2-7-8. Vibration indicator lamp does not light
Check that vibrator can be operated.
Reference Fig. : 2-7-2
Check point Check/Cause Action
1. Harness (1) Measure resistance between vibration select switch
terminal 5 wire YB and diode unit terminal E wire YB.
Standard resistance : 10 Ω or less
(2) Measure resistance between vibration select switch
terminal 2 wire YR and diode unit terminal A wire YR.
Standard resistance : 10 Ω or less
(3) Measure resistance between diode unit terminal F wire
Br and combination meter connector terminal wire No.
31 wire Br.
Standard resistance : 10 Ω or less
If above item (1), (2) or (3) is NG, harness is faulty. •
Repair or replace
harness.
2. Diode Unit (1) when starter switch is ON and vibration select switch is
“ ”, measure voltage between diode unit terminal A
inlet wire YR and chassis ground.
Standard voltage : 24 V or more
(2) when starter switch is ON and vibration select switch is
“
”, measure voltage between diode unit terminal E
inlet wire YB and chassis ground.
Standard voltage : 24 V or more
(3) when starter switch is ON, measure voltage between
diode unit terminal F outlet wire Br and chassis ground.
Standard voltage : 24 V or more
If above items (1) and (2) are OK and item (3) is NG,
diode unit is faulty.
•
Replace diode unit.
3. Combination Meter
(Vibration indicator
lamp)
(1) when starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Battery terminal wire No. 70 inlet wire WR and ground
terminal wire B
Starter switch terminal wire No. 35 inlet wire YW and
ground terminal wire B
Standard voltage : 24 V or more
(2) when starter switch is ON, vibration mode change
switch is “CONT” and vibration select switch is “ ”
or “
”, measure voltage between combination meter
vibration terminal wire No. 31 inlet wire Br and chassis
ground.
Standard voltage : 24 V or more
If above items (1) and (2) are OK and vibration indicator
lamp does not light, combination meter is faulty.
