Ignition Coil Wiring

 

Protection when using wiring rails

Every wiring rail on the engine block should be grounded to avoid disruptions in the device caused by secondary current in the ignition coils.

   

Ignition coil wiring

In the MICT there are two types of wiring with predefined output configuration supported in the engine database for many engines:

  • Wired in straight order
  • Wired in firing order

For information on straight order wiring refer to Straight Order Wiring of the Ignition Outputs and Engine – Parameters.

For wiring in firing order, the first cylinder in the firing order is connected to the A1 output, the second to B1 (A2 for one output board), etc.

If a different wiring was implemented, the output configuration in the MICT must be adapted accordingly. Please note that the wiring cannot be checked by the software (see section Engine – Parameters).

   

Conductor cross-section for primary wiring

If you do not use a harness manufactured by MOTORTECH, the primary wiring must have a conductor cross-section of 1.5 mm².
