Engine General Information and Diagnosis: 1A-9
Action:
NOTE
If the engine is automatically stopped due to the caution system, the engine can be started again.
The caution system will repeatedly activate until the cause is eliminated.
Reset:
Close the throttle completely and then shift into neutral.
System reset will occur when the cylinder temperature drops below the limits shown below. However, the system may
be activated again unless the cause for overheat (such as insufficient water) is removed.
Low Battery Voltage Caution System
Condition 1:
The system is activated when the battery voltage decreases to less than 9 volts for 30 seconds.
Condition 2:
The system is activated if the battery voltage is less than 2 Volts for more than 2 seconds when the ignition switch is
turned “ON” and the engine is not running.
Action:
Reset:
Condition 1:
The caution system is automatically reset when battery voltage increases to more than 9 volts.
Refrain from using electrical equipment requiring high amperage, such as hydraulic trim tabs, hydraulic jack plate, etc.,
after this caution is activated.
Condition 2:
For the caution system to engage under this condition, possibilities such as a deteriorated battery, poor battery cable
connection, battery switch in the “OFF” position, etc., must be inspected.
To cancel the caution system activation for these conditions, check all power source related items and eliminate the
problem.
Engine speed • Automatically reduced to approx. 3 000 r/min. maximum by intermittent fuel
injection and ignition signals.
• The engine automatically stops 3 minutes after the caution system is
activated.
Caution lamp • “TEMP” lamp lights continuously.
• “REV-LIMIT” lamp lights continuously during engine speed rev-limiter
activation (3 000 r/min. or higher).
Caution buzzer • Sounds in a series of long (1.5 sec.) beeps.
