I teach high school auto shop and here is an old ignition trainer that I use. It is the old point style ignition and I still use it because the theory is still the same. It used points, which is a simple switch to make or break current to a high voltage coil.
Newer electronic systems do the same only they use solid state components instead of a mechanical switch. Students always struggle trying to understand that the spark happens when the power is removed from the coil not when power is applied..
F... Deer flies. For those of your lucky enough to live near these fellas, let me present my solution. Apply tanglefoot to hard hat while working. #NewHampshire#PestControl
