Starter Relay: Testing and Inspection
MINI ISO RELAY
Use the 73III Automotive Meter to check for continuity between terminal 85 and all other terminals. If resistance is 5 ohms or less between
terminal 85 and any other terminal, install a new relay. If resistance is greater than 5 ohms, continue with the test. Use two jumper wires to connect
relay terminals 86 and 30 directly to the positive battery terminal. Use the 73 Digital Multimeter set in the volts position to check for voltage at
terminal 87A. If battery voltage is not indicated, install a new relay. If battery voltage is indicated, connect a third jumper wire to terminal 85 and
ground the jumper wire to a know good ground. Check for voltage at terminal 87. If battery voltage is not indicated, install a new relay.
