Ignition Distributor
The distributor sends ignition high voltage to each cylinder in older engines.
What is Ignition Distributor?
A rotor turns inside a cap with contacts. Modern engines use coil-on-plug ignition instead. Timing was adjusted by rotating the distributor. Breaker points in very old distributors needed regular adjustment, while electronic ignition replaced them with sensors. Classic car owners often fit electronic ignition kits for reliability. Checking the cap for cracks and carbon tracking is a quick test.
How it works
The rotor passes each contact and directs the spark.
Why it matters for your car
Worn caps and rotors cause misfires. Moisture inside the cap can stop the engine.
