This circuit tester also supplies Battery Voltage or Ground to activate components. The housing is sleek and feels great in your hand. This powerful time-saver tool is perfect for every level of technician. Features : Ability to Power Up Components ● Audible Tones Voltmeter ● 12 - 24 Volt Range 20 ft. Power Cable ● Bad Ground Indicator Continuity Tester ● Short Circuit Indicator Relay and Component Tester While the PP3 is in Power Probe Mode. Contact the probe tip to a NEGATIVE circuit. The green negative sign “-” LED will light. If the audio feature is turned on, a low pitched tone will sound. While the PP3 is in Power Probe Mode, contact the probe tip to a POSITIVE circuit. The red positive sign “+” LED will light and the voltage reading of the circuit will be indicated on the LCD display. If the audio feature is turned on, a high pitched tone will sound. 1. Connect the PP3 to a good battery. 2. Clip the auxiliary ground clip to the trailer ground. 3. Probe the contacts at the jack and then apply voltage to them. This lets you check the func-tion and orientation of the connector and trailer lights. If the circuit breaker tripped, that con-tact is likely a ground. Reset the circuit breaker by letting it cool down (15 sec.) and depress-ing the reset button until in clicks into place.
