Abstract
An automotive vehicle electrical system tester includes a starter motor or charging system voltage measurement circuit configured to measure a voltage of an electrical system of a vehicle. A microprocessor is configured to diagnose the electrical system as a function of the measured voltage and responsively output the diagnosed condition on a display. The microprocessor is further configured to encrypt the diagnosed condition and responsively output encrypted information related to the condition.
