Abstract
An engine starter apparatus includes a starter motor, a temperature sensor configured to detect a temperature of the starter motor, a light source integrated with the starter motor, and a controller operatively connected to the temperature sensor and the light source. The controller is configured to illuminate the light source in a first color in response to the temperature of the starter motor exceeding a first temperature threshold. The controller is configured to illuminate the light source further in a second color in response to the temperature of the starter motor exceeding a second temperature threshold. The second temperature threshold is greater than the first temperature threshold. The first and second color are different. The second temperature threshold corresponds to a life limit of the starter motor. Illumination of the light source indicates an overheated starter motor, which may warrant a replacement of the starter motor.
