Removing-refitting ignition coils

Removing-refitting ignition coils

Proceed with the removal of the ignition coils by carrying out the following operations:

• disconnect the electrical connector;
• undo the two fixing bolts and remove the coil, extracting it from the housing.

NOTE The coil is fitted with an extension made from a silicon material with a high dielectric power inside of which there is a pressure switch with a spring loading.
Do not dismantle the two components so as not to risk losing the internal contact or getting it dirty.
In the case of replacement, it is not necessary to separate the coil from the extension because the complete coil/extension assembly is available as spares.

Checking primary circuit coil resistance

The resistance is checked by following the diagram.

Primary resistance: 0.6 ± 0.06 ohm

Removing-refitting ignition power module

Remove the ignition power module carrying out the following operations:

• disconnect the electrical input and output connectors (arrow);
• undo the two fixing bolts and remove the module.
