IGNITION C O I L S (0.221.504.014)
The ignition is the static advance eletronic
type w i t h a single coil for each spark plug;
this solution eliminates the high tension cir-
cuit, increasing reliability and safety and de-
creasing the risk of interference due to high
tension leads and connections.
It involves a regular coil w h i c h raises the
voltage of the impulse sent to the spark
plugs: each individual coil, located in the
cylinder head, supplies a spark plug directly
without intermediate cables.
Checking ignition coil primary circuit resis-
tance
The resistance is checked by connecting an
ohmmeter to the connector external pins ( 1
and 3 ) :
