Application
When a component, like a blower motor, won’t power up, the following typically happens: the supply voltage is measured, 12V is seen, and an assumption is made that the blower motor is bad. But if the wiring is bad and the shop orders a new part, that new part won’t work either. Connecting LOADpro at the component's 12V connector and pressing the button will give you the answer. If the voltage drops, you don’t order that new part because it’s a wiring fault instead. This product and its built-in voltage drop test prevent part-swapping episodes and save time.
Origin
Voltage drop is the simplest way to find wiring faults. If a circuit is loaded and there is resistance in the form of corrosion or bad grounds, the voltage will drop. If the voltage doesn’t drop, the circuit is good. This test determines if the problem is with the car part or the wiring, and it does it in just a few seconds. This tool and a volt meter or digital multimeter are all you need, and doing voltage drops will make your customer a better tech.
Features and benefits
- This product finds wiring faults and does it quickly. Many wiring/connector faults are the result of corrosion, which is a form of resistance. Press the button and current will flow. If there is corrosion or bad grounds, the voltage will drop and you'll know wiring is the issue. It’s fast.
- LOADpro Test Leads 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.
Manufacturing/engineering specifications
LOADpro Dynamic Test Leads are 60" in length and work with any digital multimeter. The included volt meter has a 0-50V DC test range with 0.1V resolution.
