Cable jumper without polarity

Abstract

The invention relates to a battery cable jumper arrangement. The arrangement has a first pair of cables and clamps at the connecting ends of each cable of the first pair of cables to connect each cable end to a respective terminal of a source of D.C. power. The arrangement further includes a second pair of cables with clamps at the connecting ends of each cable of the second pair of cables for connecting each cable end to a respective terminal of a battery to be recharged. A first sensor, such as a three-position solenoid, senses the polarity of connection of the first pair of cables at the source of power, while a second sensor, such as a three-position solenoid, senses the polarity of connection of the second pair of cables at the battery. A switching arrangement, for example, an interconnected set of double pole double throw switches, driven by the first and second sensor, are actuated by the sensors to ensure correct polarity of connection between the power source and the battery regardless of the polarity of connection of either the power source or the battery.
