    How to test an ignition system? 

    1. Start by testing the Yamaha Raptor’s battery to ensure it has enough power to supply the ignition system. Use a multimeter to check the battery voltage. It should be around 12.6 volts for a fully charged battery.

    2. Next, check the condition of the spark plugs. Remove the spark plugs and inspect them for any damage or fouling. If they are damaged or fouled, replace them with new ones.

    3. Connect a spark plug tester to the spark plug wires. Crank the engine and observe the spark plug tester for a strong, consistent spark. If the spark is weak or intermittent, it indicates a problem with the ignition system.

    4. Check the condition of the ignition coil. Disconnect the ignition coil and test it using a multimeter. The coil should have a resistance of around 0.7 to 1.3 ohms. If the resistance is outside this range, the ignition coil may be faulty and needs to be replaced.

    5. Finally, test the ignition control module. This component controls the timing and firing of the spark plugs. Use a multimeter to test the module for any shorts or open circuits. If the module is faulty, it will need to be replaced.
