A circuit tester for 12 to 24 V electrical systems that supplies power and ground to activate components such as cooling fans and relays. The integrated digital voltmeter captures min/max voltage readings to identify circuit performance issues, shorts, and bad grounds. For extended reach, the tester includes a 20-foot (6.1 m) jumper lead set and a 4 mm banana jack for connecting additional accessories.
