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.
CHECKING THE TURN SIGNAL RELAY

1. Check:
    • Turn signal relay input voltage

       If out of specification ->The wiring circuit from the main switch to the turn signal relay coupler is
       faulty and must be repaired.
Turn signal relay input voltage
    DC12V
       a. Connect the pocket tester (DC 20 V) to the turn signal relay terminal as shown.

Analog pocket tester
    YU-03112-C
       • Positive tester probe -> brown/green " 1 "
       • Negative tester probe -> ground
       b. Turn the main switch to "ON".
       c. Measure the turn signal relay input voltage.

2. Check:
    • Turn signal relay output voltage

       If out of specification -> Replace.
Turn signal relay output voltage
    DC12V
       a. Connect the pocket tester (DC20V) to the turn signal relay terminal as shown.
Pocket tester
    90890-03112

Analog pocket tester
    YU-03112-C
       • Positive tester probe -> brown/white " 1 " or yellow/red "2"
       • Negative tester probe -> ground
       b. Turn the main switch to "ON".
       c. Measure the turn signal relay output voltage.
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.
