The Electronic Specialties LOADpro and Back Probe Kit, No. 187, is designed to help technicians diagnose electrical problems. The kit includes LOADpro test leads, LOADpro tip adapters, flexible silicon back probes, spoon probe curved back probes, large crocodile clips, and push-on alligator clips. The test leads allow users to instantly load the circuit to see if current can flow and can work with almost any digital multimeter. LOADpro is able to find high corrosive resistance, shorts to ground, and open circuits quickly and easily by simply just reading the voltage, the company says.
