Quick User Guide & Troubleshooting

Safety Warning: Do not use with electronic ignition systems except as specified by standard automotive testing guidelines. Always ensure the ground connection is secure before testing.

• Step 1: Connect to Ground – Attach the heavy-duty alligator clip securely to the vehicle's chassis or any reliable ground source.
• Step 2: Check for Power (Live Wires) – Probe the wire or terminal. If power is present, the internal LED will instantly glow and display the current voltage.
• Step 3: Locate Broken Wires – Trace along the wire while probing. The exact point where the display turns off indicates where the circuit is broken.
• Step 4: Test Fuses Fast – Simply touch the probe tip to the terminal after the fuse. A glowing indicator confirms your fuse is intact and functioning.
• Step 5: Diagnose Light Sockets – Connect the alligator clip to a ground source and touch the probe directly to the tongue at the base of the brake or back-up light shell.
