Abstract
The integrity and connection of cable wires (10-13) extending between two banks of terminals (20-1 to 20-4 and 16-19) are checked for shorts of the wires to ground, to battery wiring between each other and for opens and misconnections or cross-connections of the wires. Unique recognition circuits are provided for controlling, analyzing (circuits 43, 53, 68, 92, 112, 181) and displaying (displays 23, 24, 31 and 32) the test results to accordingly apprise an operator(s) stationed at either or both ends of the cable.
