       NOTES
At the time of preparation of the repair manual there is no information on the size of resistance of primary winding of the coil of ignition on models from 1998 to 2000 and data on check of coils of ignitions/switchboards on models since 2001.
You carry out an inspection of resistance of windings of coils of ignition on the cold engine as on the hot engine resistance will be more. Are immediately disconnected by Steklolopodjemniki.

Carry out check of coils of ignition as follows:
Check resistance of primary winding to the coil of ignition for what:
– switch off ignition and disconnect electric sockets from each coil of ignition;

Fig. 6.1. Connection of an ohmmeter (1) to contacts of the electric socket for measurement of resistance of primary winding of the coil of ignition on models from 1996 to 1998


– measure by the ohmmeter connected to contacts resistance which has to correspond to the value given in specifications, otherwise, replace the coil of ignition (fig. 6.1) – the ignition coil on models from 1996 to 1998 is installed on an arm on a partition of a motor compartment;
Check resistance of a secondary winding of the coil of ignition for what:
– switch off ignition;

Fig. 6.2. Connection of an ohmmeter (1) for measurement of resistance of a secondary winding of the coil of ignition on models from 1996 to 1998


Fig. 6.3. Connection of an ohmmeter (1) for measurement of resistance of a secondary winding of the coil of ignition on models from 1998 to 2001


– mark and disconnect high-voltage wires from ignition coils; measure by the ohmmeter connected to one contact of the electric socket and contact of a high-voltage wire resistance (fig. 6.2, 6.3) ;
– if resistance does not correspond to demanded, replace the ignition coil.
You make replacement of coils of ignition as follows:
Switch off ignition and disconnect a wire of "weight" from the rechargeable battery.
For models from 1996 to 1998 you carry out further works in the following order:
– disconnect the electric socket and a high-voltage wire from the ignition coil;
– turn out bolts and remove from a partition of a motor compartment the ignition coil together with an arm;
– turn out bolts and remove the ignition coil from an arm;
For models from 1998 to 2001 you carry out works in the following order:
– remove throttle knot from an inlet collector;
– uncover the air filter;
– mark and disconnect electric sockets from each block of coils of ignition;
– mark and disconnect wires from spark plugs;

Fig. 6.4. Coils of ignition (1) and an arm (2) models from 1998 to 2001


– turn out bolts and remove from the engine the ignition coil together with an arm (fig. 6.4) ;
– the coil of ignition fastens on an arm on the left side of a head of the block of cylinders;
– turn out bolts and remove the ignition coil from an arm.
For models since 2001 you carry out works in the following order:
remove forward section of the case of the air filter;
each block the coil the ignition/switchboard fasten one bolt.
turn out a bolt, disconnect the electric socket and, having pulled up and at the same time turning, remove the ignition/switchboard coil block from the engine.
You make installation in the sequence, the return to removal.
