## Description

LOADpro Dynamic Test Leads with 200 Page Book Fundamental Electrical Troubleshooting

Review: Diagnostic Precision Heaven!!! - The ESI 181 Load Pro Dynamic Test Lead: is the Load Pro LEADS(180) with the: Fundamental Electrical Trouble Shooting BOOK (182) This instrument fits MOST Digital MultiMeters (DMM) {May not fit into all} The tool works on the premise of drop voltage, which CAN NOT be accomplished properly with traditional DMM leads! The results are absolutely not only easier , but moreover more concise and COMPLETE It has the ability to test the WHOLE circuit , not just from point to point segments There can ONLY be 3 results that occur: 1)OPEN 2) SHORT-TO-GROUND 3) HIGH-RESISTENCE The book will in detail explain and help you HOW to intrepid & determine the results! and more! Aside from also being able to determine if the fault is in the positive side or negative side of the wiring of the circuit You just plug them into your COM jacks: POS to POS and NEG to NEG , Then set it to Volts with auto being: DC Voltage It is important to understand: this tool should be used in a STATIC state: Vehicle ON , BUT NOT with the Engine turned over! Then place the POS lead to the POS side of the wiring of the circuit and the NEG lead into the NEG side of the same wiring circuit , PUSH the button, then read the results I would refer you to either the instructions or the 182 book on reading the results, as it is important you do this responsibly and properly, ..........yet it is very easy! The LOAD Pro pays for itself in a few short uses and to me is an exceptional awesome, better way to diagnose electrical faults (problems) IT also, can be used on boats, trailers, house devices for electrical trouble shooting! This tool is a diagnostic instrument....meaning I recommend you respect the tool and handle it carefully, as you can damage it by dropping it or smacking it against something, or getting it wet or dirty! Even though I have had a basic understanding of electrical uses , the book is great it can be read all the way through, then used as a quick reference for MOST all electrical subjects, including concept, spelled out explanations, and some illustrations. The BOOK works on the premise of teaching and also easy referencing , which was created by an instructor: Dan Sullivan (the author of the book) 20 plus experience in instructional training in the trucking industry. He designed it to be presented in an easy understanding , non-complicated way! I am so glad I opted to get the 181 package with the book I would strongly recommend BOTH the Leads & the book for any & everybody, who is willing to learn fundamentals of electrical subjects, follow directions, and use the tool in a responsible respective manner. The ONLY thing I would pick at is that this tool does NOT have a case to protect it (or IF you have no room or case with you multimeter) I am looking at LowePro camera cases to store it in currently, that have padding. In my opinion, this tool was created by genius! IF you own it and understand how to fully use it, you will realize why I feel this way. In my experience, this is one of the absolutely GREATEST electrical tools one avid DIYer could own.PERIOD! desertcart is the Best place to get Electronic Specialties Inc. instruments.

Review: Hands Down one of the best electrical diagnostic tools for your tool box - I work in a professional shop environment and being the new guy, all of the electrical diag tickets got passed down to me because sh*t rolls down hill. I struggled through the diag jobs. I ended up seeing the LoadPro in a tool truck flyer which introduced me to the voltage drop testing concept. I bought the LoadPro and started studying voltage drop while waiting on the tool. The new diagnostic training combined with the LoadPro was a huge "level up" moment for me as a new technician. It's an excellent diagnostic tool and will speed up the diag process. The book itself is a great resource and I personally am a fan of physical books to keep around for quick reference. The 181 Kit would be an excellent choice for beginners, although I'm sure even experienced technicians will benefit from refreshers or learning knew concepts.

## Features

- Finds the problems like high corrosive resistance, shorts to ground, open circuits quickly
- By loading the circuit, LOADpro makes a voltage drop test "on the fly", just press the switch and the test results can not lie
- Kit includes 200 pages of hand written, hand drawn electrical troubleshooting tips and procedures
- LOADpro test leads work with almost any digital multimeter
- Also features steadypin probe tips, instead of a pointed probe

### ⭐⭐⭐⭐⭐ Your multimeter will lie to you!!! You NEED this unit
*by J***. on August 31, 2022*

I'm a heavy equipment mechanic. I think every mechanic hates chasing electrical problems.....is it a chafed wire, bad connector pin, bad relay, bad ground, combination of everything?? A friend of mine told me about this........I've always used a light bulb to apply a load. I got this on a Saturday, Monday morning I was called out to look at a hydraulic on a dozer..........while your there can you look at the AC?? The AC system has 2 fans on condenser on roof, with 2 relays.....1 for each fan, and then a connector then goes into cab. One fan was good, another bad. Using multimeter, it was showing I had voltage going to both fans.........push the button and apply load......the voltage disappeared. Using just the multimeter with Load Pro you would think you had voltage and it was all good. Popped down to fuse panel.........one fuse was blown, the other was good. The blown fuse was an EZ ID fuse......the kind that has an LED light in it to show when the fuse was blown. Thats where the phantom voltage was coming from..........push the button on the LoadPro and voltage went away. The old way would have taken ALOT longer. I climbed off the roof of the dozer yelling "YEEEESSSS!!! THIS IS AWESOME!!" Plus it was 95F, sun baking, and my knees were getting cooked on the metal roof............THIS THING IS SO WORTH IT. According to manufacturer.......this will handle 12v-28.5V so its good for 24V systems. The 12V version applies a 50 ohm load when the button is pushed. The book it comes with is very well written and would be a great learning tool and refresher.
