Quickly locate and resolve electrical faults in 12-volt and 24-volt vehicle platforms with the Autel PS100 PowerScan automotive circuit tester. Engineered for professional diagnostics, the unit performs four measurement modes: DC voltage with 0.1V resolution, AC voltage tracking with frequency and duty cycle analysis, resistance testing from probe tip to auxiliary ground, and Tone On/Off for accurate wire tracing in enclosed spaces.
Move past passive multimeter readings by directly commanding system behavior. Generate activation signals to verify full operation of dome lights, body control relays, cabin blower motors, cooling fans, and trailer harness outputs without compromising original wiring integrity. Rapid polarity detection identifies positive feeds, negative grounds, open circuits, and confirmed continuity across complex looms.
Persistent underhood and cargo bay inspections demand physical reach and unambiguous feedback. Extend your probe depth using the integrated 20-foot cord connected to an additional 20-foot lead, safely navigating transmission tunnels, firewall penetrations, and dash clusters. The hardened stainless-steel needle tip secures contact on damaged terminals, while live measurements render on a backlit LCD alongside color-coded LEDs and instant audio cues—accelerating fault isolation on every service call.
