Typical Turn Signal System Wiring Diagram - Flasher & Stop Light Switch Circuit

This document is a scanned reference page titled "Typical Turn Signal Systems," showing two side-by-side schematic wiring diagrams of a generic automotive turn signal circuit. Each diagram depicts the front parking (turn signal) lights, a flasher unit, a rotary turn-signal switch with a brake light bar, the stop light switch, and the rear stop lights, with ground symbols and interconnecting wiring. The left diagram appears to show the circuit at rest; the right diagram shows the system in operation, with one front lamp and one rear lamp drawn illuminated (radiating lines) and turn-signal indicator bulbs sketched in. A previous owner has added handwritten study notes identifying the "turn signal bulbs," the "turn signal indicator bulb," a feed wire noted as coming from the ignition switch, and the brake light switch. A partially visible caption at the bottom begins to explain that a turn signal system consists of four or more bulbs, a flasher unit, and a stop lamp switch, but the rest is cut off. The page is a generic instructional/training diagram rather than a model-specific Ford wiring diagram; it contains no fuse ratings, wire color codes, part numbers, or year/model applicability. It was uploaded to a 1996 Ford F-150 gallery, likely as reference material for diagnosing turn signal or brake light wiring.
