Ford manual charging-system diagram plus component location/connector-description table (alternator, voltage regulator, starter relay, splices) and the alternator-regulator jumper-wire test setup.
Part of 1978-1979 Ford Bronco Service Procedures
This page (page 9 of a multi-page Ford service reference set) illustrates the charging/starting system components of a late-1970s Ford truck. A pictorial diagram shows the alternator, alternator regulator (a Motorcraft electronic regulator), starter relay, and Motorcraft battery, with dark blue lines representing factory wiring and red lines showing test connections: a jumper wire installed at a connector (with one lead going 'To Alternator Warning Light') and a voltmeter connected across the battery terminals for a charging system test. Below the illustration is a component location legend listing the Accessory Safety Relay, Alternator Voltage Regulator, and Choke Heater (on the RH side of the carburetor), plus connectors C205, C206, C208, C210, and C212 with their physical locations (RH radiator support, RH fender apron near the steering motor relay, rear of instrument cluster, rear fender apron behind the battery, engine compartment center of dash panel) and connector descriptions (terminal counts, shapes, and colors). It also lists numerous wiring splices (S201-S1202) with their locations, such as near the starter motor relay, fuse panel, ignition switch, blower motor resistor, and junction block. Readers can use this page to locate charging-circuit connectors and splices and to see the voltmeter/jumper-wire test hookup.
