AUTOOL BT160 Automotive Circuit Tester Circuit Checker

The AUTOOL BT160 automotive circuit tester helps reduce diagnostic time when checking 6-24V DC vehicle electrical systems. After connecting the red and black clips to the vehicle battery, technicians can probe circuits, identify positive, negative, or open states with LED feedback, activate selected components through the power switch, check bad ground contacts, and follow short circuits more efficiently. BT160 is designed for automotive 6-24V DC circuits. Review the power limitation, spark warning, inspection checks, probe safety, and overload behavior before testing. Compare BT160 with other AUTOOL circuit tester models before choosing voltage range, screen display, cable length, measurement functions, and advanced diagnostic modes. BT160 focuses on fast visual circuit checks, polarity recognition, open circuit and continuity testing, diode status checking, grounding confirmation, short circuit following, and overload protection. BT160 uses a simple probe-style layout with battery clips, auxiliary ground clamp, LED indicator, power switch, 4m lead length, and 10A overload protection for 6-24V DC automotive systems. Key features • 9-30V Support: The stated 9-30V DC range suits common 12V cars and 24V heavy-truck electrical checks. • Continuity Check: Continuity testing helps trace open, closed, virtual, and real circuits during electrical diagnosis. • Polarity Test: Positive and negative polarity indication speeds up wiring checks when probing unknown circuits. • Product: AUTOOL BT160 Automotive Electric System Tester • Operation Voltage: 6-24V DC • Overload Protection: 10A
