What is a Spark Plug Tester?
A spark plug tester is a tool used to check the quality of a spark plug. It is a small device that you can use to test the spark plug’s functionality without removing it from your engine. It measures the electrical current that flows through the spark plug.
Why do You Need a Spark Plug Tester?
If your engine is not running smoothly, it could be due to a faulty spark plug. By using a spark plug tester, you can determine whether or not the spark plug is working correctly. This will save you time and money, as you won’t have to replace the spark plug unnecessarily.
How to Use a Spark Plug Tester?
To use a spark plug tester, follow these simple steps:
Step 1: Turn Off the Engine
Before you start testing the spark plug, make sure the engine is turned off. This will prevent any accidents from happening.
Step 2: Remove the Spark Plug Wires
Next, remove the spark plug wires from the spark plugs. Make sure you label the wires so that you know which one goes where.
Step 3: Connect the Spark Plug Tester
Connect the spark plug tester to the spark plug wire. The tester should have a clip that you can attach to the spark plug wire.
Step 4: Ground the Tester
Ground the spark plug tester by attaching the other end of the tester to a metal part of the engine. This will provide a path for the electrical current to flow.
Step 5: Start the Engine
Start the engine and observe the spark plug tester. You should see a bright blue spark jumping between the tester’s terminals.
Step 6: Repeat the Test
Repeat the test for each spark plug wire. Make sure you reconnect the wires after you’re done testing them.
