Claims

[Scope of utility model registration request]

A means for detecting the cranking rotation speed of an automobile starter, a means for diagnosing the rotation speed by comparing it with a specified value, and a means for detecting a voltage applied to a coil of a magnetic switch of the starter, and the detected voltage is equal to the specified value. In a diagnostic device that has a means for comparing and diagnosing, a means for detecting a contactor voltage drop of a starter magnet switch, and a means for comparing and determining the voltage drop value with a specified value, the current detected by the means for detecting the current during cranking is 1. A starter diagnostic device for an automobile, characterized in that the device determines which current value falls within a specified range, and lights up lamps arranged in the order of current indicating main failure details.
