Ford F-150 Charging & Starting Wiring Diagram (With Gauges) - Ammeter, Alternator

This document is a hand-drawn style wiring diagram titled "With Gauges," showing the charging and starting circuit for a Ford truck equipped with gauges (ammeter) rather than warning lights. It illustrates the battery (with negative lead going to engine ground or starter mounting bolt), the starter solenoid with its S and I terminals (the I terminal feeding the coil start circuit via a Red/Blue wire), and the starter motor with its mounting bolts. A Black/Red fuse link runs from the solenoid to a splice, which feeds the alternator B terminal (Red/Orange with a SHUNT and Yellow/Black wire through the AMMETER), and the ignition switch B+ terminals via Black/Yellow wiring. The alternator (ALT) has B, S, and F terminals, with the F terminal connected to the voltage regulator (terminals F, S, A, I) and a capacitor. A White/Black wire runs to the choke. The diagram distinguishes routing for automatic transmissions (through the NSS — neutral safety switch) versus manual transmissions, both connecting to the ignition switch S terminal. A Green/Red wire connects the voltage regulator circuit to the ignition switch R terminal. Wire colors labeled include Black/Red fuse link, Red/Blue, Red/Orange, Yellow/Black, Black/Yellow, White/Black, and Green/Red.
