- 30 - ABSTRACT OF THE DISCLOSURE This specification discloses a vehicle elec- trical system tester which connects in parallel across the vehicle battery and the portion of the electrical system to be tested and measures voltages upon selective actuation of portions of the vehicle electrical system as determined by individual characteristics of a parti- cular vehicle electrical system. Comparison of these measured voltages with predetermined values is used in evaluating whether the electrical system is operating properly. The vehicle electrical system tester and a memory are packaged in a portable measuring unit which is periodically coupled to an anlyzer for anlyzing measured voltage data and updating instructions for the portable measuring unit. The analyzer can determine a pattern of recurring faults and provide information to correct the manufacturing process to remove the faults. The method of testing using the apparatus includes measuring a voltage level after connection of the apparatus as a function of actuation of a portion of the vehicle electrical system, comparing the voltage difference to a predetermined voltage magnitude, and determining if the actuated portion of the electrical system is operating properly.
