4.3 Polarity Test (FIG.2)

Contacting the probe tip ? to a positive (+) circuit will light the test indicator ? RED.

Contacting the probe tip ? to a negative (-) circuit will light the test indicator ? GREEN.

Contacting the probe tip ? to an open circuit does not turn on the test indicator ?.

Visual Description (FIG.2): Diagram illustrates polarity testing. One shows the probe tip touching a positive (+) terminal, lighting the indicator red. Another shows the probe tip touching a negative (-) terminal, lighting the indicator green. A third shows the probe tip not touching anything, with the indicator off.

4.4 Continuity Test (FIG.3)

NOTE: ? DO NOT press the rock switch ?️.

By using the probe tip ? together with the auxiliary ground lead ?, continuity can be tested on wires and components which are disconnected from the vehicle's electrical system.

When continuity is present, the test indicator ? will light GREEN.

Visual Description (FIG.3): Diagram shows continuity testing. The probe tip and auxiliary ground lead are connected to a disconnected wire or component. The test indicator is shown as green.

4.5 Activating Components Out of the Vehicle's Electrical System (FIG.4)

By using the probe tip ? together with the auxiliary ground lead ?, components can be activated, thereby testing their function.

Connect the auxiliary ground lead ? clip to the negative ➖ terminal of the component to be tested. Contact the probe ? to the positive ➕ terminal of the component; the test indicator ? should light GREEN indicating continuity through the component.

Whilst watching the green test indicator ?, quickly press and release the rock switch's front part ("-"). If the green test indicator ? changed instantly from GREEN to RED, you may proceed with further activation. If the green test indicator ? went off at that instant, the unit has been overloaded. This could happen for the following reasons:

• a. The contact of the tip is a direct ground or negative voltage.
• b. The component is short-circuited.
• c. The component is a high amperage component (i.e. starter motor ⚙️).

Visual Description (FIG.4): Diagram illustrating activating components with positive voltage. The probe tip is connected to the positive terminal of a component (e.g., a motor), and the auxiliary ground lead is connected to the negative terminal of the component. The rock switch is shown being pressed.

4.6 Testing Trailer Lamps and Connections (FIG.5)

1. Connect the unit to a good battery.
2. Clip the clip of the auxiliary ground lead ? to the trailer ground.
3. Probe the contacts at the jack while pressing the rock switch's front part ("-").
4. This lets you check the operation and orientation of the trailer lamps ?.

4.7 Activating Electrical Components

4.7.1 Activating Components with Positive(+) Voltage (FIG.6)

Contact the probe tip ? to the positive ➕ terminal of the component; the test indicator ? should light GREEN.

Whilst monitoring the green indicator ?, quickly press and release the rock switch's front part ("-"). If the green indicator ? changed instantly from GREEN to RED, proceed with further activation. If the green indicator ? went off at that instant, the unit has been overloaded. This could happen for the following reasons:

• 1. The tip's contact is a direct ground.
• 2. The component is short-circuited.
• 3. The component is a high current component (i.e. starter motor ⚙️).

WARNING! ⚠️ Haphazardly applying voltage to certain circuits can cause damage to a vehicle's electronic components. Therefore, it is strongly advised to use the correct schematic and diagnosing procedure while performing test.

Visual Description (FIG.6): Diagram showing activating components with positive voltage. Similar to Fig. 4, showing the probe tip on a component's positive terminal and the auxiliary ground lead on its negative terminal, with the rock switch activated.

4.7.2 Activating Components with Negative (-) Voltage (FIG.7)

Contact the probe tip ? to the negative ➖ terminal of the component; the test indicator ? should light RED.

Whilst monitoring the red test indicator ?, quickly press and release the rock switch's rear part ("="). If the red test indicator ? changed instantly from RED to GREEN, proceed with further activation. If the test indicator ? went off at that instant, the unit has been overloaded. This could have happened for the following reasons:

• 1. The tip's contact is a direct positive voltage.
• 2. The component is short-circuited.
• 3. The component is a high amperage component (i.e. starter motor ⚙️).

WARNING! ⚠️ With this function a vehicle's fuse ?️ can be blown or tripped if grounding the contact in series with it.

4.9 Checking for Bad Ground Contacts (FIG.9)

1. Probe the suspected ground wire or contact with the probe tip ?.
2. Observe the green test indicator ?. Press the rock switch's front part ("-") then release.
3. If the test indicator ? changed from GREEN to RED, this is not a true ground.
4. If the test indicator ? turned off when you pressed the rock switch's front part ("-"), this circuit is likely a direct ground.
5. Keep in mind that high current components such as starter motors ⚙️ will also cause the test indicator ? to turn off in this check.

4.10 Following and Locating Short Circuits

In most cases a short circuit causes a fuse ?️ blowing or a circuit breaker tripping. Here is the best place to begin the search.

1. Remove the blown fuse ?️ from the fuse box.
2. Connect the probe tip ? to each of both contacts in the fuse box and press the rock switch's front part ("-").
3. The side which causes the test indicator ? to turn off when you press the rock switch's front part ("-") is the shorted circuit.
4. Note this wire's identification code or colour. Follow the wire as far as you can along the wiring harness, for instance if you are following a short in the brake light circuit you may know that the wire must pass though the wiring harness at the door sill.
5. Locate the colour-coded wire in the harness and expose it. Probe through the insulation of the wire with the probe tip ? and press the rock switch's front part ("-") to energize the wire.
6. If the test indicator ? turns off, this wire is verified to be the shorted wire. Cut the wire and energize each end with the probe tip ?. The wire which causes the test indicator ? to turn off will lead you to the shorted area.
7. Follow the wire in the shorted direction and repeat this procedure until you find the exact position of the short.

The unit is equipped with a built-in circuit breaker for overload protection. After the circuit breaker trips, it will be reset automatically.
