When closed the coil "saturates" with voltage and when the points open the coil dumps its electrical load to the spark plug. If the points open at the right time then the spark arrives at the plugs at the proper time - then the car is "in tune" So the points basically cause your car to have spark and have the spark at the right time.
the shaft that runs through the distributor. it turns on the camshaft housing to make the top of it spin which makes the points open and close, and turns the rotor to send spark to the plugs
The distributor sends a spark to the proper spark plug at the proper time. To do this, the points open and close a circuit to the coil to generate the high voltage spark. This is fed to the rotor which is rotated by the cam shaft and then sends this voltage to each of the spark plugs as the engine turns. Synchronization of this is done with a timing light which will send the spark to cylinder #1 as it comes to top dead center in the fire cycle.
well first make sure that the gap between the armature and the flywheel is about .010" then if its properly set up the breaker points will open and close creating the necessary break in the current to allow a spark to be generated by the breaker points the gap should be about .020" on most modles but check the manual for your specific modles if they open and close at the right time then it will spark different modles use different methods but if they are hooked up right then the engine will fire on time
The number of degrees the breaker cam rotates from the time the breaker points close until they open again.
They open so they can fire the cylinder when the pistion reaches TDC / Top Dead Center.
To absorb voltage spikes or surges that occur when the breaker points open and close.
It is normal. In order for you to create a spark, the coil has to open and close.
Spark plugs, yes. Points, no.
Because of the sudden interrupt to remove the supply between the contactor. so contact opened at the time air will be ionized . so the arc or spark is produce when the switch position was open (off) or close (on).
Points .017 and spark plug .035
Just use the referral code: 9Y8Z1N then close your app. Open it and download the app offering the highest amount of points. Then delete the app, re-download it and BAM the points for the app you downloaded DOUBLES.
