allsun EM285 Power Circuit Probe Tester, 6-24V Automotive Short Finder

TRACE SHORTS AND BAD GROUNDS: Start at the affected fuse circuit and follow suspected wiring through the harness. The LED indicator and audible overload alert help identify shorted sections and questionable ground connections. | CHECK POLARITY AND CONTINUITY: Red and green LEDs identify positive and negative polarity at a glance. Use the probe and auxiliary ground lead to check continuity on disconnected, de-energized wires and components. | POWER COMPATIBLE COMPONENTS: Apply positive or negative battery power to compatible lights, relays, solenoids, small motors and fans to help verify operation without repeatedly changing diagnostic tools. | 8A AUTO-RESET CIRCUIT BREAKER: The powered output disconnects when current exceeds 8A and normally resets after approximately 35 seconds. The jumper-lead configuration is not protected by the circuit breaker. | 624V DC WITH 16.4 FT REACH: Connect directly to the vehicle battery and reach rear lights, trailer connectors and distant wiring with the 5 m cable. Do not use on AC or apply power to sensitive electronic modules.
