Testing Trailer Lights And Connections - GB HC-CARGO 211083 Mode D'emploi

TESTING TRAILER LIGHTS
AND CONNECTIONS
1. Connect the tester to a good battery.
2. Clip the auxiliary ground clip to the trailer
ground.
3. Probe the contacts at the jack and apply
voltage to them. This lets you check the
function and orientation of the trailer lights.
If the circuit breaker tripped, reset it by
depressing the reset button.
TO ACTIVATE COMPONENTS WITH
POSITIVE (+) VOLTAGE
Contact the probe tip to the positive terminal of
the component, the LED indicator should light
GREEN.
While keeping an eye on the green indicator,
quickly depress and release the power switch
forward (+). If the green indicator changed
instantly from GREEN to RED you may proceed
with further activation. If the green indicator
went off at that instant or if the circuit breaker
tripped, the tester has been overloaded. This
could happen for the following reasons:
• The contact is a direct ground.
• The component is short-circuited.
• The component is a high current component
(i.e., starter motor).
If the circuit breaker tripped, reset it by
depressing the reset button.
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 testing.
Trick: When powering-up components, you can in-
crease the life of your tester switch if you first press
the switch, then contact the tip to the component.
The arcing will take place at the tip instead of the
contacts of the switch.
