The Power Probe 3 and Power Probe 4 are both diagnostic tools used for automotive electrical testing, but they have some differences. The Power Probe 3 is a more basic model that offers functions like voltage and polarity testing, continuity testing, and activating components with a momentary or latching power switch. The Power Probe 4, on the other hand, offers advanced features such as a color LCD screen, a built-in voltmeter with peak-to-peak mode, and additional diagnostic capabilities like fuel injector testing, making it more versatile for complex diagnostics.
