Electrical System
WIRING HARNESSES, JUNCTIONS, AND CONNECTORS
The wiring harnesses supply electrical current to the various systems of the coach. The weatherproof
connectors, plastic lock connectors, junction blocks, and connecting wires are shown in the applicable
wiring diagrams in the Electrical Schematics Manual . The circuit breaker electrical schematic therein
lists each circuit breaker number, its amperage rating, its current source, its function, and a wiring dia-
gram reference.
All wiring must be securely installed to prevent chafing or cutting which
could result in a short circuit or a potential fire.
Road de-icing sprays such as magnesium chloride and calcium chloride
can cause the deterioration of wiring systems. These chemicals can wick
into connection points and eat away at copper wiring. Never probe
through insulation when checking for electrical continuity. Never splice
into wiring even with shrink tubing to reseal. Always use dielectric
grease when opening and resealing plugs and junction boxes.
Wire Sizes and Colors
Each wire in the electrical system is of a specific size
as defined in the electrical schematics. When replacing
a wire, the correct size must be used. Never replace a
wire with one of a smaller size. Wire color abbrevia-
tions are given in the table at right.
The insulation on each wire is distinctly colored and
patterned to assist in tracing circuits and making con-
nections. The wire size and color shown on the dia-
grams are arranged so that the wire size is given first,
followed by the basic wire color. If the wire has a tracer
pattern, the basic wire color is followed by a slash (/)
and the tracer color. For example, 14 YEL/WHT indi -
cates a 14 gauge yellow wire with a white tracer pat -
tern.
