Abstract
PURPOSE: To identify and indicate abnormal operation by thoroughly measuring working conditions of equipment in the charging system as loaded upon a vehicle employing a data processor.
CONSTITUTION: The voltage from an AC generator A terminal 40 is fed to a circuit 50 for determining the value of ripples at the charging, a circuit 51 for determining the width of the ripple width and a circuit 52 for determining the average charged value and then, the outputs of the circuits are transmitted to a data processor 55. On the other hand, the average voltage from the L terminal 41 is extracted 53 and fed to the device 55. The device 55 processes and computes the value and the width of ripples, the average charged voltage and the L terminal average voltage received and then, deliver the results to an indicator 56. The signal obtained from an ignition primary negative side terminal 42 through a signal shaping circuit 54 is used as the reference timing signal for determining the value of the ripples.
