How do you check a motorcycle ignition coil?
How to Check a Motorcycle Ignition Coil
- Turn off the motorcycle ignition.
- Disconnect the spark plug wires from the coil by hand.
- Measure the resistance between the coil connections for the spark plugs with an ohmmeter.
- Measure the resistance between the two smaller primary wire connections on the coil with an ohmmeter.
Can you test a coil with a spark plug?
Testing the Coil You don’t have to remove the coil in order to test it. It can be done by checking the spark plugs. For this test, you’ll need a pair of safety goggles, some insulated pliers, a spark plug socket tool, and a helper.
How many ohms should a pickup coil have?
The proper pick up coil resistance for either coil should be in range from 350 to 700Ω.
When do you test the ignition coil on a motorcycle?
Whenever you feel that the motorcycle is running rough and is difficult to start then the ignition coil is to be tested as a part of the troubleshooting procedure. The main purpose of the ignition coil is to step up the low battery voltage to high which is needed to spark plug.
Where is the ignition coil on a moped?
In order to access the spark plugs and coil, remove the bike seat as well as the fuel tank. There are some bikes where the ignition coil is located under the flywheel and those are mostly mopeds. Step 3) The plug cap is to be removed for the test, if it is not removed then it can make your test inaccurate.
What should coil resistance be on motorcycle spark plugs?
Measure the resistance between the coil connections for the spark plugs with an ohmmeter. The resistance should be 0.5 to 3 ohms. A resistance outside of this range indicates a broken coil. Measure the resistance between the two smaller primary wire connections on the coil with an ohmmeter.
What is the purpose of the ignition coil?
The main purpose of the ignition coil is to step up the low battery voltage to high which is needed to spark plug. It is advised to test the coil when the coil is hot.
