At the ignition coil resistance of a winding is checked, whether there is no short circuit between windings and isolation breakdown on "weight". Isolation breakdown on "weight" is found out on прогару or to smelting of a plastic cover of the coil of ignition. Measurement of resistance of a winding of the coil of ignition spend an ohmmeter.

Check of the coil of ignition carry out in a following order.

2,0 litre engine:

- Switch off ignition and disconnect a high-voltage wire from the high voltage transformer;

Fig. 215. Plugs �1�, �4� and �15� on the high voltage transformer, for check of resistance of primary and secondary windings of the coil of ignition on the 2,0-litre engine

- Connect an ohmmeter between plugs �1� (plus) and �15� (minus) (fig. 215) and measure resistance of a primary winding which should make 0,5—1,2 Ohm;

- Connect an ohmmeter between plugs �15� and �4� (the central cable) and measure resistance of a secondary winding which should make 3 — 4 clod;

- If resistance does not correspond to the specified sizes it is necessary to establish the new transformer of a high voltage.

Engine VR6

It is recommended to inspect coils of ignition of engine VR6 on HUNDRED.
