STARTER DIAGNOSTICS METHOD Russian patent published in 2019 - IPC G01R31/00 G01M13/00 

FIELD: vehicle equipment and accessories.

SUBSTANCE: invention relates to technical diagnostics and can be used to determine technical state of starter directly on object, for example, automobile. Method for starter diagnostics consists in the fact that the accumulator battery EMF is measured, on the vehicle the condition for starter checking in the full braking mode is created, for which the engine is completely decelerated, the instrument and starter switch is turned to the engine start position, wherein the starter gear engages with the engine flywheel rim teeth, which is completely braked through the vehicle transmission and tries to rotate it. As the engine is completely braked, the starter gear can not turn the flywheel of the engine and in this case through the starter there will be flow of full braking, which is registered by an ammeter. In starter full braking mode, full starter deceleration current is measured to calculate maximum electromagnetic power of starter. Diagnostic time does not exceed 3–5 seconds, the accumulator battery is charged. Further, the obtained data are compared with the reference data for the diagnosed starter and its technical state is stated.

EFFECT: development of present invention is aimed at improvement of reliability of control of starter technical condition, reduction of labor intensity during diagnostics works.
