Provided is a warning device for automobile alternator replacement which warns a driver of the replacement timing of an automobile alternator in advance. A conducting sensor that surrounds a conductor with an insulator is embedded into a brush so that the conducting sensor can be electrically conducted before the brush reaches its wear limit. A push switch is installed between the brush and a brush holder so that the push switch can be turned on before the brush reaches its wear limit. The conducting sensor or the push switch is connected to a warning unit so that the warning unit can be operated when the conducting sensor is electrically conducted or when the push switch is turned on. Thereby, the warning device can warn the driver to replace the alternator before the alternator becomes inoperable due to the wear of the brush.
