This is a scanned page (23-01-2) from a Ford factory service manual section titled 'General Ignition Service.' It contains Figure 1, a labeled pictorial diagram of the Duraspark II Ignition System, showing all major components and their wiring interconnections. Labeled components include the ignition switch (with RUN, START, and START BYPASS circuit callouts), ballast resistor, ignition coil (with BAT and TACH TEST terminals noted), starter relay, battery, distributor, distributor cap, rotor, adapter, spark plug, and ignition module. The diagram is identified by reference number B4097-2A. A reader can learn the overall layout of the Duraspark II ignition system: how battery power flows through the starter relay and ignition switch, how the run circuit passes through the ballast resistor to the coil while the start bypass circuit feeds the coil directly during cranking, and how the ignition module connects to the distributor and coil. It also identifies the coil's TACH TEST terminal location and shows the distributor cap, rotor, and adapter assembly relationship. Faint mirror-image bleed-through from the reverse side (the Group 23 / Section 23-01 index page) is visible but largely unreadable.

Frequently asked questions

What components are shown in the Duraspark II ignition system diagram?
The diagram labels the ignition switch, ballast resistor, coil, starter relay, battery, distributor, distributor cap, rotor, adapter, spark plug, and ignition module.
How does power reach the coil in the Duraspark II system?
Per the diagram, the RUN circuit from the ignition switch passes through a ballast resistor to the coil, while a separate START BYPASS circuit feeds the coil directly during cranking. The coil's BAT terminal is labeled.
Where is the tach test connection on a Duraspark II ignition?
The diagram shows a TACH TEST terminal located on the ignition coil.
What figure and page is this from?
It is Figure 1, 'Duraspark II Ignition System,' on page 23-01-2 of the 'General Ignition Service' section, diagram reference B4097-2A.
