RACEWAY: Your Wells Cargo
Trailer may be equipped with a
two-piece, molded snap-a-part
wiring Raceway mounted inside, at
the roof line. The Power Cable
enters the Raceway at the front
wall, and supplies connection for all
internal and external 12 Volt
Lighting. There are NO under
carriage splices or taps in the
lighting circuits. If you wish to add
other lighting in the future, all
connections can be made within the
snap-a-part Raceway.
TROUBLE SHOOTING: The
Raceway provides easy access for
trouble shooting should you develop
any problems. Circuits can be
individually connected or discon-
nected for testing purposes.
Example: Should a Tail Light Fuse
blow and continues to blow,
disconnect all Brown wires from the
Main Cable. Replace Fuse. Recon-
nect one Brown wire at a time until
Fuse blows again. This last wire,
then, is the problem. Disconnect it.
Reconnect all other wires, and check
for lights that are not lit .The
problem will be a malfunctioning
fixture, or a grounded wiring. Use
the same procedure to trouble
shoot any other circuit. Some trailer
models are not equipped with the
Raceway. Instead, they have a
Junction Box located at the interior,
road side rear. The main 12V power
cable feeds through the road side
Frame Rail and through the Rear
Corner Post to the Junction Box.
All distribution for 12V, interior and
exterior lighting feeds through the
Junction Box.
All checks and trouble shooting can
be done at the Junction Box. There
are no under carriage splices or taps.
A NOTE ABOUT WIRING YOUR
TOW VEHICLE:
The electrical
system for your trailer is protected
by the circuit protection system in
your tow vehicle. When “hot lines”
are added for brakes and accesso-
ries, this wiring should be fused in
the tow vehicle. Never use existing
tow vehicle wiring for these lines.
Run new wiring directly to the Plus
(+) side of the tow vehicle battery.
Never use circuit breakers for circuit
protection when installing these
lines. Use 12 gage wire (minimum)
for both the brake and accessory
wires. Do not exceed a 30 amp fuse
on the brake line and a 20 amp fuse
on the accessory line.
TOW VEHICLES (Foreign
makes):
Most foreign made tow
vehicles have amber turn signals
with separate brake and turn signal
wiring. In order for the trailer’s
lights to work properly, one must
install a special tail light converter
to the tow vehicle. This converter
allows the different wiring configu-
rations of the tow vehicle and
trailer to be compatible. Most RV
and trailer parts supply stores carry
this special converter.
