5.4. Possible malfunctions of ignition, their reason and elimination methods

THE REASON
ELIMINATION METHOD
The engine is not started
The current does not pass through breaker contacts:
  – Breaker contacts are polluted, oxidised or have burnt; the increased backlash between contacts
  – Smooth out contacts and adjust a backlash between them
  – Fastening is weakened or tips of wires in low voltage chains, breakage in wires or their short circuit with weight are oxidised
  – Check up wires and their connections; the damaged wires replace
  – The ignition switch (contacts «30/1» and «15» do not become isolated) is faulty
  – Check up, replace a faulty contact part of the switch of ignition
  – The condenser is punched
  – Replace the condenser
  – Breakage in a primary winding of the coil of ignition
  – Replace the ignition coil
Breaker contacts are not disconnected:
  – Backlash adjustment between breaker contacts is broken
  – Adjust a backlash between contacts
  – It is worn strongly out textolite колодка or the plug рычажка the breaker
  – Replace contact group
  – The bearing of a mobile plate of the breaker has failed
  – Replace the bearing or the ignition distributor
The high voltage to spark plugs does not move:
  – Are leaky planted in nests, have come off or tips of wires of a high voltage are oxidised; wires their isolation is strongly polluted or damaged
  – Check up and restore connections, clear or replace wires
  – Deterioration or damage of a contact piece of coal, its lag in a cover of the distributor of ignition
  – Check up and, if necessary, replace a contact piece of coal
  – Current leak through cracks or прогары in a cover or a rotor of the distributor of ignition, through a deposit or a moisture on an internal surface of a cover
  – Check up, clear a cover of a moisture and a deposit, replace a cover and a rotor if in them there are cracks
  – перегорание the resistor in a rotor of the distributor of ignition
  – Replace the resistor
  – The ignition coil is damaged
  – Replace the ignition coil
Electrodes of spark plugs or backlash between them are made oily does not correspond to norm
Clear candles and adjust a backlash between electrodes
Spark plugs (a crack on an insulator) are damaged
Replace candles new
The order of joining of wires of a high voltage to conclusions of a cover of the distributor of ignition is broken
Attach wires as ignition 1–3–4–27. Check up, adjust the ignition moment
Wrong installation of the moment of ignition
Check up, adjust the ignition moment
The engine works unstably or глохнет idling
Wrong installation of the moment of ignition
Check up, adjust the ignition moment
The big backlash between electrodes of spark plugs
Check up, adjust a backlash between electrodes
Small backlash between breaker contacts
Adjust a backlash between contacts
The engine non-uniformly and unstably works at the big frequency of rotation of a cranked shaft
Ослабла a spring of mobile contact of the breaker
Replace contact group
The big backlash between breaker contacts
Check up, adjust a backlash between contacts
Ослабли springs грузиков a regulator of an advancing of ignition in the ignition distributor
Replace springs, check up work of a centrifugal regulator at the stand
Faults in engine work on all modes
Wires in ignition system are damaged, fastening of wires is weakened or their tips are oxidised
Check up wires and their connections, the damaged wires replace
Are polluted, oxidised, have burnt or breaker contacts are displaced
Smooth out contacts and adjust a backlash between them
Deterioration of electrodes or замасливание spark plugs, a considerable deposit; cracks on a candle insulator
Check up candles, adjust a backlash between the electrodes, the damaged candles replace
Deterioration or damage of a contact piece of coal to a cover of the distributor of ignition
Replace a contact piece of coal
Strong подгорание the central contact of a rotor of the distributor of ignition
Smooth out the central contact
Cracks, pollution or прогары in a rotor or a cover of the distributor of ignition
Check up, replace a rotor or a cover
Decrease in capacity of the condenser or breakage in it
Replace the condenser
Excessively big palpation of the platen of the distributor of ignition; the raised deterioration of the plug of the platen
Replace the ignition distributor
The engine does not develop a total power and does not possess sufficient приемистостью
Wrong installation of the moment of ignition
Check up, adjust the ignition moment
Jamming грузиков a regulator of an advancing of ignition, easing of springs грузиков
Check up, replace the damaged details
The big deterioration of the plug of mobile contact of the breaker
Check up, replace contact group
