Abstract:
1. A handheld circuit tester for an automotive electrical system having circuit portions respectively operable at a first nominal voltage range with respect to ground and a second nominal voltage range with respect to ground, the tester comprising: an elongated, curved handle portion, the handle portion being substantially in the shape of a screwdriver handle; a probe device, substantially in the shape of a screwdriver shank, the probe device coupled to the handle portion and is capable of contacting a circuit point of an automotive circuit; a ground device coupled to the handle portion and capable of being securely attached to a ground point; and circuitry disposed within the handle portion and operatively coupled to the probe device and the ground device, the circuitry being configured to sense voltage at the circuit point and to indicate whether the sensed voltage corresponds to the first or second nominal voltage range.
