Relay Tester Kit
• This is the device to test 3 popular vehicle relays.
• The testing result will be displayed by LED indication.
• Technician is able to use the device to figure out the condition of the relay,
and so speculating the problem in the vehicle.
• Use the relay adapter to plug into the relay tester, suitable to connection
multiple styles relay.
• Features:---
With CE & UKCA Approvals. Power Supplied: 12V / 24V vehicle battery.
Support both 4 pin / 5 pin relay. Problem pin indication.
Colored wires of pin number for easy identification.
• Working Temperature: 0 ~ 50°C ( 32 ~ 122°F ); < 85%RH.
• Storage Temperature: -20 ~ 60°C ( -4 ~ 140°F ); < 85%RH
• Operation:---
A.) Relay Tester
Base on the specification of the relay, user needs to select the correct relay pin type
by switch the “4 pin / 5 pin switch” to its corresponding position, and connect the
battery clips to 12V or 24V vehicle battery. Install the relay into the relay socket,
and press and hold the “Testing” button to start the test.
The test result indication will keep flashing during the tester; do not release the
testing button until the result has shown by the “Test result indication”.
• Possible result is as below:---
(1) If “OK” lights up, it means the relay is function correctly.
(2) If “87”indication stays light, it means pin No. 87 is short circuit with other pins.
If “87” indication is flashing, it means the connection of pin No. 87 is poor.
This may be open loop or poor conductivity due to oxidization.
For both conditions, user has to replace the relay and check the relative
connectors; make sure the voltage passing through the pin is normal.
(3) If “87a” indicationstays light, it means pin No. 87a is short circuit with other pins.
If “87a” indication is flashing, it means the connection of pin No. 87a is poor.
This may be open loop or poor conductivity due to oxidization.
For both conditions, user has to replace the relay and check the relative
connectors; make sure the voltage passing through the pin is normal.
(4) If “coil” indication stays light, it means the coil within the relay is damaged.
Please replace the relay, and check the specification of the relay; make sure
the voltage meets the requirement of the vehicle.
• CAUTION: To prevent damaging the relay and to obtain an accurate test result,
please make sure the specified voltage of the relay has satisfied the
vehicle battery connected with the tester. Make sure the “4 pin / 5 pin
switch”position meets the pin number of tested relay. Do not press
and hold the “TEST”button after the test result has appeared.
• B.) Relay Adapter
1. Plug the relay adapter into the relay tester.
2. Connecting the alligator clips of the adapter with the relay according to the
pin number, and press the “TEST” button to start the test.
• CAUTION: Make sure the pin number on the relay adapter and the connected
relay are the same, otherwise the testing result will be incorrect.
In order to prevent short circuit between alligator clips, make sure the
insulation jacket of the alligator clips has been pushed to the position
where no conductor is under exposure.
