This tool is bloody good I hope you did get your money back out of it Dan

as a DIYer I’ve used it only a few times - with success

people keep comparing it to the power probe the reality is there’re two different tools my power probe four will show on the screen the condition of the fuel injectors whilst the motor is running

Each injector is 300 bucks so you’ve just paid for the power probe by changing one injector instead of all eight

it’s a completely different beast you need both of them to be honest…..!!!!!

The LoadPro is absolutely essential

The fact you can test the condition of the wiring in the harness is unreal

And when I do find problems nine times out of 10 it’s a connector somewhere that’s corroded

Excellent Dan…..!!!! You’re a very smart man…!!!

"One small step for man...One giant leap for mankind!"

thumbs up for Jamie's Cryin during fuel pump test

The best ❤

Very good tool you just press the bottom and  see the voltage drop.very good

The tips on the LP bother me because they have standard lead tips. I would use this more if the leads were banana plug so I could attach my pin connectors. This would free up my hands to press switches.

In all the videos illustrating this tool I always see to people working together. One fumbling the leads and one pressing the switches

i need to understand more and thanks

Is there a possibility that if you inject current to a circuit that potentially passes through an ECM that you could blow the ECM?

But what’s happening inside the positive “load” probe? Is there a lightbulb? A big resistor? What is providing load?

Great tool,I bought it many years ago,but still in the box, very stupid, any way  question when you  checking the coil side on the relay base, did you turned the key to on position? Please answer me,thank you  from ontario ca

Ghost voltage is not voltmeter open circuit voltage when the leads are out of circuit. What was shown in the video as described as ghost voltage is just called open circuit voltage, which is not really ghosting anything.

Ghost voltage is a relatively stable, expected and displayed value on a very high impedance DMM. The meter is reading a voltage value that makes perfect sense for the system being tested but is really just ghosting the reading through a high impedance coupling mechanism (usually capacitive), but not as high by an order of magnitude as compared to the DMM input impedance, which with some high end DMMs is extremely high (greater than 10 Mega Ohms).

What follows is a description of how you would see ghost voltage on a DMM:

1) Reading AC volts in a residential AC load center: If you use a high quality DMM for AC work, like Fluke 289 TRMS Industrial Logging Multimeter you could be looking at the output of a 120VAC branch circuit breaker to see if it is off, only to read 113VAC on the DMM display when the breaker has clearly tripped and the handle is in the off (tripped) position. The circuit is indeed de-energized and what you are reading is AC ghost voltage being coupled into the DMM on AC volts, and is very common for high impedance DMMs.

The voltage reading looks familiar but is really a ghost, an electrical artifact. Just like a ghost looks like a living person, but in reality, there is nothing real. A ghost reading is a lie.

It is so common a problem in AC industrial work that with the Fluke 289 there is an AC Volts special mode called Low Z AC Volts that reduces the voltmeter input impedance to around 3.2k Ohms, which will eliminate ghosting. If you look in the Fluke 289 operators manual for this mode it talks specifically about ghost voltage.



2) Reading DC volts in an automotive power feed circuit fuse block bolt in fuse near the battery positive terminal: When measuring DC Volts you can also have ghost voltage in an automotive application where you measure the output of a large current fuse relative to battery negative and it reads +12VDC. But, when a load on the circuit the fuse is powering is turned on (draws current to operate) it fails to operate.

What has happened is there is corrosion on this high current bolt down fuse where by it is acting like a very high impedance voltage source, but still at least 10x times less than input impedance of the DMM. To combat this it would also be helpful if the Fluke 289 had a Low Z DC Volts range, but since the Fluke 289 is designed for industrial AC work it does not. But, there is an easy fix, all you have to do is lower the input impedance of the DMM on DC Volts with a resistor at the meter across the voltmeter inputs. For power feeds on a 12V application 1000 Ohm should work well, and you will not be fooled by DC ghost voltage again, even on Halloween.

Going back in time, if we measure AC Volts with a Simpson 260-8 Analog VOM as opposed to a DMM, you will not be fooled by ghost voltage for residential AC work. The Simpson, when set up to read 120VAC will have an input impedance of about 600 Kilo Ohms as compared to the input impedance of some high end DMMs like the Fluke 289 at 10 Mega Ohms or higher.

hello
would you use the load pro to diagnose CANBUS wiring

Does this work on any voltage as being a forklift tech i often use 48 volts ?

hi this is frederick i will to paticipate in your
lesson how do i go about if

what about using this on computer circuits? could this cause damage to the computer ?

Porque no?  

dont know if your testing the ground to the emc

great video but I don't  understood  when testing  the fuel pump circuit, did you pressed  the bottom while  cranking the engine? please explain  thank you, cheers, saludos amigo

Porque no entiendo completamente el funcionamiento del circuito interno  de la herramienta. Es posible que tenga algun resistor con un valor muy exacto que se pone en serie con el voltimetro al presionar el interruptor y lo que se esta midiendo es la caida de voltaje, pero no puedo saber cual es el valor del resistor, puede ser 1, 10 u 100 ohmios.  De todas formas voy a experimentar en mi laboratorio para entender mejor y luego compro el Load Pro, porque aunque no me convence me inquieta.

No me convence.
