How is the rotor connected to the distributor cap?
The distributor cap and the rotor underneath the cap are very important aspects of your car’s ignition system. The spark plug wires are connected to the distributor cap; and as the rotor turns with the engine’s revolutions, it sends a signal to each spark plug wire as it passes by, sending spark to the engine’s cylinders.

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,…
How does the rotor work in an engine?
The rotor routes the energy in a specific through the spark plug wires ultimately to the engine’s cylinders in the correct firing order.
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.

When to replace distributor rotor and spark plug?
It’s also vital to take time to mark the location of the distributor, the distributor cap, spark plug wires and the rotor on the bottom of the distributor before it’s removed; and during the removal process. Failure to properly mark the wires and reinstall the new distributor cap exactly as the used one was removed can result in ignition problems.
