Automotive Electric System Tester
◆
Thank you for purchasing Automotive Electric System
Tester. It’s your best tool for testing automotive electrical
problems
After simply hooking up two clips to the vehicle’s battery,
user is able to operate it with below key functions.
«Quickly check if a circuit is Positive, Negative or Open by
probing it and observing the RED or GREEN LED.
«Quickly activate and check electric components by
pressing power switch to (-) or (=) position to determine their
electronic and grounding status.
«Test continuity of switches, relays, diodes, fuses and
wires by connecting them between the auxiliary ground lead
and the probe tip and observing the GREEN LED.
«Find faulty ground connections instantly.
«Follow and locate short circuit.
This is overload protected by disconnecting circuit and
beeping alarm to ensure safety of user and battery. Before
using this tester, please read the instruction manual carefully.
Introduction
◆ Warning

1.Quick Self-Test
Please complete self-test to determine tool’s functional
availability prior to using it.
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
◆Operation Instruction
★ Connect black clip to negative terminal of vehicle's
battery.
★ Press button to “-” side , the LED should light RED.
★ Press button to “=” side , the LED should light GREEN.
★ Loose the button and contact the probe tip to positive
terminal of battery , the LED should light RED.
★ Loose the button and contact the probe tip to negative
terminal of battery , the LED should light GREEN.
★ Press button to “-” side , the LED should light RED. Then
have the probe tip quickly contact negative terminal of battery
(there will be a little sparks), LED indicator turns to GREEN
with buzzer sounding.
NOTE: DO NOT operate it in area with combustible gas,
dust and explosive conditions. NOT allowed to use it with AC
and over 24V DC circuit.
2.Polarity Testing
This tool can test uncertain polarity of contact in the circuit
of vehicle.
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
★ Connect black clip to negative terminal of vehicle's
battery.
★ Contact the probe tip to a positive (+), the LED should
light RED.
★ Contact the probe tip to a negative (-), the LED should
light GREEN.
NOTE: DO NOT operate it in area with combustible gas,
dust and explosive conditions. NOT allowed to use it with AC
and over 24V DC circuit.
3.Continuity Testing
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
★ Connect black clip to negative terminal of vehicle's
battery.
★ Connect auxiliary ground lead to one side of tested wire
along with probe tip connecting to the other side. When
continuity is present, the LED will light GREEN. If LED does
NOT light up, NO continuity present.

NOTE: DO NOT operate it in area with combustible gas,
dust and explosive conditions. NOT allowed to use it with AC
and over 24V DC circuit.
4.Testing Components Out of Vehicle’s
Electrical System
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
★ Connect black clip to negative terminal of vehicle's
battery.
★ Connect auxiliary ground lead to negative terminal of
tested component.
★ Press button to (-) side with LED lighting RED. Contact
the probe tip to positive terminal of tested component to active
the component. If LED turns to GREEN with buzzer sounding,
stop testing and check the component if defective or not, or
rating current of component is higher than that of this tester.
NOTE: DO NOT operate it in area with combustible gas,
dust and explosive conditions. NOT allowed to use it with AC
and over 24V DC circuit.
5.Testing Components in Vehicle’s
Electrical System
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
★ Connect black clip to negative terminal of vehicle's
battery.
★ When component’s control switch is located at the side
of positive terminal of component , press button to “-” side to
have LED light RED. Contact probe tip to the positive terminal
of component. The component will be activated.

★ When component’s control switch is located the at side of
negative terminal of component , press button to “=” side to have
LED light GREEN. Contact probe tip to the negative terminal of
component. The component will be activated.
★ When it comes to check each little metal points in
lamp’s socket , connect auxiliary ground lead to ground of
component. Then press button to “-” side to have LED light RED.
Contact probe tip to each metal points individually. The
component will be activated.
★ If color of LED changes along with buzzer sounding, stop
testing and check the component if defective or not, or rating
current of component is higher than that of this tester.
NOTE: DO NOT operate it in area with combustible gas,
dust and explosive conditions. NOT allowed to use it with AC
and over 24V DC circuit.
6.Jumper Lead Operation
The black clip and auxiliary ground lead are connected
directly through the unit. User can consider it as a long jumper
test lead by leave the red clip disconnected from the battery.

and over 24V DC circuit.
7.Grounding Testing
For some components of which negative terminal is
required to be well grounded for large current flowing, this
tester is a good tool to test their grounding.
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
★ Connect black clip to negative terminal of vehicle's
battery.
★ Press button to “-” side , the LED should light RED , and
positive voltage is supplied. Then have the probe tip quickly
contact negative terminal of component as close as possible,
LED indicator turns to GREEN with buzzer sounding, which
means it is well grounded. If NOT, the LED remains RED
without any buzzer.

8.Short Circuit Following and Locating
In most cases short circuit or instant overload of component
will lead to blown fuse or circuit breaker tripping. This tester can
search and locate the problem.
★ Unroll the leads.
★ Connect red clip to positive terminal of vehicle's battery.
★ Connect black clip to negative terminal of vehicle's
battery.
★ Press button to “-” side , the LED should light RED , and
positive voltage is supplied.
★ Remove the blown fuse from the fuse box and begin
tracking from two terminals of the fuse socket. Use probe tip
quickly contact wire. If LED lights GREEN with buzzer, short
circuit or overloading component appears in this side. Please
note this wire’s color or identification code. Follow the wire as far
as you can along the wiring harness. Locate the color-coded wire
in the harness and expose it. Cut the wire. Follow the wire in the
shorted direction and repeat this process until the short is
located. If there are components in the following wire, check the
components individually if good or not.
NOTE: DO NOT operate it in area with combustible gas,
dust and explosive conditions. NOT allowed to use it with AC
and over 24V DC circuit.
