What a Multimeter Is and How It Works
A multimeter is a diagnostic tool that measures voltage, resistance, and electrical flow. Since your vehicle uses electricity to power starters, alternators, batteries, sensors, and lighting systems, technicians use a multimeter to check each part. Because the tool connects to different points in the electrical system, it reveals whether components are getting the correct power. Therefore, multimeter testing helps technicians identify bad connections, weak batteries, failing alternators, and sensor issues — whether you’re commuting through Garland or driving toward Dallas.
