TUTORIAL FOR TESTING A 5-PIN RELAY

Ce tutorial aims to explain to you how to test a 5 pin relay. THE relay is an electrically operated switch that allows an electrical circuit to control one or more circuits by opening and closing its contacts in response to the coil being turned on or off.

Testing a relay is a relatively simple task that you can do yourself. By following the steps above, you can determine if your motorcycle's relay is working properly or if it needs to be replaced.

An SP relayDT is made up of 5 pins in total (3 for contacts, 2 for the coil).

Generally reliable, the relay can fail like any mechanical component causing problems with starting, indicators or headlights.

HOW TO TEST A 5-PIN RELAY

Test 5 pin relay step 1

1) The relay is an electrical organ making it possible to distribute power from an order issued par the control part. The relay allows the opening and closing of an electrical circuit.

Test 5 pin relay step 2

2) Start par Test the relay resistance to check the continuity of the control circuit. Set the multimeter to 2K ohm.

The value obtained must be between 0 and a few ohms. If the resistance is too high or infinite, this indicates that the relay is faulty and needs to be replaced.

Test 5 pin relay step 3

3) Place the probes on pin 85 and pin 86.

Test 5 pin relay step 4

4) If the value displayed on the multimeter is less than or equal to 350 ohms, then the winding is functional.

Test 5 pin relay step 5

5) Check the continuity of the closed contact.

Test 5 pin relay step 6

6) Place the probes on pin 3 and pin 87A.

Test 5 pin relay step 7

7) If the value displayed is less than or equal to 1 ohms, the contact is functional.

Test 5 pin relay step 8

8) Check the continuity of the open contact (so no continuity).

Test 5 pin relay step 9

9) The multimeter probes are placed on pin 87 and pin 30. No continuity, which is normal since the contact is open. The open contact works correctly.

Test 5 pin relay step 10

11) Now test the relay with a 12V supply to verify that the relay is correctly receiving the supply voltage.

Connect the battery to the relay by connecting pin 86 and pin 85. Polarity has no effect.

Test 5 pin relay step 11

11) The relay clicks. The switch was activated. The winding works correctly.

Test 5 pin relay step 12

11) The relay clicks. The switch was activated. The winding works correctly.

Test 5 pin relay step 13

11) Check the continuity of contact 2 closed (therefore continuity) by placing the probes on pin 30 and pin 87.

Test 5 pin relay step 14

11) If the value displayed on the multimeter is less than or equal to 1 ohm, then the closed contact is functional.

Test 5 pin relay step 15

11) Check the continuity of contact 1 open (therefore no continuity) - probes placed on 30 and 87A.

Once the various measurements have been carried out, analyze the results obtained to determine if your relay is in good working order or if it needs to be replaced. If all the measured values ​​comply with the manufacturer's specifications, this means that the relay is working correctly and that your problem may come from another component (starter, battery, wiring, etc. ). On the other hand, if one of the measurements indicates a failure of the relay, it is time to replace it.

Remember to follow the safety instructions when handling the electrical elements of your vehicle, and do not hesitate to call a professional in case doubt about your mechanical skills.
