Distributor Cap And Rotor Arm
The distributor cap and rotor arm send high-voltage current from the ignition coil to each spark plug in turn.
What is Distributor Cap And Rotor Arm?
They are wear parts on engines with a distributor. Cracks and tracking marks cause misfires. Damp can cause starting problems. Clean the inside of the cap and check the carbon brush.
How it works
The rotor spins with the distributor shaft and passes the spark to each terminal inside the cap.
Why it matters for your car
Replace cap and rotor together when worn. Fit leads in the correct firing order.
