one hell of a tool .i have been waiting 30 years for this tool

Highly recommended solid construction and the book is very helpful if it gets you out of strife once a year..... well worth it.

Warning- long read. I received this tool for a christmas gift. Prior to owning i used light bulb method to load circuit. This is much cleaner/easier. We all perform voltage drop tests. Probably more so on euro cars than others even though principal of wiring is same no matter whose emblem is on the car. The load pro has been out for while. But it doesnt get the fan fare it probably deserves because creater comes off as being a douche to most people. Personally, he doesnt bug me. But some guys get butt hurt over stuff he says. Mechanics should have thick skin from all ball busting that goes on in a shop so i dunno... Tool is basically set of leads that plug into multimeter. Lets you voltage drop circuit. After i got it, i did research on it and see people trying compare it to power probe. That is a bad comparison. Imo, they are two different animals. Each serve purpose, but to say they are same or even similar is wrong. Load pro would be better compared it to a homemade head light bulb wired inline for load testing than a power probe. Havent really had much use for it electrical diag wise up until month ago. In last week i have used it on 4 cars and im pretty happy with it. It has cut down on diag time and makes voltage drop testing quick/easy. For that alone worth the $60 it costs with wiring book. You can buy it without book for less, but book is worth the extra money for reference manual in box if nothing else. I primarily work on euro cars. I have co workers on Asian. Rare occasion we will see a domestic. Today was a domestic day. example of it in action from today- Co worker had this ticket and was getting no where. Had deer in headlights look. i jumped on it with him after buttoning up car i was working on. Maybe had 20 mins into it tops to diag/fix. Prior to me jumping in he had easy 2 hrs in it going no where. 01 chevy 2500 8.1l truck towed in no start. Check fuel/spark, no spark. Had crank signal. Pull up wiring diagram shows all 8 coils common ground that is mounted side of block. Check for power/ground at coil wiring using test leads probing grnd/12v pins on harness. Nothing. Put ground lead to battery, reads 12v power. Push button to voltage drop test- v stayed- power side is good. Continuity test to ground showed continuity. This is where co worker got burned. He ASSumed continuity = good. For hell of it i checked resistance and was on high side for my liking. Cant recall amount off hand though. Used loadpro to voltage drop ground circuit. Dropped from 12.6v to 7v. voltage drop 5v on ground side- not good. To explain it to coworker whom i was showing how to check/test- i back probed ground at coil harness on valve cover and overlayed to battery gnd and truck ran. Minute i removed overlay from battery gnd it died. At this point, i was left with following- either ground spot at block is bad, or wire broke in harness. If its solid at bolted ground spot, then ground is broke in harness needs overlay because not cutting open harness looking for broke ground. In the end, found ground terminal at block to look ok. Yet when removed it was corroded about inch up that when i went to twist wire to look at backside of ring terminal it broke. Wire was long enough that new ring terminal fixed issue. Voltage dropped it after the fix all good. In short, if you do voltage drop testing, this is an easy to use tool worthy of being in your tool box.

Works awesome. I'm a diesel technician and it has cut down my electrical diagnosis by 50 percent. The book is also very well written.

Very simple and informative book and the load pro leads are a real time saver

Very functional. Manual a must.(included) Worth the cost

Very helpful book and tool.

Awesome tool and even more awesome text book!!

The book alone with out the loadpro is worth every penny I paid and some. If your new to automotive electrical systems or just want a simpler way of understanding it then this book is a must have.

The book is well written, easy to understand, and a perfect reference to have on hand. Dan Sullivan breaks the mold when it comes to electrical diagnostics. I learned more from this book about electrical diagnostics than I did in tech school and other diagnostic courses I have attended. The LOADpro leads are a must have! They completely expedite troubleshooting procedures and alleviate spending money on misdiagnoses. Whether you are working on heavy diesel, automotive, or just troubleshooting at home, these leads will save you time and money. My entire shop now has a set for every tech. They are designed with technicians in mind and do not come with an inflated price tag like normal tools from tool trucks. Dan Sullivan even made videos on youtube explaining how to benefit from these leads.

Great

This is a good tool. My VOM did not find the wiring problem, this tool showed the problem, which was a connection that still existed, but high resistance that could not be seen on a VOM on the volt or ohm scales

Product is worth its weight in gold. Planning to purchase 1 or 2 more.

Handy

Mr. Sullivan 34;Dan34; has put to text a voluminous collection of teaching for mechanic/technicians worldwide with this book. His style of putting information into ones memory is unmatched imho.

Clearly laid out principles and easy to understand. Totally satisfied and empowered to work with these principles with or without the LOADPro.

This book and its format works great for me. I admire Dan Sullivan's professionalism. Thanks, Al Amigo

Great tool. Once you understand how this works it will save you so much time diagnosing electrical issues. Saved my butt a few times now. A must for any tech. Some dingdong in another review said wishes he could change batteries in it. Lol. There are no batteries in it. It has a resistor. Its a small load for the circuit. It doesnt power up the circuit. Learn how to use it and it will be a great tool for you.

Good tool

Awesome.
