How to Test the Pickup Coil on Your ATV
Understanding the Pickup Coil
The pickup coil, also known as the ignition sensor, plays a pivotal role in your ATV’s ignition system. It generates a voltage signal that tells the ignition system when to fire the spark plugs. If this component is malfunctioning, it can lead to a range of issues, from poor engine performance to complete failure to start. Knowing how to test the pickup coil will help you diagnose problems quickly and effectively.
Preparation Steps
Before you start testing, ensure you have everything ready. Follow these steps to prepare:
- Gather your tools: multimeter, screwdrivers, wrenches, and safety glasses.
- Consult your ATV’s service manual for specific details about the pickup coil location and specifications.
- Disconnect the battery to prevent any electrical shorts.
Locating the Pickup Coil
The pickup coil is typically located near the flywheel or stator of the engine. Here’s how to find it:
- Remove any necessary covers or panels to access the engine.
- Look for the stator assembly, which is usually mounted on the side of the engine.
- Identify the pickup coil, which will have two or three wires leading to it.
Testing the Pickup Coil
Now that you have located the pickup coil, it’s time to test it. Follow these steps:
Step 1: Set Up the Multimeter
Set your multimeter to the resistance (ohms) setting. This will allow you to measure the resistance of the pickup coil.
Step 2: Measure Resistance
Disconnect the wires from the pickup coil. Use the multimeter probes to measure the resistance between the terminals of the pickup coil. Refer to the specifications in your service manual for the correct resistance values.
| ATV Model | Pickup Coil Resistance (Ohms) |
|---|---|
| Honda TRX 450R | 100-200 |
| Yamaha Raptor 700 | 150-250 |
| Polaris Sportsman 500 | 120-220 |
| Kawasaki Brute Force 750 | 130-230 |
| Can-Am Outlander 650 | 140-240 |
Step 3: Interpret the Results
Compare the resistance reading from your multimeter to the specifications in your service manual. If the reading is significantly outside the specified range, the pickup coil is likely faulty and needs replacement.
Testing for Voltage Output
In addition to measuring resistance, you can also test for voltage output. This step will help confirm the pickup coil’s functionality.
Step 1: Reconnect the Wires
Reconnect the wires to the pickup coil. Make sure the connections are secure.
Step 2: Set Up the Multimeter
Switch your multimeter to the AC voltage setting.
Step 3: Crank the Engine
With the multimeter probes connected to the output wires of the pickup coil, crank the engine. You should see a voltage reading on the multimeter.
Step 4: Check the Specifications
Refer to your service manual for the expected voltage output. If you see no voltage or a reading below the specified range, the pickup coil is likely defective.
Final Steps
If your tests indicate that the pickup coil is faulty, it’s time to replace it. Here’s a quick guide on how to do that:
- Remove the old pickup coil by unscrewing it from its mounting location.
- Install the new pickup coil, ensuring it is properly aligned and secured.
- Reconnect all wires and components you removed during the testing process.
- Reconnect the battery and start the engine to verify proper operation.
Testing the pickup coil on your ATV is a straightforward process that can help you maintain optimal performance. By following these steps, you can diagnose issues quickly and keep your ATV running smoothly.
