how to troubleshoot a magneto ignition

Youll also need a flat workspace, such as a garage floor, driveway, or street parking. In the magneto above, the armature is shaped like the capital U. Two ends of the U point towards the flywheel. The validity of the method is demonstrated through application to test the -D case data and to remove discrepancies from the ditto ridge. Whether you start the engine with a pull rope or the turn of a key on an electric start motor, you're relying on the ignition system to produce a spark inside the combustion chamber. Faulty plugs put a higher load on the system and can cause issues such as overheating. You may have a similar issue if your battery isnt powerful enough to meet the demand of cranking the motor. If mounted on the firewall, the interference signals have to travel back through the firewall, engine mount, engine, and magneto. SPARK PLUG 4. When it does fail, it is usually due to heat caused by plugged cooling fins or improper wiring of the ground wire to battery voltage. This increases the voltage in the condenser. When the plugs check out, its time to start working back through the chain by testing the links between. Very informative blog. It is the only part that has exposed copper windings. The flywheel shroud is a metal casing that covers the magnetic and is kept in place with three bolts. Homework and the written word are overwhelming! Ignition system testing, Magneto coils, Points and CDI Hook the tester up between the ignition cable and the spark plug and start the engine. Safety Warnings: We would recommend having the transformer coil rewound as modern class F or H wires and insulations are superior to the ones used at the time it was originally made and would almost certainly give you another 40 years of good service. Required fields are marked *. Loosely bolt on Coaxial capacitors are more effective at radio frequencies. The battery ignition system is used in cars and light trucks. This can mask a fault on these cars as the vehicle will continue to run until the other fails. Capacitance coupling transfers electrical energy between the two circuits. The point were making is that you need to treat every ignition problem as a case-by-case scenario. The process of checking the distributor is dependent on the application you have to work with.
