1. Check Battery and Connections:
- Verify that the new battery is properly installed and its terminals are clean and tight. A weak or poorly connected battery can cause starting issues.
2. Ignition Switch:
- Ensure the ignition switch is turned to the "ON" position and that there are no loose connections or damaged wires around the switch.
3. Spark Plugs:
- Remove the spark plugs and check their condition. Look for signs of wear, fouling, or damage. If the plugs are old or worn, replace them.
Make sure the spark plug wires are properly connected.
4. Coil Inspection:
- Inspect the ignition coils for any signs of damage or corrosion. If there is any visible damage, replace the coils.
5. Check for Power to Coils:
- Use a voltmeter to check if the ignition coils are receiving power. Connect the voltmeter to the positive and negative terminals of the coils and turn on the ignition. You should see a voltage reading of around 12 volts. If there is no power to the coils, the issue could be with the ignition switch, wiring, or a faulty coil.
6. Test Spark Output:
- Remove one of the spark plugs and connect it to its spark plug wire. Hold the spark plug near the engine block while someone cranks the engine. You should see a spark jumping across the gap between the electrode and the engine block. If there is no spark, the problem may be with the ignition module, pick up coil, or other ignition components.
7. Pickup Coil and Wiring:
- Inspect the wiring harness and connectors related to the pickup coil. Ensure there are no broken or loose wires. The pickup coil converts engine movement into an electrical signal used by the ignition system. A faulty pickup coil or wiring could cause a no-spark condition.
8. Ignition Module:
- The ignition module controls the timing of the spark. Test the ignition module by following the manufacturer's specifications. If the module is faulty, replace it.
9. Electrical Connections:
- Check all electrical connections, grounds, and connectors related to the ignition system. Sometimes, a loose or corroded connection can disrupt the flow of electricity and lead to a no-spark condition.
10. Consult a Professional:
- If you've tried all the above steps and still don't have spark, it's advisable to consult with a professional mechanic or motorcycle technician who has experience with older motorcycles like the v65 magna.
Remember that diagnosing a no-spark condition can be complex, and multiple factors could be contributing to the problem. If you are unsure about any of the steps or don't have the necessary tools or experience, seek help from a qualified technician.
