Electronic Specialties' LOADpro Dynamic Test Leads, No. 180, allow users to instantly load the circuit to see if current can flow. LOADpro leads are designed specifically for finding wiring faults in automotive and heavy-duty vehicles and equipment. The LOADpro finds high corrosive resistance, shorts to the ground and open circuits more quickly. Using almost any digital multimeter, the LOADpro can locate corrosion in wiring with just by pressing the switch. LOADpro Test Leads also feature SteadyPin Probe Tips. Instead of a pointed probe, SteadyPin tips have a small recess at the tip that allows the probe to sit firmly on a male ECM or connector pin.
