A magneto is an electrical device that generates electricity from magnetism. It is typically used in internal combustion engines to provide the spark that ignites the air-fuel mixture. Magnetos are also used in some types of generators and other electrical devices.
Checking a magneto is important to ensure that it is functioning properly and that the engine is running smoothly. There are a few different ways to check a magneto, but the most common method is to use a multimeter. A multimeter is a device that measures electrical current, voltage, and resistance. To check a magneto with a multimeter, follow these steps:
- Set the multimeter to the AC voltage setting.
- Connect the positive lead of the multimeter to the output terminal of the magneto.
- Connect the negative lead of the multimeter to the ground terminal of the magneto.
- Start the engine and observe the reading on the multimeter. The reading should be between 12 and 15 volts.
If the reading is not between 12 and 15 volts, then the magneto may not be functioning properly. It is important to have the magneto checked by a qualified mechanic if you are experiencing any problems with the engine.

Tips for Checking a Magneto
Checking a magneto is an important part of maintaining an internal combustion engine. A magneto is an electrical device that generates the spark that ignites the air-fuel mixture in the engine. If the magneto is not functioning properly, the engine will not run smoothly.
Here are five tips for checking a magneto:
Tip 1: Check the voltage output.The voltage output of the magneto should be between 12 and 15 volts. To check the voltage output, use a multimeter to measure the voltage at the output terminal of the magneto.Tip 2: Check the continuity.The continuity of the magneto should be checked to ensure that there is no open circuit. To check the continuity, use a multimeter to measure the resistance between the output terminal and the ground terminal of the magneto.Tip 3: Check the ground connection.The ground connection of the magneto should be checked to ensure that it is making good contact. To check the ground connection, use a multimeter to measure the resistance between the ground terminal of the magneto and the engine block.Tip 4: Check the points.The points are a set of electrical contacts that open and close to create the spark. The points should be clean and free of corrosion. To check the points, use a feeler gauge to measure the gap between the points.Tip 5: Check the condenser.The condenser is a capacitor that stores electrical energy. The condenser helps to create a strong spark. To check the condenser, use a multimeter to measure the capacitance of the condenser.
By following these tips, you can check the magneto on your engine to ensure that it is functioning properly. If you are experiencing any problems with the engine, it is important to have the magneto checked by a qualified mechanic.
Summary of key takeaways or benefits:
- Checking a magneto is an important part of maintaining an internal combustion engine.
- By following these tips, you can check the magneto on your engine to ensure that it is functioning properly.
- If you are experiencing any problems with the engine, it is important to have the magneto checked by a qualified mechanic.
Transition to the article’s conclusion:
Checking a magneto is a relatively simple procedure that can be performed by anyone with basic mechanical skills. By following these tips, you can ensure that your magneto is functioning properly and that your engine is running smoothly.
