Default Re: Primary Terminal in Distributor?

Primary refers to the wiring that carries battery voltage. Secondary refers to the higher Voltage - lower amperage that the ignition coil and condenser produces. So the primary wire referred to here is the wire from the dash to the dist. body inside the armored cable. Also note that pri. wires have less insulation than secondary wires. Secondary wires, because of the high voltage can JUMP to ground.
