allsun EM415Pro Automotive Circuit Tracer, DC 6-42V Wire Tracker Tool

Bought this specifically to locate a break in a boundary wire for a Gardena robot mower (made by Husqvarna). I wasted hours trying to find it without a tool, but within 10 minutes of hooking this thing up, found the source of the break nearly 100 feet away from the loop. The signal had grown quite weak by then, but was still detectable if the sensor was placed next to the wire. I’m sure this thing will come in handy for future repairs to the boundary wire, as well as wiring issues on vehicles. It did include a pair of 9V batteries, but I think one of them died within a few minutes of use, so probably best to hand a new set on hand.

This is a good tool that is inexpensive and will pay for itself time and time again, chasing down open and short circuits just from the time you'll save as a flat-rate technician. I ordered it on Saturday, got it on Sunday, and used it on Monday. I was using another brand of short/open finder that you can buy off the tool truck for quite a few more bucks than this costs, and I've opened up the wire harness in four spots with false readings and found nothing. I spent a considerable amount of time trying to find an open circuit that could've been anywhere from the front PDC all the way to the spare tire where the Tire Pressure Monitor Module is, but decided to move onto something else because I had several things to do and come back to it later. I ordered this tool and used it Monday. I hooked it up to my circuit, and within 2 minutes I had located where the open was in the harness. I opened it up, and sure enough, that was where it was. I repaired the wire, and the Jeep was fixed. This tool shocked me, especially for how much I paid for it compared to other tools.

Like many others, used this to try to find a short in an engine bay. First time using such a device and I have no idea if I used it correctly. Meanwhile, a power probe clone tool later confirmed there was no short and crank-no-start mystery was resolved (the culprit was a dead PCM). While I didn't have "success" with this tool, I know many people swear by them when there's an actual short to be found so I'll be keeping this on hand.

Don't work like the way it shows in the videos

For first-time users, the directions are worthless. They lack the courtesy of telling you the sender and receiver are already have batteries in place, but they are wrapped in a clear wrap. This part of the setup is not a big deal, but it just goes to show you they maybe make a great product, but have no clue about making their tool user-friendly. This is a whole new world for me and others who have always done the same thing., but in the old fashion way that this tool supposedly does. For the first-time user, there would be a steep learning curve, plus the directions are terrible, bad, bad, bad. My review is based on first-hand information, but I never was able to use the tool because of the failure of the tone/buzzer. The directions are what they are, short on descriptions... They should have a warning. "for Professionals only who have experience with this tool"... Good luck,...

Tried one of these to help find a short in the wiring and it made it were easy worked great. Need to have a basic knowledge of electric wiring.

The sensitivity of this thing is its main downfall. Have a melted/fried wire somewhere and it's now connected/shorted to the ground; which means just about everywhere in the vehicle is a continuation of said wire... the probe ends up giving it's tone anywhere inside the vehicle - as it'll pick up the tone from feet away - and you're always within a foot or two of something metal in a car. It's practically useless - unless you have a clean cut wire that's not shorting to anything (how often does that happen?). In this case I do think it's a "you get what you pay for" - I imagine the 300 dollar+ versions of this tool have the sensitivity dialed in.

Tiene un sonido estraño cuando preciono el botón donde dose TEST se escucha que la speaker esta dañada. It has a strange sound when I press the button where dose TEST you hear that the speaker is damaged.

Ya lo probé después de varios meses que lo adquirí y me punciono perfecto lo recomiendo me ayudó a resolver una falla

Just delivered. Connected batteries. Switched both on. Shows by tone if there is a break in the wire. Comtinuity works as well,shows if all is well in that particular wire. Thank you.

Actuellement en pleine rénovation d’appartement pour retrouver les câbles à quoi il corresponde très pratique

I needed to figure out where the pre-wired solar panel wires were routed on my RV. This tool did the trick (open circuit test) and I was able to trace the wire up the wall and across the roof to the back corner. It did not work through the tin siding (no signal) but worked great from inside.

Fait très bien son boulot
