Yes, ignition has two circuits. The primary is 12 volt and includes the
ignition switch, battery, voltage, condensor, points, etc. Once energized

the primary system, the coil INDUCES a secondary voltage of maybe 25,000
volts. The big, fat wires are a secondary circuit which is induced by the
primary circuit. When the points open, the primary circuit stops. At

instant, the secondary circuit collapses with a big whack of voltage

the secondary wire set to the spark plugs. There is a little more
engineering in there, but that's the basic. AND, when secondary wires get
aged at all, they bleed off invisible amounts of their voltage all over

place.
