Ignition Components
It is attached to the engine and is used to measure the ignition timing.
Timing Scale
This carries the high voltage current to the spark plug gap.
Center Electrode
This opens the point assembly in an MBI application
Cam
This component is what creates the voltage for CDI system.
Charge Coil/Stator Assembly
There are two main types of ignition systems one is Magneto. What is its counterpart.
Battery Ignition
This component has two different layers of copper windings. (primary and secondary)
Ignition Coil
This is an aluminum-oxide ceramic material.
Insulator
What is the initial feeler gage setting when installing a new set of points.
.020"
This is what creates the voltage for the SCR switch.
Trigger Coil
If you increase the ignition timing several degrees what would happen to the internal engine temperature.
Goes up.
This component will be disconnected from the secondary lead for testing.
Spark plug cap
This effects how well the insulator cools the tip of the electrode.
Heat Range
When do the breaker points fire the spark plug.
When they open
This is roughly the ignition timing when starting a engine that utilizes CDI system.
8 - 11 degrees
If you increase boost pressure on a supercharged engines what should you do with your sparkplug heat range?
Decrease, Lower
This has to be take into consideration when you make engine timing changes and coincides with the air fuel ratio.
Spark Plug
If the spark plug falls below 700 degrees what could happen to the spark plug?
Spark Plug fouling or Shorting
What will happen to the points if the condenser is bad?
Arching across points, burned points
This is roughly the voltage stored in an capacitor.
175-300 volts
What is the term for a spark that is fired on the exhaust stroke?
Waste Spark
This is used in CDI systems to release the voltage from the capacitator.
Silicon Controlled Rectifier
If this is too long it could damage the piston.
Spark Plug Reach
This is the term used to describe how long the points are closed.
Dwell angle
What is used to change convert the voltage in an CDI system to charge the Capacitator.
Diode
In a battery operated ignition system. When you turn the key off what happens to the ignition coil.
De-energize / No power to coil primary / Will not spark.
