The complexity of conducting an expert examination of fires that occur in cars and determining the technical cause of the fire is due to the presence of numerous electrical devices in their design. One of these devices is a starter, which converts the electrical energy of the battery into the mechanical energy of rotation of the engine crankshaft. The operation of the starter is accompanied by the release of high power in a small volume in a short period of time. In the electrical circuit of the car, the starter does not have protection against overcurrents and short-circuit currents. The practice of fire investigation shows that these devices often cause a fire in motor vehicles. Based on the analysis of the data obtained during the examinations, the main causes of fire-hazardous emergency processes in automobile starters were established. Also, the characteristic signs of these processes that can be detected after a fire within the framework of complex fire-technical and auto-technical examinations are revealed.
