1. Battery contacting probe apparatus for use in a battery tester comprising:
- an actuator;
a pair of opposed probe arms, each of said probe arms having an electrical contact on an end thereof;
said actuator operatively connected to said probe arms wherein movement of said actuator biases said ends of said probe arms away from each other to an open position allowing the electrical poles of a battery to be tested to be contacted by said contacts on said probe arms and wherein said actuator comprises a rack and pinion gear system.

Abstract
A combination battery, light bulb, fuse tester having novel features. In particular, the tester includes a novel probe apparatus including an actuator, a pair of opposed probe arms, each of the probe arms having an electrical contact on an end thereof, the probe arms being adapted such that operation of the actuator biases the ends of the probe arms away from each other to an open position allowing the electrical poles of a battery, light bulb, or fuse to be tested to be contacted by the contacts on the probe arms. Additional features include magnetic probe contacts to facilitate the testing of a battery, light bulb, or fuse.

34. A battery, bulb or fuse testing apparatus comprising:
-
a case;
a pair of movable opposed probe arms coupled to said case, each probe arm having an electrical contact;
a movable actuator fixedly and generally non-removably coupled to at least one of said case or at least one of said pair of movable arms, wherein operation of said actuator causes both of said probe arms to move away from each other an relative to said case to receive a battery, bulb or a fuse therebetween; and
a circuit electrically coupled to said electrical contacts, wherein said probe arms, electrical contacts and circuit are arranged such that during operation a current is passed to one probe arm, from said one probe arm through a battery, intact bulb or intact fuse located between said probe arms and that is in electrical contact with said electrical contacts and from said battery, intact bulb or intact fuse to the other one of said probe arms. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
