Checking ignition coils
| Fig. 7.2. Measuring the resistance of the primary winding of the ignition coil
|
Measure the resistance of the primary winding of the coil between terminals 1 and 2 connectors S18-2 and S68-1 (ignition coil for cylinders ?��1 and ?��4) ignition coils and between terminals 1 and 2 connectors S18-1 and S68-2 (ignition coil for cylinders ?��2 and ?��3) ignition coil (Fig. 7.2). Nominal value: 0,5 ?� 0,05 Ohm.
| Fig. 7.3. Measuring the resistance of the secondary winding of the ignition coil
|
Measure the impedance between the terminals of the secondary winding high voltage and cylinders ?��1 ?��4, as well as cylinders and ?��2 ?��3 (Fig. 7.3). Nominal value: 12,1 ?� 1,8 kW.
ATTENTION Before measuring the resistance of the secondary winding, make sure that the connector of the ignition coil is disconnected. |
