As a simple example, a typical ignition coil may have a secondary winding resistance of 4000 ohms and a secondary current of 400 milliamperes.
42.
A useful feature was an'emergency starting'key position for times when the battery was flat to connect the alternator current directly to the ignition coils.
43.
The basic actuators controlled by the SBEC's outputs included the fuel injectors, ignition coil and pickup, and the Idle Air Control ( IAC ) valve.
44.
In General Motors high energy ignition ( HEI ) systems there is no central post and the ignition coil sits on top of the distributor.
45.
The computer will send a signal to the ignition coil at the indicated time in the timing map in order to fire the spark plug.
46.
It builds up to the right value in the ignition exciters ( similar to automotive ignition coils ) and is then released as a high energy spark.
47.
This eliminated the problem of burned and worn points, and provided a hotter spark because of the faster voltage rise and collapse time in the ignition coil.
48.
As this is a non-contacting device and the ignition coil is controlled by solid state electronics, a great amount of maintenance in point adjustment and replacement was eliminated.
49.
Audi said its reliability figures " have been temporarily low due to an exceptional and unique ignition coil problem which was rectified for production of cars during 2003.
50.
The most obvious change to the system was the introduction of ignition coils with built in ignitors, therefore the coil ignitor that was on previous models was not used.
