Ignition Primary pattern :
This pattern is a good way to check the condition of the ignition circuits . It also uses string theory so as the firing voltage increase the burn time decreases and vice-versa.
Firing voltage: The voltage or push needed for the spark to jump the spark plug gap .
Burn voltage: Voltage needed to maintain an arc or spark between the spark plug electrodes so it can burn all of the fuel in the combustion chamber.
Burn time: The length of time in which the arc or the spark maintained , its a good indication of the state of the secondary circuit components (spark plugs , HT leads , King lead , distributor cap , rotor and secondary ignition coil )
Dwell time: The length of time in which the primary circuit is grounded (turned on) for prior to the each spark . It is to build enough magnetic field in the primary so then after collapsing it can induce a high enough voltage in the secondary windings .
