Why Need ItWith the GODIAG probe tester, you can test for continuity/polarity/voltage and ground signals/Short&Open Circuit. And most importantly, you can also use the Power Circuit Probe to check switches, relays and the on-off of diodes, fuses and circuits, activating electronic components. This probe tester can assist you in tracing problem wires and locating breaking points.
         
Quick Self-Test & Overload ProtectionBefore you test a circuit or component, the tester can perform a quick self-test to ensure your tool is in good condition. If overloaded, the 10-amp circuit breaker within the circuit probe tester will trip and automatically disconnect the protection circuit. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload and make the product more long-lasting.
         
Grounding Test & 20ft Long Test LeadThe electric probe circuit tester has a ground prompt device, if the LED indicator turns green and the buzzer sounds, it means the ground is good. If not, the LED remains red and does not beep. The Circuit Tester features a long 20-foot (6m) cable that allows you to test from the front to the rear of the vehicle (trucks, trailers, vessels, tractors and other vehicles that use DC circuits), so easy to check the whole electrical circuit system.
         
LED Indicator & BuzzerWhen the dc circuit tester touches the positive pole, the LED should be red and the 'beep' will become sharp; when it touches the negative pole, the LED should be GREEN and the beeping sound will become smooth, which can help you quickly identify the positive and negative polarity of the vehicle cable and plug.
         
Activate & Test ComponentsTo use component activation with a circuit tester, you typically connect the tester to the circuit and then use the tester's controls to activate or control specific components, such as relays, solenoids, or actuators. By allowing you to activate or control specific components in a circuit, you can help diagnose problems more quickly and accurately, and make repairs more efficiently.
