1. Apparatus for jumping a first battery to a second battery comprising:
- a first and second electrical jumper cable secured together throughout a substantial length thereof;
a manually operable clamp secured to each end of each jumper cable to connect the jumper cable ends to battery terminals;
switch means having contacts interposed in a circuit path of the second jumper cable having normally open contacts to open the electrical circuit of the second jumper cable thereby providing a first and second section thereof;
first serially connected electrical diode and indicator means connected to the first cable and the first portion of the second cable;
second serially connected electrical diode and indicator means connected to the first cable and the second portion of the second cable;
each of said diodes being connected to conduct electrical current in the same direction relative to their respective connections between the first and second cables;
manually operable means to control the said switch means;
spring means connected to urge the manually operable means to a first position whereby the switch means contacts are in their normally open position; and
means whereby the manually operable means may be manually moved to a second position to close the contacts of the switch means to close the circuit path of the second jumper cable.
