Abstract
Abstract A polarity indicating battery booster assembly including a pair of booster wires with a first pair of battery clamps connected on one end and a second pair of battery clamps connected at the other end. A first light is connected to the pair of wires for indicating one polarity of connection of the first pair of battery clamps while a second light is connected to each of the wires for indicating the opposite polarity of connection of the first pair of battery clamps. Additional first and second lights are provided for determining the polarity of connection of the second pair of battery clamps. One of the second pair of battery clamps carries an electrical probe for checking polarity of that clamp. The first lights are green light-emitting diodes, and the second lights are red light-emitting diodes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A polarity indicating battery booster cable assembly, comprising: (a) a pair of booster wires having first ends and second ends, (b) first battery attachment means connected to the first ends of the pair of booster wires, (c) a first indicating means operatively connected to the first battery attachment means for indicating the polarity of connection of the first battery attachment means, (d) a second battery attachment means connected to the second ends of the pair of booster wires, the pair of booster wires providing continuous uninterupted electrical connections between the first and second battery attachment means, and (e) a second indicating means operatively connected to one of the booster wires and including a test probe for determining the polarity for connection of the second battery attachment means.
Claim 2
Dependent Claim
127 words
A polarity indicating battery booster cable assembly, comprising: (a) a pair of booster wires having first ends and second ends, (b) first battery attachment means connected to the first ends of the pair of booster wires, (c) a first indicating means operatively connected to the first battery attachment means for indicating the polarity of connection of the first battery attachment means, (d) a second battery attachment means connected to the second ends of the pair of booster wires, the pair of booster wires providing continuous uninterupted electrical connections between the first and second battery attachment means, and (e) a second indicating means operatively connected to one of the booster wires and including a test probe for determining the polarity for connection of the second battery attachment means.
Claim 3
Dependent Claim
95 words
A polarity indicating battery booster cable assembly, as defined in claim 1, in which: (f) the first indicating means includes: 1. a first light for indicating one polarity of connection of the first battery attachment means, and 2. a second light for indicating the opposite polarity of connection of the first battery attachment means, and (g) the second indicating means includes: 1. a first light for determining one polarity of connection of the second battery attachment means, and 2. a second light for determining the opposite polarity of connection of the second battery attachment means.
Claim 4
Dependent Claim
53 words
A polarity indicating battery booster cable assembly, as defined in claim 2, in which: (h) the second battery attachment means includes: 1. a first battery clamp connected to one of the booster wires, and 2. a second battery clamp connected to the other booster wire, the second battery clamp carrying the test probe.
Claim 5
Dependent Claim
38 words
A polarity indicating battery booster cable assembly, as defined in claim 3, in which: (i) the test probe includes an electrically conductive terminal electrically connected to the second indicating means and electrically isolated from the second battery clamp.
