1. A device for testing a voltage level in an electrical terminal cavity, the device comprising:
a testing body;
a probe for contacting the electrical terminal cavity, the probe comprising:
a tip portion configured to contact the electrical terminal cavity, wherein the tip portion comprises a first cross-sectional area along a length of the tip portion;
a base portion configured to connect the probe to the testing body, wherein the base portion comprises a second cross-sectional area along a length of the base portion;
an intermediate portion extending from the tip portion to the base portion, wherein the intermediate portion comprises a third cross-sectional area along a length of the intermediate portion, wherein the first cross-sectional area is smaller than the third cross-sectional area, wherein the third cross-sectional area is smaller than the second cross-sectional area, and wherein the intermediate portion is concentric with the tip portion and the base portion; and
an axis extending between a center of the tip portion, a center of the intermediate portion, a center of the base portion, and a center of the testing body; and
a circuit disposed within the testing body, wherein the circuit is operatively coupled with the probe such that circuit is configured to sense the voltage level in the electrical terminal cavity.
