DISTRIBUTOR CAP & ROTOR
DISTRIBUTOR CAPS AND ROTORS ARE RESPONSIBLE FOR PASSING THE VOLTAGE FROM THE IGNITION COILS TO THE ENGINE'S CYLINDERS IN ORDER TO IGNITE THE FUEL-AIR MIXTURE INSIDE AND POWER THE ENGINE. THE COIL CONNECTS DIRECTLY TO THE ROTOR, AND THE ROTOR SPINS INSIDE THE DISTRIBUTOR CAP. WHEN THE ROTOR'S TIP PASSES A CONTACT ON THE CYLINDER, A HIGH-VOLTAGE PULSE TRAVELS FROM THE COIL TO THE CYLINDER VIA THE ROTOR. THAT PULSE JUMPS THE LITTLE GAP BETWEEN CONTACT AND ROTOR AND MOVES ON TO THE SPARK PLUG WIRE, EVENTUALLY IGNITING THE SPARK PLUG ON THE CYLINDER. BECAUSE OF ALL THE HIGH-VOLTAGE ACTIVITY, THE ROTOR AND CAP HAVE TO BE REPLACED RELATIVELY FREQUENTLY. THEY WEAR OUT EASILY.
SPARK PLUG WIRES
SPARK PLUG WIRES (ALSO CALLED HIGH TENSION LEADS) ARE ELECTRICAL CABLES USED BY OLDER INTERNAL COMBUSTION ENGINES TO TRANSMIT HIGH-VOLTAGE ELECTRICITY FROM THE DISTRIBUTOR TO THE SPARK PLUGS . TENSION IN THIS INSTANCE IS A SYNONYM FOR VOLTAGE. HIGH TENSION MAY ALSO BE REFERRED TO AS HT.
