LOADpro finds these problems FAST
High Corrosive Resistance
Shorts to Ground
LOADpro Test Leads load the circuit to see if current can flow.
By loading the circuit, LOADpro makes a voltage drop test “on the fly”.
Just press the switch – the test results can not lie.
Use LOADpro w/your DMM and follow our test method – you will find wiring faults quicker.
LOADpro Test Leads feature SteadyPin Probe Tips, which allows the probe to sit firmly on a male ECM or connector pin.
LOADpro are OEM approved – finds corroded circuits fast!
Steady Pin Probe Tip
LoadPro Dynamic Test Leads feature Steady Pin Probe Tips, perfect for back probing ECM / ECU and component connector pins.
Insulated Banana Plug Adapters
The industry standard for multimeter connections, The LoadPro will connect directly to 90% of Multimeters on the market.

The process is very simple – just read voltage. It’s that easy, really. If a vehicle component is inoperable, just unplug the connector. Read voltage at the connector. Do you see 12 volts? If yes, press the LOADpro switch – if the voltage remains, the wiring is good – go on to something else. If the voltage drops – the circuit has high resistance… IE.- corroded wiring or connections. If you see no voltage initially, you have an open or short to ground. 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. Traditional pointed probes fail to give an effective connection and creates difficulties in completing manufacturer specific voltmeter tests. We recommend replacing your existing test leads with LOADpro and leave them in place.

Loadpro Voltage Drop Testing
I’m at the end of a epic back probing exercise and on the phone to my local parts store, I realize I’m about to make a stupid mistake, I have power and earth, but no component operation. Its always going to be the expensive part when you get caught out. Measuring voltage and performing Dynamic Load Tests is the easiest way to confidently and systematically rule out circuit faults. Measuring resistance requires you to disconnect circuits and can affect diagnostic productivity and accuracy. With Dynamic Load Tests you can’t disconnect anything because the test wont work. Meaning you can perform accurate tests on connected circuits.
Using the voltage (V DC/AC) setting on your multimeter is the most time efficient and accurate way to diagnose circuit faults.
Voltage Drop Testing
Open circuits will be displayed as ghost voltage (appears as a 0.XX voltage fluctuating up and down). Ghost voltage means there is no electrical connection between the power supply and the earth.
Voltage Drop Testing Short Circuit
Short circuits will be displayed as Zero volts (appears as a 0.00 volts). Zero volts means you have a short to earth, i.e. Something copper touching something steel.
Reading system voltage means you can rule out 2 of the possible 3 faults. Opens , Shorts.
Electronic Specialities Voltage Drop Testing with Load Pro
Performing a Dynamic Load Test will allow you to rule out any abnormal circuit resistance, usually in the form of a faulty connector or wiring. Because Multimeters are so sensitive, they will read system voltage with resistance in the circuit. Performing a Dynamic Load Test allows you to rule in or out the 3rd of the only 3 possible faults. Factually solidifying your diagnosis.
Multimeter LEads Electronic Specialities
Imagine you have a wire with all except one thin strand of copper broken, Your multimeter will read system voltage and a test light will glow, however trying to run a cooling off that is a never going to happen. Potential Thief !
Dynamic Load Testing
Electronic Specialities Dynamic Load Testing
By moving the negative probe to the chassis earth and reading system voltage under load we are able to eliminate the potential loss out of the negative side of the circuit. Additionally, by moving the positive probe to the fuse and reading system voltage under load, we can infer that the resistive fault is in the section of wiring between the fuse and connector 2.
Voltage Drop Testing Load
This test is able to be performed by applying a 0.5 amp load in the circuit. Loading the circuit will make any voltage potential loss infallibly visible.
