3000 EXPRESS
Deteriorated cables cause a considerable voltage loss when high currents are drawn, as for starting
the engine.
NEVER USE AN OPEN FLAME IN THE BATTERY STORAGE AREA. AVOID STRIKING
SPARKS NEAR THE BATTERY. A BATTERY CAN EXPLODE IF A FLAME OR SPARK IG-
NITES THE HYDROGEN GAS THE BATTERY EMITS WHILE BEING CHARGED.
110-Volt AC Electrical System Maintenance
Periodically inspect all wiring for nicks, chafing, brittleness, improper support, etc. Examine the
shore power cord closely for cracks in the insulation and corrosion in electrical connectors.
Spraying receptacles and electrical connections with an electrical contact cleaner or a metal and
electrical protector will reduce corrosion and improve electrical continuity.
Inspect all wiring for proper support, sound insulation, and tight terminals, paying particular
attention to portable appliance cords and plugs.
The entire 110-volt circuitry, especially the shore power cord, should be seasonally tested for
proper continuity by an experienced electrician. This will detect any shorts, open wires, or ground
faults. Ground fault interrupts should be tested periodically to insure proper operation by pressing
the test/reset buttons in the center of face plate. The polarity indicator system also should be
inspected for proper operation.
The engine maintenance required on the generator is similar in many ways to the main engines. The
most important factors to the generator's longevity are proper ventilation, maintenance of the fuel
system, ignition system, cooling system, lubrication system and the AC alternator.
Maintenance schedules and procedures are outlined in your generator owner’s manual. They
should be followed exactly.
CORROSION ALLOWED TO BUILD ON THE ELECTRICAL CONNECTORS CAN CAUSE A
POOR CONNECTION RESULTING IN SHORTS, GROUND FAULTS OR POOR GROUND CON-
NECTIONS. ELECTRICAL CONNECTORS SHOULD CHECKED AT LEAST ANNUALLY AND
CLEANED AS REQUIRED. DO NOT ALLOW CORROSION TO BUILD ON CONNECTIONS.
THE AC AND DC ELECTRICAL SYSTEMS ALWAYS SHOULD BE DISCONNECTED FROM
THE POWER SOURCE BEFORE INSPECTING OR SERVICING THE SYSTEM. NEVER SER-
VICE ANY COMPONENT OF AN ELECTRICAL SYSTEM WHILE IT IS ENERGIZED.
