ELECTRICAL WIRING
WARNING:
Do not attempt to inspect or
repair the engine or generator wiring while the
unit is running. Repairs to the generator AC
wiring
should
be
made
by
a
qualified
electrician.
Always disconnect
the
battery
positive
(+)
cable
when
inspecting or
repairing the electrical system.
The electrical system should be inspected every 6 months or
every 500 hours of operation – whichever comes first.
Loose Connections:
When inspecting the electrical system, verify that all
connections are tight. Look for any discoloration of
terminals or wires which may indicate a loose connection
that is running hot. Check for any corrosion that may
cause a bad connection or excessive heat. Loose or badly
corroded terminals and connectors should be replaced.
Damaged Wiring:
Make sure that no wires are contacting hot surfaces or
sharp edges. Inspect the wires where they exit the
harness to assure that they have not been abraded,
corroded or otherwise damaged. The wiring harness should
be securely supported on the engine to prevent abrasion.
Damaged wiring should be replaced – always use wire of
the same type and size.
Excessive Dirt/Oil Build-up:
In addition to causing the generator and/or engine to
run hot, excessive dirt and oil build-up reduces the
efficiency of electrical connections. Over time, oil and
“road grime” build-up can be detrimental to the life of
the electrical system. Keeping the electrical components
and wiring clean and free of oil and dirt is important in
order to maximize the life of the electrical system. Generally,
a periodic wipe-down with a rag is all it takes to keep
things clean. Avoid using strong cleaning agents on
electrical components… although very effective, it has
been found that many popular cleaners lead to
corrosion in electrical components. Most importantly, do
not “pressure wash” or spray the generator. The generator
end is designed to contend with incidental levels of
moisture normally seen in most installations, but
excessive moisture entering the generator end during a
“spray-down” can lead to damage and catastrophic
generator failure.
