Abstract
Abstract An improved jumper cable organization is presented wherein illuminated indication is included to discourage improper connection of the improved jumper cable apparatus to associated batteries. A first embodiment of the invention includes a clamp securable to a jumper cable electrical conductive line wherein a spike is electrically associated with a plurality of LED units such that the spike electrically associated with an associated clamp may be contacted to a remaining terminal of a battery once the three remaining jumper cable clamps are secured to indicate appropriate polarity connection of the jumper cable organization. A second embodiment positions the plural LED elements within the handle of a battery connective clamp where an electrically isolated probe may be contacted to the remaining battery terminal for indication of appropriate polarity. The aforenoted LED elements with inappropriate connection of the jumper cables of the instant invention will illuminate to indicate an inappropriate polarity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
250 words
An automotive jumper cable apparatus for use with direct current batteries comprising, a first electrical conductive cable formed with first and second ends, and a second electrical conductive cable formed with third and fourth ends, and first and fourth battery connector clamps are secured to said first and second ends respectively and second and third connector clamps are electrically secured to said third and fourth ends respectively; said first second battery connector clamps comprise a first clamp couple means for attachment to respective terminals with a first direct current battery and said third and fourth battery connector clamps comprise a second couple means for attachment to a second direct current battery, and a polarity indicator means electrically associated with said fourth battery connector clamp for testing polarity connection of said first and second battery clamp couples, and said polarity indicator means including a LED element means electrically associated with a conductive probe means including an electrical insulator between said probe means and said fourth battery connector clamp; said probe means positioned for temporary contact with a remaining battery terminal of said second battery when said first and second battery connector clamps are secured to said first battery and said third battery connector clamp is secured to a single terminal of said second battery, and wherein said polarity indicator means includes a torquing strap for securement about said first electrical conductive cable including a spike for penetration into said cable for providing electrical communication between said cable and said LED elements.
