Check point Check/Cause Action
4. Throttle switch (1) when starter switch is ON, measure voltage between
throttle switch terminal 1 inlet wire BW, terminal 4 inlet
wire RB and chassis ground.
Standard voltage : 24 V or more
(2) when starter switch is ON and throttle switch is
“MID”, measure voltage between throttle switch terminal
3 outlet wire WB, terminal 6 outlet wire RW and chassis
ground.
Standard voltage : 24 V or more
(3) when starter switch is ON and throttle switch is
“FULL”, measure voltage between throttle switch
terminal 3 outlet wire WB, terminal 5 outlet wire LB and
chassis ground.
Standard voltage : 24 V or more
If above items (1) and (2) are OK and item (3) is NG,
throttle switch is faulty.
•
Replace throttle switch.
5. MID speed control
relay (B-2)
(1) when starter switch is ON and throttle switch is
“MID”, measure voltage between MID speed control
relay (B-2) terminal 1 inlet wire Rw and chassis ground.
Standard voltage : 24 V or more
(2) when starter switch is ON and throttle switch is
“MID”, measure voltage between MID speed control
relay (B-2) terminal 3 inlet wire RL and chassis ground.
Standard voltage : 24 V or more
(3) when starter switch is ON and throttle switch is
“MID”, measure voltage between MID speed control
relay (B-2) terminal 5 outlet wire G and chassis ground.
Standard voltage : 24 V or more
If above items (1) and (2) are OK and item (3) is NG, MID
speed control relay (B-2) is faulty.
•
Replace MID speed
control relay (B-2).
