This is a great tester to find bad wiring and shorts fast. You can also test sensors and other electrical components in your engine.

This is a great tool! It does not come with a very well written instruction/user manual but look up videos on you tube on how to properly use every function.

Una basura. lo use solo 3 veces y se daño. el periodo de devolucin en Amazon ya habia finalizado y cuando me comunique con el soporte tecnico para comentarles la falla me contestaron que efectivamente se daño el chip integrado y que no podian hacer nada al respecto, ignorando el año de garantia que tiene dicho producto ( lo informa en el manual de usuario). La respuesta que me dieros es que "debia comprar una nueva". En definitiva tire mi dinero a la basura. NUNCA MAS COMPRARE ALGO DE LA FIRMA GODIAG.

I’ve been really impressed with the GODIAG Circuit Tester. Having used other name-brand testers that cost twice as much, I can confidently say this tester offers the same results with even more features. The relay tester is particularly useful when troubleshooting automotive electrical systems, and the harness for injector testing is another huge advantage.So far, it hasn’t let me down, and it came well-packaged, which was a nice touch. I’m not a professional mechanic, but I spend a lot of time working on vehicles, and this tool has been a great addition to my kit. For the price, it’s hard to beat the value this tester provides.

Über viele Jahre verwende ich ein amerikanisches Produkt damit war ich auch sehr zufrieden, das oben genannte Gerät ist aber wesentlich besser effizienter und gibt ein schönes Handgefühl. Für das Prüfen von solonoide und Relais benötige ich es nicht, da habe ich anderes Werkzeug.jedoch für einfache Diagnose finde ich das Gerät schon sehr vollkommen.

Didn’t realize how great this product was until I had an issue with some clearance lights on my shuttle bus. I didn’t know if there was an issue on the positive or negative side. After using this I found that I had ground but it was the positive side where the issue was (sound of ground was given, but positive side gave no auditable sound). I added the power by device and the lights lit up. Now, I had to find where the issue was with my positive and where I believe a good change should be on device. I wanted to check for continuity to make sure there was no break in the line, however the audio sound for positive is the same sound given for continuity. At first I was like, great…found other end of line….but it turns out it was just a disconnected (not used) positive power line. I found a second one like this too. It would have been helpful if the continuity sound was different than the other two sounds (positive and negative sounds). One thing I would get though to add to this awesome tool….an extra long cable (with large gator clips) to be able to go anywhere on your vehicle…especially if you have a large vehicle like my shuttle bus!!
