MaintenanceMaintaining the Electrical System
• Check to ensure the regulator is correctly mounted
and that the mounting bolts are tight.
• Check the regulator for external damage.
Mixer and Throttle Control Device
The mixer and throttle body components have been
specifically designed to meet the engine’s fuel system
requirements.
A dirty air filter can significantly alter the mixer
performance. Ensure that the air filter is clean. When
inspecting the mixer and throttle body, check the
following:
• Check all the fittings for leaks.
• Ensure the mixer and throttle body are securely
mounted.
• Inspect and clean the air filter element according
to the recommended service intervals listed in the
Maintenance Schedule section.
• Inspect the air inlet hose connection and clamp.
Inspect the hose for cracking, splitting, or chafing.
Replace the hose as necessary.
• Check for leaks at the throttle body and intake
manifold.
Alarms (Service Code Detection
System)
The generator runs for long periods of time without an
operator present. Therefore, the system features sensors
that automatically shut down the generator in potentially
damaging conditions, such as low oil pressure, high
temperature, overspeed, and other conditions.
Service alarm descriptions appear in the digital display of
the generator’s controller.
See the Alarms section of the separate online manual
titled Operation Instructions GC1030 SERIES GENSET
Controller (part number 80086364) for details on service
alarm descriptions.
Acknowledging and Resetting the
Alarms (Service Code Detection
System)
Push the up and down arrows (A) simultaneously to reset
the alarm.

Maintaining the Electrical System
Wiring and Connections
The generator’s electrical system incorporates computers
to control various components. The electrical system
connectors and grounds require good connections.
When inspecting the electrical system, check the
following:
• Check the positive (+) and the negative (-) battery
cables for corrosion, rubbing, chafing, and burning.
Ensure that both ends have tight connections.
• Check the battery for cracks or damage to the case.
Replace the battery if necessary.
• Inspect the engine wire harness for rubbing, chafing,
pinching, burning, and cracking and for breaks in the
wiring.
• Ensure that the engine harness connectors are
correctly locked in.
• Inspect the ignition coil wire for hardening, cracking,
chafing, burning, separation, and split boot covers.
• Inspect the spark plug wires for hardening, cracking,
chafing, and burning. Check them for separation and
split boot covers.
