【Extended Voltage Range & Overload Protection】

It is suitable for diagnosis of all 6V to 24V automotive electrical systems and can work well on cars, trucks, boats, trailers, and motorcycles.    The tester also has an overload protection device, When the current exceeds 8A, the circuit breaker inside the device will automatically trip and give out a buzzer prompt.

【Polarity Test & Continuity Test】

The power circuit probe tester is made of insulating material and high-quality stainless steel tip, which can help you quickly identify the positive and negative polarity of the vehicle cable and plug.

When the dc circuit tester touches the positive pole, the LED should be RED; when it touches the negative pole, the LED should be GREEN.  

【13FT Long Extension Cable&Buzzer Warning&Highly Sensitive Probe&Clips with Strong Bite】

The cable length of the circuit tracer is about 4m(157.5inch) which allows you access and test any electrical system easily.  

Test light adopts advanced high sensitivity probe, which provides you quick and accurate detection.   

Its clips with strong bite force which not easy to fall off, providing you better experience.

【Tracking and Locating Short Circuit】

The power circuit probe tester uses advanced high-sensitivity probes to provide you with fast and accurate detection.        Using this automotive test light can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point.

【Automatic Reset Test Light】

When the circuit breaker trip is detected, the power circuit probe tester will sound a prompt to remind you that there is a short circuit problem.    Then it will automatically reset within 3 to 5 seconds(the prompt sound will automatically turn off), so you can retest or go to test other places.

【Versatile Testing Capabilities】

The power circuitprobe tester is a multi-functional tool designed for a widerange of automotive electrical components, includingswitches, relays, and fuses, making it suitable for variouselectrical systems.

All-Sun EM285 probe tester is an Electrical Tester for Reducing Diagnostic Time in Automotive Electrical Systems. The car circuit tester has short-circuit protection and can test for bad ground contacts instantly.

EM285 car circuit tester tool cable length is about 16ft Makes Your Testing Easily. EM285 Automotive electric system 6-24V DC tools is a Comprehensive test kit. After a simple hook-up of the unit to the vehicle's battery, automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward.

Automotive electric system is test for continuity. Test for polarity of a voltage. Check switches, relays and the on-off of diodes, fuses and circuits . Test for polarity of electric cables and plugs. Track and locate short circuits. Test for bad ground contacts.
