Abstract
A circuit tester device for testing continuity and polarity of vehicle relay circuits may include a housing and a plug carried by the housing. The circuit tester device may also have a battery lead adapted to connect to a battery terminal, and a ground lead adapted to connect to a ground. Further, the circuit tester device may have circuitry including three or more circuits connected between the battery and ground leads. Each circuit may have in series a first resistor, a first status indicator, a first diode, a test terminal, a second diode, a second status indicator and a second resistor. Each test terminal may be connected to a respective one of the pins. The circuitry may also have one or more load circuits tapped into one of the circuits between the first and second diodes. The load circuits may include in series a test switch and a load terminal.
