Ignition Coil Switching Action

This test checks to see if the negative
terminal of the primary ignition coil is
getting switched ON and OFF via the
ignition module and camshaft / crank-
shaft position sensors. This switching
action is where the RPM or tach signal
originates. This test is primarily used for
a no start condition.
