CHECKING RELAYS

Check each relay for continuity with the pocket tester. If the continuity reading is incorrect, replace the relay.
Pocket tester
    90890-03112

Analog pocket tester
    YU-03112-C
1. Disconnect the relay from the wire harness.
2. Connect the pocket tester (Ohms. x 1) and battery (+12VDC) to the relay terminal as shown.

    Check the relay operation.

    If out of specification -> Replace.
Relay Unit (Starting Circuit Cut-Off Relay)
1. Positive battery terminal
2. Negative battery terminal
3. Positive tester probe
4. Negative tester probe
Result
    Continuity (between "3" and "4")
CHECKING THE RELAY UNIT (DIODE)

Relay unit (diode)

1. Check:
    • Relay unit (diode)

       If out of specification -> Replace.

Analog pocket tester
    YU-03112-C
The pocket tester or the analog pocket tester readings are shown in the following table.
Continuity
    Positive tester probe -> sky blue "1"
    Negative tester probe -> black/yellow "2"

No continuity
    Positive tester probe -> black/yellow "2"
    Negative tester probe -> sky blue"1"

Continuity
    Positive tester probe -> sky blue
    Negative tester probe -> blue/yellow "3"

 No continuity
    Positive tester probe -> blue/yellow "3"
    Negative tester probe -> sky blue"1"

Continuity
    Positive tester probe -> sky blue
    Negative tester probe ->sky blue/white "4"

No continuity
    Positive tester probe -> sky blue/white "4"
    Negative tester probe -> sky blue"1"

Continuity
    Positive tester probe -> blue/green "5"
    Negative tester probe -> blue/yellow "3"

No continuity
    Positive tester probe -> blue/yellow "3"
    Negative tester probe -> blue/green "5"
       a. Disconnect the relay unit from the wire harness.
       b. Connect the pocket tester (ohm x 1) to the relay unit terminals as shown.
       c. Check the relay unit (diode) for continuity.
       d. Check the relay unit (diode) for no continuity.
Starter Relay
1. Positive battery terminal
2. Negative battery terminal
3. Positive tester probe
4. Negative tester probe
Result
    Continuity (between "3" and "4")
