Measure the resistance between relay terminal COM and all other terminals. If any resistance is 5 ohms or less, replace the HEAD relay. Otherwise, continue with the test.
Use a jumper wire to apply ground to terminal COIL. Use another jumper wire to apply voltage to terminals COIL and NO. Measure the voltage at terminal COM. If voltage is less than 10 volts , replace the HEAD relay. Otherwise, return to the pinpoint tests. See: Lighting and Horns\Headlamp\Testing and Inspection\Pinpoint Tests
