WARNING!
!
Larger wires and tight connections will provide longer service life for components. For high
current wires it is highly recommended that terminal blocks or soldered connections be used
with shrink tubing to protect the connections. Do not use insulation displacement
connectors (e.g. 3M
® Scotchlock type connectors). Route wiring using grommets and
sealant when passing through compartment walls. Minimize the number of splices to
reduce voltage drop. High ambient temperatures (e.g. under hood) will significantly reduce
the current carrying capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in
engine compartment. All wiring should conform to the minimum wire size and other
recommendations of the manufacturer and be protected from moving parts and hot
surfaces. Looms, grommets, cable ties, and similar installation hardware should be used to
anchor and protect all wiring.
Fuses or circuit breakers should be located as close to the power takeoff points as possible
and properly sized to protect the wiring and devices. Particular attention should be paid to
the location and method of making electrical connections and splices to protect these points
from corrosion and loss of conductivity. Ground terminations should only be made to
substantial chassis components, preferably directly to the vehicle battery.
The user should install a fuse sized to approximately 125% of the maximum Amp capacity in
the supply line to protect against short circuits. For example, a 30 Amp fuse should carry a
maximum of 24 Amps. DO NOT USE 1/4" DIAMETER GLASS FUSES AS THEY ARE NOT
SUITABLE FOR CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit breakers are
very sensitive to high temperatures and will "false trip" when mounted in hot
environments or operated close to their capacity.
