Abstract
A safety booster cable assembly for connecting a d.c. source to a receiving battery including a normally open relay interrupting the electrical connection between one of the two pairs of electrodes. Circuitry is provided for closing the contact of the relay when the electrodes being connected are of similar polarities. Time delay circuitry is included so that the relay contact is closed after a certain predetermined amount of time has passed so that sparks are prevented from the movement or scratching of the cable clips on the electrodes. Light emitting diodes are connected between the electrodes of the D.C. source and receiving battery so that they illuminate when the correct polarity is observed in the connection of the cable clips.
