Where does the Spark Go in a distributor cap?
Where does the Spark Go in a distributor cap?
As the rotor rotates, its edge passes each of the plug terminals that are arranged around the inside of the cap, according to the firing order, sending the secondary voltage to the proper spark plug. The rotor edge however does not touch the plug terminals but the spark jumps when it is just opposite to it.
What causes sparks in a distributor ignition system?
That moves other distributor parts that cause the ignition coil to pulse, and sends the electricity down each spark plug wire in order. The power travels down the spark plug wires to the spark plugs and causes sparks. The sparks ignite the fuel and air in the engine cylinders. That’s it. Hopefully you found that briefer and easier to understand.
Can a bad distributor cap cause an engine to misfire?
If you’re idling at a stop sign or red light and your car seems to be shaking more than normal, that could be a sign that the rotor inside the distributor cap is letting ignition electrical pulses go to ground, and therefore the engine misfires.
How are distributor caps used in an engine?
Distributor caps are used in automobile engine to cover the distributor and its internal rotor. The rotor switches a high sparking voltage to the spark plugs so that these fire in correct sequence. The distributor cap is a prime example of a component that eventually succumbs to heat and vibration.

Is there no spark from distributor to spark plugs?
Q: No spark from distributor cap to spark plugs. Car died while driving. Wouldn’t start again. I did basic No start troubleshooting. Tested from the ignition coil to the distributor is good, from the cap itself no power. I replaced the cap, rotor, tfi, distributor itself, and the ignition coil. Same results.
What happens when the distributor cap is not on?
Car doesn’t start. When the distributor cap isn’t on tightly or is malfunctioning, the engine is unable to send the spark through the entire circuit required to move the cylinders – which ultimately make the car run.
How does the distributor rotor and cap work?
The distributor rotor and cap keep the distributor’s contents separate from the engine and keep the distributor’s working parts clean and tidy – while supporting the incredibly high volts of energy and delivering them to the appropriate spark plugs. The spark plugs utilize the spark from the distributor to ignite the fuel mixture,…
