Alternator brushes: replacement and selection

When and why it is necessary to replace alternator brushes

The alternator brushes have no lifetime limit specified and are to be replaced in case of significant abrasion of old ones. Specialists recommend to perform inspection of brushes condition every 4 years or 50 000 kilometers of mileage.

The cause of brushes premature breakdown is failures in alternator operation. In particular, inter-turn short circuit of a stator or rotor can cause negative impact on parts condition.

The signs of brushes wear-out are insufficient battery charge or its absence, voltage fluctuations in the car mains. Sudden turning off of electric equipment or dimming of light in the cabin or headlights can be noticeable during this.

Works on components installation are performed at a car servicing station. This is determined by necessity of alternator demounting and inaccessibility of the components, fastened in the brush holder. In the process of new elements installation it is recommended to assess condition of the diode bridge.

By necessity, this component should be replaced too. Pay attention: if the brushes are combined with the regulator relay – this unit is replaced as an assembly.
