Performance Tool Digital Automotive Multimeter

Tracking down an electrical gremlin in your car is a lot easier when you have a meter that speaks automotive. The Performance Tool W2972 is a 5-function digital multimeter built for car and truck electrical work, covering AC and DC voltage, DC current, resistance, and diode testing. What separates it from a basic hardware-store meter are the tach and dwell settings, which let you check ignition timing and dwell angle without needing a separate tester.

The extra-large LCD display is easy to read even in a dim engine bay, and the meter includes automatic reverse polarity indication so you know right away if your probes are on the wrong terminals. Overload protection on all ranges helps prevent damage if you accidentally select the wrong function. The UL-listed test probes measure 42 inches long, which gives you enough reach to probe connectors deep in the engine compartment without having to stretch or use extensions.

Whether you are chasing a parasitic draw, testing an alternator output, or checking resistance on a sensor, this meter covers the basics that come up most often in automotive diagnostics.
