ABSTRACT:
An alternator-battery electrical system test apparatus which, in one modification, includes a four stage voltage level sensing system, each stage being operative in response to a particular condition of the electrical system under test. The first stage senses the filtered and unfiltered output of the alternator to provide a pulsed output which provides an indication of any diode failure or winding failure in the alternator. The remaining three stages sense the voltage output from the alternator as compared to a fixed reference, each particular voltage condition providing an indication of a preselected electrical condition within the circuit. The entire system is calibrated by a single calibrating resistor. The second modification of the system provides two outputs, one output indicating a regular defect and a diode condition indicator and the other indicator providing an indication of no defects in the system if conducting alone, or an alternator defect if conducting simultaneously with the above mentioned one output. The circuit is substantially identical to the first modification, with certain elements eliminated.
