Mini ISO Relay: Testing and Inspection
Continuity Checking With Meter
Use 73III Automotive Meter to check for the continuity between terminal 85 and all other terminals. If resistance is 5 ohms or less between terminal 85
and any other terminal, replace the 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 73III Automotive Meter set in the volts position to check for voltage at terminal 87A. If battery
voltage is not indicated, replace the relay. If battery voltage is indicated, connect a third jumper wire to terminal 85 and ground the jumper wire to a
known good ground. Check for voltage at terminal 87. If battery voltage is not indicated, replace the relay.
