ABSTRACT:
An alternator produces current that has an average component and a ripple component. The alternator testing apparatus produces one voltage representative of the magnitude of the peak-to-peak amplitude of the ripple component and a second voltage representative of the sum of the average component and the peak-to-peak amplitude of the ripple component. A series of comparators each have their signal inputs coupled to receive the first voltage and their control inputs coupled to a divider network which is in turn coupled to receive the second voltage. Indicators are coupled to the comparators.
