摘要： A tester includes a housing containing a passive test circuit including a plurality of LEDs respectively connected to terminals of a multi-terminal connector jack (39) on the housing for connecting the tester, by means of an associated cable harness, between a keyswitch module and other electronic circuits on an associated vehicle to be tested. Different harnesses may be provided, tailored to different vehicles. The test circuit is powered by a battery on board the vehicle and includes indicators dedicated to checking to see if the battery charging circuit on the vehicle is operating properly. The remaining indicators check different circuits, depending upon the override switches associated with certain ones of the indicators and a test switch for simultaneously energizing all of the indicators. A relay (52) shorts two of the jack terminals until the tester is powered, the cable harness including a diode across those terminals which is normally shorted out and is placed in circuit when the relay is energized.
