Reslt - interference!
Now the ignition switch only controls the operation of the relay which has the main power feed from the battery so any back emf from the injectors (and later the coil too) is absorbed by the battery behaving as a big capacitor. It's also a shorter run so reduces the voltage drop to the injectors and coil.
In 940s up to 96, it feeds the injectors and Lambda sensor heater. Post 96 it also feeds the coil.  |
I know why it was called that, I'm involved in EMC compliance. Its just rather silly to call a component in your design after a result of the design having a fault. From my point of view it sounds like "defective design repair part", how does that help anyone?
Fair point if I was wrong about it supplying the coil aswell, I wasn't aware of that, good to know.
