Stop/start technology is more than just a switch wired to the brake pedal and starter.
Engineers have devised two strategies that can be called the “immune system” for the electrical system.
To see inductance inside the primary windings, use an amp probe placed around the positive wire for the ignition coil.
If you see carbon tracking or “flash over” on a spark plug, boot or coil, it is not normal.
The spark plug can have a yellow or orange band that is called a corona stain. This video is sponsored by Blue Streak.
You may have seen the stories about plasma or laser ignition systems that promise to give new life to the internal combustion engine. But while these ignition systems have yet to make it to market the latest ignition innovation still uses a coil and spark plug.
In this article, we touch on the features of three ignition systems, as well as advantages and disadvantages of each.
