The LOADpro from Electronic Specialties is designed to find electrical faults, including high resistance resulting from corrosion, shorts to ground and open circuits. The LOADpro performs voltage-drop tests on 12-volt systems, st the push of a button, by applying a load of approximately 0.5 amps across the circuit. The device works with existing digital multi-meters and features SteadyPin probe tips. The SteadyPin tips have a small recess at the tip, allowing the probe to rest firmly on a male ECM or connector pin to assure correct readings. The LOADpro is available with an accompanying 200-page electrical trouble-shooting guide, Fundamental Electrical Troubleshooting
