allsun EM287 Automotive Circuit Tester, 2-24V LED, 16.4 ft Cable

If you have a boat, at some point you'll need to make repairs yourself as the cost of marine repairs is high. Many issues onboard are pumps and motors that fail. Sometimes its the part and sometimes its an electrical connection. This tool easily helps you determine quickly which of these it is. The wire length is perfect for my application and I can see exactly how many volts my equipment is receiving.

It's well made, but it's a bit difficult to get used to because it shows a fixed voltage. But it's a matter of time.

This large circuit tester is designed for more demanding electrical testing tasks. It feels durable and performs well in heavier-duty diagnostic situations. The readings are consistent and easy to interpret. Overall, it’s a solid tool for more advanced automotive or electrical work.

Best electrical tool you can buy if you work on cars or trailers. Works great I use it all the time.

This tester works great for diagnosing auto electrical faults. Especially appreciated is the ability to inject + or - through the probe tip. The voltage readout is analog via a series of LEDs, a little difficult to read, but serves the purpose. The single front LED is not very bright but again, it serves the purpose ok. Overall, this is a very good value.

Mine already don't work... only used it a handful of times. However, the company reached out to me to resolve my problem and has since offered to replace it. So far I am very pleased with my experience... ...sent a new device in place of the defective unit. 5 star customer service

Enabled me to diagnose car power window. Window would not go up. Was able to use short jumper wire/ground to window motor and use this tool as power probe to actuate motor to ra it se window. Awaiting new master switch to complete repair. Best $20 spent in a tool!

But it functions well and is a great value. I am going to use the cable off my broken power probe.

Item arrived promptly and was exactly as described. I like the variety of options this particular tester offers although as advised in the instructions you need to ensure it’s in the correct mode before testing units to ensure you don’t cause a short in certain test modes. Overall I’m very happy with the purchase, the price and performance to date.

très prtaique facilité d'utilisation

Me llegó hace 2 días y el día de hoy quise probarlo y tratamos por media hora en varias partes y jamás encendió ningún foco incluso limpiamos la batería y nunca funcionó , mal producto

Très bonne pièce

Bon, il faut savoir ce qu'on fait et il faut apprendre à s'en servir, mais c'est un outil de mesure et de détection de panne redoutable !
