7.1.4. Check of coils of ignition

Fig. 7.2. Measurement of resistance of primary winding of the coil of ignition


Measure resistance of primary winding of the coil between conclusions of 1 and 2 C18-2 and S68-1 sockets (the ignition coil for cylinders No. 1 and No. 4) coils of ignition and between conclusions of 1 and 2 C18-1 and S68-2 sockets (the ignition coil for cylinders No. 2 and No. 3) coils of ignition (fig. 7.2).
Nominal rate: 0,5 ±0,05 Ohms.

Fig. 7.3. Measurement of resistance of a secondary winding of the coil of ignition


Measure resistance of a secondary winding between conclusions of high voltage for cylinders No. 1 and No. 4, and also for cylinders No. 2 and No. 3 (fig. 7.3).
Nominal rate: 12,1 ±1,8 kOhm.

ATTENTION
Before measurement of resistance of a secondary winding be convinced that the socket of the coil of ignition is disconnected.
