BOSSCOMM electric car tester lets you activate and test common automotive components: blower motors, power window motors, wipers, defrosters, headlights, radiator fans, injectors, relays, and more. No more swapping out perfectly good parts by mistake—the P180 car electrical tester pinpoints the fault on the spot.

【⛽Fuel Injector Testing & Cleaning | Save $200+/Year on Shop Fees】 Notice your car’s fuel efficiency dropping sharply or struggling to accelerate? Mechanics charge $200+ for injector cleaning—but you can do it like a pro at home with the BOSSCOMM P180.This automotive power circuit probe tester sends targeted pulse signals to diagnose clogged injectors or poor atomization. It also has 4 cleaning modes for different contamination levels and vehicle needs. Perform professional injector maintenance, slash repair costs, and keep your engine running at peak performance— all from your garage!

【🔋12V Battery Test + Dual Power Supply | Save $40 on a Standalone Tester】 Is your battery charging properly? How long will your battery last? Our built-in battery test supports cranking, charging and overload tests, detecting hidden battery health issues before they leave you stranded on the road. Simply start your vehicle first, then connect the alligator clips to your car battery to begin testing. Supports both cigarette lighter plug-and-play and direct battery connection.

【💡Overload Protection + Dual LED Lights + 40FT Total Cables | Safe & Convenient】 Built-in resettable circuit breaker protection automatically shuts down the tester during overload or short-circuit conditions and triggers a buzzer alert—keeping you and your vehicle 100% safe. Dual LED lights on the probe tip illuminate dark areas like engine bays or undercarriages (no separate flashlight needed!). With 20FT + 20FT extended cables, you can walk freely from the front to the back of your car, truck, or tractor—eliminating distance limits and making it easy to test every hard-to-reach corner without struggling with tangled wires!

【🎯Intuitive Polarity & Continuity Test | Fast, Reliable Feedback】 The P180 automotive probe circuit tester provides instant polarity and continuity verification with dual cues: a red LED light and high-pitched beep for positive terminals, a green LED light and low-pitched tone for negative terminals, and no indication for open circuits. With ±0.8V sensitivity, it ensures accurate judgments even in complex wiring environments, making quick work of circuit checks without disconnecting wires or guessing results.
