📓FREQUENTLY ASKED QUESTIONS

Q:  What do the numerical and LED indicators signify?

A: The Automotive Power Circuit Probe Tester has both digital numbers and LED indicators to help with automotive electrical testing:

1. Digital Display Numbers:

• Shows real-time battery voltage (typically 12V for cars, 24V for trucks)
• Voltage range: 6V to 24V for accurate battery health assessment
• Source voltage display: Always shows the connected battery's voltage, not the probed component's voltage
  

2. LED Indicator Meanings:

• Green LED: Indicates positive (+) power is present at the probe tip
• Red LED: Indicates negative (-) ground/polarity at the probe tip
• No display: Safety feature when connections are reversed (protects the tool)
  

The digital screen helps you monitor battery health while the colored LEDs quickly identify polarity and power presence during circuit testing.

Q: What's normal battery voltage?

A: For the Automotive Power Circuit Probe Tester, normal battery voltage is 12.6V for cars (12V systems) or 24V for trucks (24V systems) when fully charged and the engine is off. The digital display shows your battery's real-time voltage, while the green LED indicates positive power and the red LED indicates ground/negative polarity at the probe location.
