Toyota MR2 Alternator Brush

The Toyota MR2 Alternator Brush ensures constant battery charging by making continuous live contact with the rotating slip rings, allowing current to flow into the rotor field and regulate output. Every generation of the sporty MR2 has the Alternator Brush located in the rear section of the alternator housing next to the rectifier diodes. It has carbon shoes that are pressed by springs against the rotating rings. These feed field amperage, which the voltage regulator adjusts for turning the alternating current from the stator into the stable DC that the car needs. When the brushes wear down, the alternator may undercharge. However, replacing that with a new Alternator Brush is much quicker and cheaper than a whole alternator replacement and can be done in under two hours using basic hand tools. Prior Toyota designs featured either separate or internal regulators. However, later designs instituted regulation within the engine control computer. Regardless, the Alternator Brush maintains the same basic function. Alternative brush styles are not available for different years of the Toyota MR2. The variations are mainly in the length and lead attachment, so confirming the fitment ensures the spring keeps the Alternator Brush firmly on the slip rings and restores dependable voltage.
