TROUBLESHOOTING
2-5-1. Machine and engine suddenly stops 10/11
Starter motor runs for only 2 seconds when starter switch is turned to START.
Check whether exact meter multiple display shows any error code.
1) when display shows any error code
Reference Fig.: 2-5-1
Error code Check point Check/Cause Action
E61 to E68 1. Connector Check F-R lever potentiometer 1, 2 connector and
traveling controller connector terminal 8, 9, 47, 48,
working controller (C2) connector terminal 1, 2 for
corrosion, breakage, bending and looseness.
If any abnormality is found, connector is faulty.
•
•
Replace connector
or terminal.
2. Harness Measure resistances between F-R lever potentiometer 1,
2 and traveling/working controller terminal wires.
F-R lever potentiometer 1 terminal wire R and traveling
controller terminal 8 wire R
F-R lever potentiometer 1 terminal wire W and traveling
controller terminal 47 wire w, working controller (C2)
terminal 1 wire W
F-R lever potentiometer 1, terminal wire B and traveling
controller terminal 9 wire B
F-R lever potentiometer 2 terminal wire R and traveling
controller terminal 8 wire R
F-R lever potentiometer 2 terminal WR and traveling
controller terminal 48 wire wR, working controller (C2)
terminal 2 wire WR
F-R lever potentiometer 2 terminal B wire B and
traveling controller terminal 9 wire B.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.

Replace harness.
3. F-R Lever
Potentiometer 1
(1) when starter switch is ON, measure voltage between
F-R lever potentiometer 1 terminal inlet wire R and
ground terminal outlet wire B.
Standard voltage : 5
± 0.5
V
(2) when starter switch is ON, measure voltage between
F-R lever potentiometer 1 terminal outlet wire W and
ground terminal wire B.
①
When F-R lever is “N”
Standard voltage : 2.5
± 0.015
V
②
When F-R lever is “F”
Standard voltage : 1.2
± 0.02
V
③
When F-R lever is “R”
Standard voltage : 3.8
± 0.02
V
If above item (1) is OK and any of measurements in item
(2) is NG, F-R lever potentiometer 1 adjustment is faulty.
•
Adjust F-R lever
potentiometer 1 or
replace it even if
measurement is out
of standard after
adjustment.
4. F-R Lever
Potentiometer 2
(1) when starter switch is ON, measure voltage between
F-R lever potentiometer 2 terminal inlet wire R and
ground terminal outlet wire B.
Standard voltage : 5
± 0.5
V
(2) when starter switch is ON, measure voltage between
F-R lever potentiometer 2 terminal outlet wire W and
ground terminal wire B.
①
When F-R lever is “N”
Standard voltage : 2.5
± 0.015
V
②
When F-R lever is “F”
Standard voltage : 3.8
± 0.02
V
③
When F-R lever is “R”
Standard voltage : 1.2
± 0.02
V
If above item (1) is OK and any of measurements in item
(2) is NG, F-R lever potentiometer 2 adjustment is faulty.
•
Adjust F-R lever
potentiometer 2 or
replace it even if
measurement is out
of standard after
adjustment.
