A modern circuit tester with time tested durability. Quickly and safely tests high and low voltages (power and ground) on all vehicles, including computerized engine and body controls.

• Tests 6, 12, and 24 volt systems
• High impedance - current draw less than 18 milliamps to protect sensitive electronic sensors, microprocessors, electronic ignition components and air bags.
• Dual color LED indicates red for power (high) and green for ground (low)
• 6' heavy duty, 18 gage dual leads with large battery clips
• Leads can be attached regardless of polarity
• Includes Protect-A-Terminal® probe adapter to prevent damage to electrical connectors
• Can be used as a standard, single circuit tester.
• Instructions included.
