INSTRUCTION MANUAL FOR:
RELAY CIRCUIT DIAGNOSTIC
TESTER
MODEL No: TA130
Your new tester is produced and manufactured to a high standard of dependability and will, if used according to these instructions and
properly maintained, give you years of trouble free performance.
Important: READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS AND CAUTIONS. USE
THIS TESTER CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE
AND/OR PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. RETAIN THESE INSTRUCTIONS FOR FUTURE USE.
1. SAFETY PRECAUTIONS
2. INTRODUCTION
IF YOU ARE IN ANY DOUBT ABOUT ELECTRICAL
SAFETY CONSULT A QUALIFIED ELECTRICIAN.
Only for use with 12V - 24V DC systems.
DO NOT use with industrial 110V systems.
DO NOT use for domestic 110V - 230V applications.
DO NOT use on any circuit directly or indirectly
connected to AC lines or any other AC power source.
Always check the instructions and procedures indicated in
the vehicle service manual before attempting to
disconnect any part or sub-system of the electrical circuit.
DO NOT use if leads are damaged or if any wires are
bared in any way.
DO NOT use the equipment when you are tired or under
the influence of alcohol, drugs or intoxicating medicines.
DO NOT use this tool for any purpose other than that for
which it has been designed.
Observe standard workshop safety procedures when
using the tester.
Ensure vehicle ignition is switched OFF before connecting
or disconnecting the tester.
Keep the work area clean, uncluttered and ensure there
is adequate lighting.Keep tools and other items away
from the engine, and ensure you can see the battery and
working parts of engine clearly.
Maintain correct balance and footing. Ensure the floor is
not slippery and wear non-slip shoes.
Remove ill fitting clothing. Remove ties, watches, rings
and other loose jewellery. Contain or tie back long hair.
Keep children and unauthorised persons away from the
working area.
DO NOT disassemble. The tester must be checked by
qualified service personnel only.
DO NOT get the tester wet or use in damp or wet
locations or areas where there is condensation.
DO NOT use the tester for any purpose other than that for
which it is designed.
DO NOT pull by the cables to free from the relay socket.
When not in use, store carefully in a safe, dry, childproof
location. Avoid extremes of temperature.
2.1 Introduction
Fast, accurate and safe relay circuit tester that tests the
supply, earth and trigger wires within the circuit. Simply
remove the relay and install the corresponding dummy relay.
Includes a universal y lead for non-standard relay pin
congurations. Earth, supply and trigger terminals will be
displayed as a green or red LED. The tester can also be used
to power components by simulating the relay in the on/off
positions using the test button.
3. OPERATING INSTRUCTIONS
Note:Please refer to g.1 overleaf for identication of the
tester's components.
pWARNING! Before use ensure that you have read,
understood and apply Section 1 safety precautions.
p WARNING! All pin numbers on the dummy relays
must correspond with the appropriate pin numbers
on the vehicle or damage may result when using
the test buttons. This is especially important when
using the universal y lead.
3.1. Connection
3.1.1. Connect the red clip on the tester to the positive terminal
(+) on the vehicle battery.
3.1.2. Connect the black clip on the tester to the negative
terminal (-) on the vehicle battery.
3.1.3. All the LEDs on the tester will illuminate, indicating that
there is no voltage or earth present at the test plug.
3.1.4. Remove the relay from the circuit to be tested and install
the correct type of dummy relay into the relay socket
(There are six different types of dummy relay supplied
with the kit plus a universal fly lead for use with any type
of vehicle relay socket).
3.1.5. Attach the test plug to the dummy relay.
3.2. Testing
3.2.1. Any circuits that have a voltage will be indicated by the
red LED illuminating.
3.2.2. Any circuits going to earth will be indicated by the green
LED illuminating.
Note: With any relay circuits, there should be a minimum of at
least one red and one green LED illuminated when testing
a circuit. Both LEDs should not be illuminated at the
same time for an individual circuit as this will indicate a
fault within that circuit. Typically circuits 86 and 30 will
illuminate red whilst circuit 85 will illuminate green.
3.2.3. If the relay circuits are serviceable (as indicated by the
LEDs), they can be energised by pressing the test
button 87 (and 87A for a ve pin relay). For example: if
the horn relay circuit is under test, depressing the test
button will sound the horn.
3.3. Additional Testing
3.3.1. Additional diagnostic tests may be conducted using a
Digital Automotive Analyser or test light in conjunction
with the test terminals.
Note: There is no resistance in the tester between the test
terminals and the vehicle circuit.
3.4. Universal Fly Lead
3.4.1. The coloured wires on the universal y lead have
numbered tags to identify which pin the coloured wires
correspond to.
3.4.2. Should the numbered tags become lost or illegible, the
guide overleaf indicates which coloured wire
corresponds to which particular pin.
