Toyota Avalon Alternator Brush

The Toyota Avalon Alternator Brush allows the alternator to keep battery current flowing while also helping to power every other electrical load on request by maintaining contact between the slip rings that rotate and the stationary field circuit. The Alternator Brush, made of conductive carbon, rides on the shaft-mounted rotor. This allows current to flow into the field windings. Meanwhile, the belt-driven rotor spins inside the stator. This creates the magnetic flux that is the input to the AC output. The diodes immediately convert this to DC, which is for the battery. Replacement of worn down Alternator Brush with an appropriate substitute restores proper field current very quickly and within a low-cost replacement. The early Toyota Avalon models applied a straightforward dual carbon Avalon Alternator Brush connected to either an internal or external voltage regulator, whereas recent Avalons still use the same carbon composition brush but instead operate with a regulator function run by the powertrain control module, eliminating separate hardware and tightening voltage accuracy. Because Toyota has not altered the dimensions of the brushes, replacing one generation of Alternator Brush with the next is just a matter of bolt-out bolt-in, which typically takes less than two hours with basic tools.
