Surge voltage waveform with any charging cable
disconnection.
• May be VHmin = 6.5 V in high electric load shedding
or unloaded condition with the battery fully charged.

Load Connected To the P Terminal
P terminal output current: 0.5 A max (average
current).
• Ensure that there is no load short circuit or
wrong wiring.
• Do not connect inductive or capacitive load
(connection of such load subject to discussion
of the specification).
• When detecting a waveform, take the noise and
VHmin into consideration.
• Take the surge voltage into consideration for the
input of the load.
• Use the actual equipment for sufficient check of
the operation of the load.

[3] ENGINE CONTROL UNIT (ECU)
The ECU will use signal inputs, from the engine
sensors, to control the fuel metering and speed control,
while the engine is running. As well, the ECU will provide
diagnostic control, over the fuel system.

[4] ENGINE COOLANT TEMPERATURE SENSOR
Ignition timing, fuel rate, and boost levels can be
configured to vary with engine coolant temperature. This
is typically done at very cold or very hot conditions.
Coolant temperature is also used in the airflow models in
the ECU.
