7.2.5. Check of the coil of ignition (C14NZ engine)

The coil of ignition is located in a motive compartment, at a forward frame at the left. It can be checked an ohmmeter.


 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Separate contact 4 (A) and the multicontact socket(s) of the coil of ignition.

Contacts of the coil of ignition

  1. Check connection of the coil of ignition with weight. For this purpose by means of an ohmmeter make sure of lack of conductivity between the plug 15 and weight (1).

Checks of the coil of ignition

  1. Check resistance of primary winding. For this purpose include an ohmmeter between plugs 1 and 15 (2). The ohmmeter has to show 0.45 Ohms.
  2. Check resistance of a secondary winding. For this purpose include an ohmmeter between plugs 1 and 4 (3). The ohmmeter has to show 5 ÷ 7 kOhm.
  3. Connect an electrical wiring to the coil of ignition and the battery.

Replace the ignition coil only to the removed coil corresponding according to characteristics. Otherwise it is possible to damage the control unit of ignition.
