Ignition Coil, Circuit Diagram
Since the secondary winding is switched in series with both spark plugs, it has the effect of an open circuit (e.g.: on the spark plug connector) on
both ignition sparks.
The resistance of the secondary winding must be checked between both high-voltage connections:
Nominal value: 5.2 - 8.5 kohms
Resistance of primary winding between connection 1 and 15:
Nominal value: 0.3 - 0.4 Ohms
Advantages of static high-voltage distribution:
-
Reduced electromagnetic noise level (no open sparks),
-
No rotating parts,
-
Noise reduction,
-
Fewer high-voltage connections.
Location of Ignition Coils and Distribution of High-voltage
Ignition Coils (T1/1, T1/2, T1/3)
The ignition coils are located on the valve cover. Each ignition coil provides high-voltage simultaneously to two spark plugs.
