Flywheel Servicing In order to produce the voltage necessary to run an ignition system, the flywheel magnets must be of particular strengthWeak flywheel magnets can cause low ignition voltage, which could affect motor performanceWeak flywheel magnets can also cause low readings on ignition test equipment, such as the peak-reading voltmeter, which may cause unnecessary replacement of ignition componentsFlywheels rarely go bad and would only be replaced as last resort in solving an ignition problemAn accurate test of alternator output can help determine the flywheel's conditionRefer to Running Test, Alternator Output, Section 8Removal
