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.

A heat sink assembly for an alternator. The heat sink assembly includes a clip for clipping the heat sink assembly onto a diode rectifier heat sink of the alternator. Thermally conductive material is on an inner surface of the clip. A heat sink is on an outer surface of the clip opposite to the thermally conductive material, and includes fins. Thermal energy from a hotspot of the alternator to which the heat sink assembly is clipped is conducted to the heat sink by way of the thermally conductive material and is radiated from the fins to cool the hotspot.
