AUXILIARY STARTER RELAY
Apply 12V voltage between the positive and
negative terminals of the starter relay. Test the
connection between A and B with the multimeter.
If the starter relay clicks and is connected,
the starter relay is OK.
When there is no voltage of 12V, they are not
connected, the starter relay is OK.
The multimeter is set to 1x10Ω.
Auxiliary starter relay coil resistance:
3.5-4Ω
EFL SYSTEM
schematic diagram of EFI system
The function of EFI system includes two parts: fuel injection management and ignition management, which
are realized by the following institutions.
(1). ECU:
it is responsible for the receiving of sensor signal, the formulation of control strategy, and the issue of
control signal.
(2). Oil supply device:
it is composed of oil pump, tubing and injector. The pump pressurizes the fuel to 250
KPA. The injector is installed on the engine inlet to control the injection timing and fuel injection amount.
(3). Ignition device:
it is composed of ignition module, high voltage wire and spark plug. The ignition module
