Both the high voltage wires of *1 and *2 should be checked to make sure that the wire of spark piston is connecting. If sparks come out when EST plug(wire 4) is being pull off, that means the output voltage of signal picking coil is too low to make EST work. If *3 has sparks, that means the problem is in electricity distributor and spark distributor. When the *4 is in normal condition, there should be battery voltage on both terminals c and + of igniting module, and the voltage is tend to be low, that mean there are breaks or resistance value is too high between distributor and igniting coil or switch.

Washer pump is controlled by a independent switch. The wiper has 4 gears of fog, off, low and high in total. When it is at the fog gear, the current comes from wiper fuse(25A), in the meantime, the relay in the P switch acquires the current and makes the terminals pull in, then the current goes into the motor, and the motor run for a course at a low speed, in which the course in interrupted. If therelay didn't pull in, the motor wouldn't work normally. In the Figure, there is no the electric delaying display circuit.

When the igniting switch is at the ON gear, computer ECM will start the fuel pump relay and run the pump in the oil box. When the engine starts or runs, if ECM receives the igniting reference pulse signal, the fuel pump will go on to work; if there is no reference pulse signal, then the ECM will shut down the pump in 2 secondsafter the igniting switch is on.
It will lead to a long starting time of the engine if the oil pump relay doesn't work, especially when the temperature of the engine is low or the engine oil viscosity is high.

The circuit can be used to adjust the speed of the ShenLI electromotor or the single-phase asynchronous motor, it is the half-wave controlled rectifier circuit. When there is no load, the armature has high EMF, so that at the end of the half cycle, the thyristor is triggered immediately. When there is load, the armature's voltage reduces, the thyristor will be triggered in the rising voltage part. The L1, L2 and the capacitances C4 and C5 can be used to resist the interference.

1.Introduction It should be in accordance with circuits when doing tests on oil injection control system, and on the basis of exact observation and practice, only after further analysis and integration can we find reliable methods. If the fast repairing motor indicator is on all the time, before we get down to solving the problem, we should ask the driver about the cause. If the engine rotates but not runs, we can solve the problem by the fault judging course in the following descripiton.

Many machines can only be running in a certain temperature range for the best and the most economical status. If the temperature exceeds a certain permissible operating temperature, the machine may be damaged or reduce its service life. So we can use the protection circuit. This circuit uses the thermistor RH as the sensor. In order to ensure that there is no direct electrical contact between the protection circuit and the equipment, we can use the relay control.
In the condition of trouble-free or given temperature, the machine is connected by the relay. Otherwise, the relay will release and the motor will cut off.
