When you turn the key of your Acura, you simply expect it to start. This would not be possible without the Acura starter, however. This device uses the energy of the battery to turn the engine over in the morning, as long as the battery has been fully charged by the alternator. The starter is very similar to the electric motors used by many children's toys. The casing contains a series of permanent magnets. The center core, which is allowed to rotate, is made of iron or steel, and is wound in copper wires. When power is transferred to the core, the permanent magnets alternately repel and attract the core, resulting in a fluid motion. Once the Acura starter starts turning, the pinion gear is extended into the flywheel of the engine. When the power is transferred from the Acura starter to the engine, the engine turns over and the self-sustaining process of internal combustion takes over. When the Acura starter fails, it is usually due to one of two reasons. The first is friction wear on the teeth of the pinion gear, which gets serious enough that the Acura starter can no longer transfer its power to the flywheel. The second failure point is the brushes within the Acura starter. These small pieces of flexible metal will wear from friction and loose their flexibility as the vehicle ages, leaving the Acura starter with no power.
