Check of serviceability and replacement of the coil of ignition
Check
|
Disconnect a negative wire from the battery.
|
If the radio tape recorder in your car is equipped by a security code before to disconnect from the battery a negative wire make sure that the given code know. |
Mark wires and plugs by means of the numbered slices of an adhesive tape, then disconnect from the coil of a wire of a primary contour and ВВ a wire. Disconnect assemblage of an arm of the coil and remove it in gathering with the coil. Clear outside the case of the coil and check up it on presence of cracks and other obvious damages.
Smooth out primary plugs of the coil and check up ВВ the coil plug on presence of traces of corrosion. In case of detection of those remove them by means of a wire brush.
Measure resistance of a primary winding of the coil, having connected ohmmeter wires to positive and negative plugs. Compare results of measurements to the data of Specifications.
|
Resistance check between plugs of a primary winding of the coil of ignition - the coil should be taken from an impellent compartment and is transferred on a workbench that gives a guarantee of qualitative connection to its plugs of wires of an ohmmeter.
|
Measure resistance of a secondary winding of the coil, having connected one wire of an ohmmeter to any of plugs of a primary winding, and the second - to big central (ВВ) to the coil plug. Compare result to the data of Specifications.
|
Resistance measurement between positive ВВ (secondary) coil plugs.
|
Really taking place values depending on coil temperature can differ slightly from resulted in Specifications (characteristic for temperature nearby 21 ).
If the coil has not passed check, replace it.

Replacement
|
Disconnect a negative wire from the battery.
|
If the radio tape recorder in your car is equipped by a security code before to disconnect from the battery a negative wire make sure that the given code know. |
Uncover the distributor (the Head of Adjustment and routine maintenance). Give screws and disconnect wires from primary plugs.
Give two screws and take the coil from an impellent compartment.
|
The coil of ignition of the engine in volume of 4.0 l.
|
|
Removal of the coil of ignition from the engine in volume of 5.2 l. |
Installation make upside-down.
