^
Using the multimeter, check for continuity between terminal 1 and all other terminals.
-
If the resistance is 5 ohms or less between terminals 1 and any other terminal, install a new relay.
-
If the resistance is greater than 5 ohms, continue with the test.
^
Using two jumper wires, connect relay terminals 2 and 3 directly to the positive battery terminal.
^
Using the multimeter set in the volts position, check for voltage at terminal 4.
-
If battery voltage is not indicated, install a new relay.
