Patent Images
1. A test probe comprising:
- (a) a probe element configured to contact an electrical surface;
(b) a circuit configured to determine if the electrical surface has a positive or negative polarity;
(c) an indicator configured to provide an indication of the determined positive or negative polarity;
(d) first and second connectors, either one of said first and second connectors configured to be connected to a power source and the other of said first and second connectors configured to be connected to ground; and
(e) a light source provided adjacent to the probe element and configured to provide a light output when the one of said first and second connectors is connected to the power source and the other of the first and second connectors is connected to the ground.

Abstract
An electronic voltage polarity indicator that provides an easy to identify indication as to whether an electrical surface being contacted by a probe is at a positive or negative polarity. The electronic voltage polarity indicator is particularly useable with a 12 volt power source, and thus can find application in the installation of equipment in vehicles, such as automobiles.

17. A test probe comprising:
-
(a) means for contacting an electrical surface;
(b) means for determining if the electrical surface has a positive or negative polarity;
(c) means for providing a first indication of the determined positive or negative polarity; and
(d) first and second means for connecting, either one of said first and second means for connecting for providing a connection to a power source and the other of said first and second means for connecting for providing a connection to ground;
(e) means for providing a light output, provided adjacent to the means for contacting an electrical surface, when the one of the first and second means is connected to the power source and the other of the first and second means is connected to the ground.
