Possible malfunctions of system of ignition and ways of their elimination
|
|
|
Cause of defect
|
Way of elimination
|
|
The engine is not launched. There is no spark
|
|
|
There is no supply voltage on the coil of ignition or the switchboard
|
By means of a control lamp to find the reason and to eliminate malfunction
|
|
The transistor switchboard, the coil of ignition or the sensor distributor are faulty
|
To check how it is specified in subsection <check of system of ignition on the car>. To replace faulty knot
|
|
Breakdown of the runner or cover
|
To replace the runner and a cover having cracks or progara
|
|
Interruptions in work of system of ignition (difficult launch of the engine, <firing> in the muffler and cottons in the carburetor)
|
|
|
Installation of ignition is broken
|
To check and adjust installation of ignition
|
|
Bad contact of a current carrying vein of a wire of high voltage with a tip or burning out of a current carrying vein
|
To check resistance size between tips of wires and candles which has to be no more: at the 1st cylinder - 900 Ohms; at the 2nd cylinder - 700 Ohms; at the 3rd and 4th - 550 Ohms. If the size of resistance is more than specified size, wires need to be replaced
|
|
Pomekhopodavitelny resistors of the runner of a cover of the sensor distributor or tip of a candle are faulty
|
Resistance of the resistor has to be no more than 15 kOhm. To replace the faulty resistor
|
|
Break of a statorny winding of the sensor distributor
|
To check and if necessary to replace a statorny winding
|
|
The increased fuel consumption and deceleration of power of the engine
|
|
|
Jamming of small weights of the centrifugal regulator of an advancing of ignition
|
To check at the stand and if necessary to make repair
|
|
Strong detonation at sharp opening of butterfly valves
|
|
|
Early ignition
|
To reduce an ignition advancing corner
|
|
The engine has no acceleration performance
|
|
|
Late ignition
|
To increase an ignition advancing corner
