

Strip the end of the ground wire, and securely attach it to the grounding point using a ring terminal or grounding screw. Step 5: Finally, connect the signal wire of the wiring harness to the tachometer. Strip the end of the wire and attach it to the “Signal” terminal or wire on the back of the tachometer.

Step 3: Identify the tachometer signal wire. The tachometer signal wire is typically a green or blue wire that connects to the negative side of the ignition coil or the distributor. Use a wire stripper to remove a small portion of the wire’s insulation.
