That's harder to justify when your classic muscle car won ... simple on/off switch, the ignition points, to provide properly timed pulses of 12-volt electricity to the ignition coil.

The ignition coil ... spark-producer. Switch the meter's resistance range to the 20K-ohm setting, and attach the negative (black) meter lead to the center terminal of the coil.

The juncture between the two systems is the ignition coil. The primary system carries the 12-volt DC current from the battery through the ignition switch ... the positive terminal and loops ...

I used the up position for each switch to represent a 1 and the down position to represent a zero, then wired the "run" sequence (which sent power to the ignition coil) to be the five-digit binary ...

Your car’s ignition coil transforms battery voltage to many ... The spark-plug wire also might have had a corroded end terminal or torn conductor. Should you repair the offending spark-plug ...
