Red/Green Polarity Indicator - Identifies positive, negative or open circuits. The RED Indicator lights when the Probe Tip is contacting a positive circuit. The GREEN Indicator lights when the Probe Tip is contacting a negative circuit. LCD Display - Displays test results. Power Switch �... -
Page 7: General Description
3.4 General Description The tool is designed to reduce diagnostic time on all 6 to 30- volt vehicle electrical systems. After a simple hook-up of the tool to the vehicle's battery, you can: • Determine at a glance if a circuit is positive, negative, or open without having to reconnect clips from one battery pole to another. -
Page 9: Work Mode
When the circuit breaker is tripped, the LCD will display as below (Figure 2). All other functions of the tool are still active, which means you can still probe a circuit and observe the voltage reading. When the circuit breaker is tripped, the tool will NOT be able to conduct battery current to the tip even when the power switch is pressed. - Page 10 Figure 4 Resistance With the tool in resistance mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead (Figure 5). 600Q Figure 5 Diode The d iod e work mod e is to test the polarity of a PN junction diode (Figure 6).

Figure 8 4.2 Continuity Testing With the tool in Resistance mode, using the probe tip with chassis ground or the auxiliary ground lead, continuity can be tested on wires and components attached or disconnected fr o m the vehicle's electrical system. With the probe tip contacting a good ground, the LCD will indicate "0.0 and green LED will be on. - Page 13 Figure 9 If the probe is not contacting a good ground the LCD indicates the res is tance value (Figure 10). 600Q Figure 10 If the resistance value is greater than lOOkQ, the LCD will show "OL". -11 -...

Continuity can also be tested by powering up the connection using the power switch. If the circuit breaker trips you know that you have a good low resistance connection. NOTE: You can use the probe tip to pierce the insulation on a wire. -
Page 15: Activating Components
4.4 Activating Components With the tool in DC Voltage mode, by using the probe tip with the auxiliary ground lead, components can be activated, thereby testing their functions. Connec t the auxiliary ground lead to the negative terminal or ground side of the component being tested. -

If the green LED went off at that instant or if the circuit breaker tripped, the tool has been overloaded. This could happen for the following reasons: • The contact you are probing is a direct ground or negative voltage. •... - Page 17 q uickly depress and release the power switch forward. If the green LED went out and the red LED came on, you may proceed with further activation. (Figure 14) If the green LED went off at that instant or if the circuit breaker tripped, the tool has been overloaded. This could happen for the following reasons: •...

4.8 Checking for Bad Ground Contacts Probe the suspec ted ground wire or c ontac t with the probe tip. Observe the green LED. Depress the power switch forward then release. If the green LED went out and the red LED came on, a beep will sound, this is not a true ground. -
Page 20: Test Tool Know-How
If the circuit you are testing is not within a 0.4 volt (plus or minus) of supply voltage, you will see the voltage reading on the LCD but you will not hear a tone or see a red or green LED. This tells you either you have a voltage drop in excess of 0.4 volts from battery voltage or you are probing a circuit that has an increase of a 0.4 volts or more over battery voltage. - Page 21 -19-...
