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.
