This page, titled "Power Distribution," is from a Ford truck electrical reference set (uploaded as part of a 1979 Bronco/F100-F350 document series). It covers the charging system and the ignition/starting system. The page consists of a single large isometric cutaway illustration of a Ford pickup truck with the power distribution wiring routed in red overlay. Labeled components and their approximate physical locations include: the battery and auxiliary battery with their chassis grounds, starter motor relay, voltage regulator, radio noise capacitor, starter motor, alternator, ignition coil, distributor, breakerless ignition module, accessory relay, fuse panel, ignition switch, headlight switch, and the neutral start switch (automatic transmission only). Wiring connectors and splices are identified by number: C205, C206, C322, C323, C321, C1015, and splice S303. A reader can use this diagram to locate charging and ignition/starting system components and their harness connectors on the vehicle, and to understand how power is distributed from the batteries through the starter relay, regulator, ignition switch, and fuse panel. The page is numbered 9 in the source document.
