Points typically spark when they close, as the electrical contact is made, causing a sudden surge of current that can produce a spark. However, sparks can also occur when points open if the current is suddenly interrupted, leading to an arc as the contacts separate. In summary, while closing often generates more noticeable sparks, both actions can lead to sparking depending on the circuit conditions.

What do the points on a car engine do?
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.
What is a distributor shaft?
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
What is the purpose of distributor?
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.
How do you set ignition timing Briggs straton 8HP engine?
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
How do you spark verhicle without ecu?
To spark a vehicle without an ECU, you can bypass the ignition system by directly supplying voltage to the ignition coil. This involves connecting a 12V power source to the positive terminal of the coil and grounding the negative terminal, allowing it to generate a spark. Additionally, you can manually open and close the points in a traditional distributor setup to create the necessary spark timing. However, this method should be approached with caution, as it can be dangerous and may cause damage if not done correctly.
What does dwelled?
The number of degrees the breaker cam rotates from the time the breaker points close until they open again.
On a 69 corvair do the points open at top dead center or close?
They open so they can fire the cylinder when the pistion reaches TDC / Top Dead Center.
What is one main function of the condenser for engine?
To absorb voltage spikes or surges that occur when the breaker points open and close.
Why would a test light placed on the distributor side of the coil flicker when the engine is cranked?
It is normal. In order for you to create a spark, the coil has to open and close.
Why there is a spark when you on a switch with a force?
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).
Where are the breaker points and condenser connected in an ignition system on small engines?
In a small engine ignition system, the breaker points are typically connected to the ignition coil and the condenser (or capacitor) is connected in parallel with the breaker points. When the engine is running, the breaker points open and close to control the flow of current to the ignition coil, while the condenser helps to suppress electrical arcing at the points, prolonging their lifespan and improving ignition efficiency. This configuration allows for the generation of a high-voltage spark needed for combustion in the engine's cylinders.
Is there points and plugs on 1999 Chrysler Cirrus?
Spark plugs, yes. Points, no.
