The lights and wiring system on equipped Demco Side Dump truck boxes meet or
exceed all federal and state requirements in effect at the time of manufacture. Wherever
required by law, lights and reflectors are marked by the manufacturer to indicate the
appropriate specifications with which each complies.
For optimum performance and long life from the truck box's lights and wiring, follow this
inspection procedure:
•
Clean all reflectors and lights. See that all lights burn properly. Replace all burned
out lights and broken reflectors. Factory approved replacement parts should be
used, and replacement bulbs of equal candle power should be used for safety.
•
WARNING! Use only a 12 volt DC battery for checking lights. Never use battery
chargers or transformers.
•
Inspect all wiring to see that it is not frayed, and that it is properly supported and
protected, with all connections tight. Be certain that the cable is supported so that it
cannot be pinched. Keep the 7-way plug on the light cable and the 7-way connector
on the side dump free of corrosion.
•
Never replace fuses or breakers with metal foil or other devices.
•
A decal is located near the 7-way connector. You may trace individual electrical
circuits by the wire colors indicated. Refer to the schematic drawing and the decal
for conductor number and wire colors.
