Abstract: An electrical power connection module adapted to indicate when a weld between a pin and a socket has occurred. The present invention provides a multiple pin plug wherein each pin mounted in the plug is attached thereto using a spring means. The biasing means is adapted to maintain the pin in a first position if a weld has not occurred, and a second position if a weld has occurred to thereby provide the user with a visual indication of the welded pin. Therefore, rather than requiring that an entire line replaceable unit be removed and replaced at substantial cost and delay, the present invention allows the user to quickly determine which pin has become welded, and to quickly disconnect the welded pin from the plug for removal of the plug and then subsequent removal of the welded pin.
