Check following item before troubleshooting.
• No blown fuses and power is applied up to fuses.
• When measuring voltage and current without disconnecting connectors, refer to “measuring voltage and current
following using tester” (P.10-006 to P.10-008).
• Check any ground circuit which belongs to components to be checked.

Replace each bulb.
2. Lighting Switch (1) When starter switch is ON, measure voltage between
lighting switch terminal 1 inlet wire WG, terminal 4 inlet
wire WG and chassis ground.
Standard voltage: 12 V or more
(2) When starter switch is ON and lighting switch is “ ”,
measure voltage between lighting switch terminal 3
outlet wire RL and chassis ground.
Standard voltage: 12 V or more
(3) When starter switch is ON and lighting switch is “ ”,
measure voltage between lighting switch terminal 5
outlet wire Lg and chassis ground.
Standard voltage: 12 V or more
• If above item (1) is OK and item (2) or (3) is NG, lighting
switch is faulty.
Replace lighting switch.
3. Lighting Relay (1) When starter switch is ON, measure voltage between
lighting relay terminal 3 inlet wire WG and chassis
ground.
Standard voltage: 12 V or more
(2) When starter switch is ON and lighting switch is “ ”,
measure voltage between lighting relay terminal 1 inlet
wire Lg and chassis ground.
Standard voltage: 12 V or more
(3) When starter switch is ON and lighting switch is “ ”,
measure voltage between lighting relay terminal 5 outlet
wire BrW and chassis ground.
Standard voltage: 12 V or more
• If above items (1) and (2) are OK and item (3) is NG,
lighting relay is faulty.
Replace lighting relay.
