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.
