110V/220V Split-Phase Wiring Diagram - Black, White & Red Wire Voltages

This document is a simple color diagram illustrating the voltage relationships in a split-phase electrical system using three conductors. Three horizontal bars represent the wires: a black bar labeled "110+ Black" at the top, a white bar labeled "0 White" in the middle, and a red/orange bar labeled "110- Red" at the bottom. Double-headed arrows show the potential differences between conductors: 110 volts between the Black wire and the White (neutral) wire, 110 volts between the White wire and the Red wire, and 220 volts measured directly between the Black and Red wires. A reader can learn from this diagram that two 110-volt legs of opposite polarity relative to a common neutral (White, at 0 volts) combine to provide 220 volts across the two hot legs (Black and Red), while either hot leg to neutral yields 110 volts. The diagram contains no vehicle-specific information, part numbers, fuse data, or connector details; it is a general electrical reference showing how 110V and 220V are derived from the same three-wire system. It was uploaded to a 1990 Ford Bronco gallery but is generic electrical reference material rather than automotive wiring.
