Relay

Component testing applies to the following relays:
^ Relay - dipped beam
^ Relay - main beam
^ Daytime running lights relay
^ Stoplamp relay







1. Check break contact.
Measure the resistance between pin 3 and pin 4.
Is the resistance less than 1 ohm?
If yes, GO to step 2.
If no, INSTALL a new the relay.







2. Check close contact
Measure the resistance between pin 3 and pin 5.
Is the resistance greater than 10 kohms?
If yes, GO to step 3.
If no, INSTALL a new relay.







3. Check relay contact in activated condition.
Connect positive terminal of power supply with pin 1.
Connect negative terminal of power supply with pin 2.
Measure the resistance between pin 3 and pin 5.
Does the relay switch audibly and is the resistance less than 1 ohm?
If yes, the relay is OK.
If no, INSTALL a new relay.
