The electrical multifunctional testing device HAZET 2152-5 is a tester which reduces the time needed for checking automotive electrical systems from 12 to 24 volts. After connecting the testing device to the battery, the motorcar mechanic can determine by one glance at the red/green LED if the electrical circuit is positive, negative or open without having to release the feeder clamps from the battery. The rocker switch allows the car mechanic to conduct a positive or negative current to the tip in order to test the functioning of electrical components. The device is protected against short circuits. It allows to detect and locate bad ground contacts instantly without performing voltage drop tests. It allows to follow-up and locate short circuits without having to waste precious fuses. The multifunctional testing device can also be used for continuity tests (for this purpose use the negative auxiliary clamp, too). By touching the rocker switch you will find out at once if the testing device is functioning. The 6 m cable allows to test the complete electrical system of the car without having to search constantly for the ground contacts.

Please read the operation instructions carefully before using the testing device.

While operating the rocker switch battery current is directly conducted to the tip which may cause sparks when contacting ground or certain circuits. Therefore, the electrical multifunctional testing device must not be used close to flammables such as gasoline or its vapors. The spark of a current-carrying testing device can ignite such vapors. Please observe the same safety advices as in case of using e.g. an arc welder.

The HAZET electrical multifuncional testing device 2152-5 must not be

used with 110/230 volt house current. It is only intended for use with 12 to 24 volt systems. Any claims against the manufacturer because of improper use are void.

Important notice:

You can increase the life of your multifunctional testing device if, while testing components, you operate the rocker switch before connecting the tip to the component. The arcing will take place at the tip rather than at the switch contacts.

Multifunctional testing device 2152-5 with optical and audible signal functions

HAZET 2152-5 is equipped with an optical and an audible signal function. After connecting it to a battery, the optical and audible signals are activated.

• The testing area is lit which is very helpful for working in dark areas.
• The polarity signal is enforced by the audible signal. If the tip contacts a positive circuit, there is a permanent signal. If the tip con tacts a negative circuit, there is a pulse signal.

POSITIVE = permanent signal NEGATIVE = pulse signal

Do not use on electronic control units!

③ Design and Function

Connecting

First connect the testing device to the battery.

• Unroll the cable.
• Connect the red clamp to the positive pole of the battery
• Connect the black clamp to the negative pole of the battery

If you want to use the extension cable, disconnect the adapter of the battery clamp and put the extension cable in between.

Self testing

• Push the rocker switch forward (+). The light (LED) should be red.
• Push the rocker switch backward (-). The light (LED) should be green.
  • The testing device is ready for use.
  If the LED is off, push the reset switch (on the side) and start self testing again.

③ Design and Function

• If the tip of the testing device contacts a positive circuit, the LED is red.
• If the tip of the testing device contacts a negative circuit, the LED is green.
• If the tip of the testing device contacts an open circuit, the LED is off.

red = positive green = negative

Do not use on electronic control units!

Continuity test

For checking the continuity of a component (wire, cable, switch, etc.), it has to be disconnected from the electrical circuit of the car.

• Connect the negative clamp to the component and check the continuity with the tip.
• The continuity is confirmed by a green LED.

No continuity Green = Continuity No light = No continuity Continuity 12 V

Activating components outside the electrical system of the car

If the multifunctional testing device is used with an auxiliary ground lead, components can be activated and their function can be tested.

• Connect the negative clamp to the negative terminal of the component being tested.
• Connect the proof tip to the positive terminal of the component. The LED is GREEN indicating continuity for the component.

• Watch the LED and push the rocker switch forward (+) and immediately release it again. If the LED changes without delay from GREEN to RED, you may continue. If the green LED extinguishes or if the circuit breaker is released, the testing device is overloaded. This could be due to the following reasons:

• The contact is a direct ground contact or its circuit is negative.

• The component has a short circuit.
• The component is a high amperage component (e.g. starter motor).

If the circuit breaker has been released, push the reset button.

• The black clamp is directly connected to the jumper lead
  • The red clamp has no particular function here

Caution! Avoid short circuits in this function. The leads are not protected by the circuit breaker! The device can be damaged.

Positive current is now flowing directly through this lead red clamp hanging loose Engine and is activating the relay

Do not use on electronic control units!

Detecting bad ground contacts

Mostly, the reason for a bad ground contact is a loose cable connection, a loose cable in the lug or an oxidized contact. Such defects can only be detected by a voltage drop. However, the necessary tests are very time-consuming.

With the multifunctional testing device you can detect bad ground contacts without such tests.

Connect the multifunctional testing device to the car battery (see on page 21).

Connect the proof tip to the presumably bad contact. The LED is green (continuity to ground).

• Push the rocker switch forward (+) and watch the LED.
• If the LED changes from GREEN to RED, the ground contact is bad.
• If the circuit breaker is released, the ground contact is fine.

Following-up and locating short circuits

• Start searching for the short circuit in the fuse box.
• Remove the fuse from the fuse box.
• Use the testing device to direct positive current to each of both contacts in the fuse box. At the side of the short circuit the circuit breaker of the testing device is released.
• Follow the cable through the cable harness as far as possible.
• Pull the cable out of the cable harness and engrave with the proof tip. The LED is green.
• Push the rocker switch forward (+) to find out if you pulled out the appropriate cable (circuit breaker must release).
• Cut the cable and direct current to each extremity of the cable. The circuit breaker is released again on the side of the short circuit.
• Repeat this process until the short circuit is located.

③ Design and Function

How to avoid blowing fuses

Due to the increased power rating of the testing device, there is more current flowing when the switch is operated. You will find out that the testing device is supplying higher nominal current to the electrical devices.

Caution: Grounding a positive circuit with the testing device can blow a fuse, if the fuse is connected directly in series to the circuit being grounded. Please see figure.

In this circuit the 30 A fuse can blow if the rocker switch is pushed backwards (-). Make sure that the fuse is connected to the device.

This circuit can be ground without destroying the fuse.
