This is page 22 of a Ford Electrical & Vacuum Troubleshooting Manual (EVTM) titled "Charge/Power Distribution (Diesel)." It is a wiring diagram showing how battery power (circuits 37 Y and 38 BK/O) feeds the ignition switch and interior fuse panel on a diesel truck. The ignition switch is drawn with its ACCY/LOCK/OFF/RUN/START positions and terminals (I1, I2, A2, ST, A1, P2, P1), with a note referring to page 124 for switch terminal identification. Switched outputs include circuit 16 R/LG to the diesel warning indicators, 32 R/LB to the diesel start/glow plug control, 297 BK/LG to the windshield wiper/washer, 41 BK/LB and 977 P/W to diesel indicators. Fuse links V and U (20 gauge blue) feed the diesel start/glow plug control (30 R/LG) and fuel line heater (34 DB). The fuse panel section documents fuse positions and amperages: 18 (15A), 15 (10A), 10 (5A), 9 (30A), 5 (15A), 11 (15A), 14 (30A), 6 (15A), 17 (20A), 1 (15A), 12 (30A), 4 (15A), 8 (15A), and 16 (30A), with output circuit numbers, wire colors, and the systems they power (heater, turn signals, power windows, speed control, anti-lock brakes, stop/hazard lamps, power door locks, horn/cigar lighter, etc.) with EVTM page cross-references.
