Electrical System Maintenance

Wiring and Connections

The generator 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, burning, and
make sure there are tight connections at both ends.
• Check the battery for cracks or damage to the case.
Replace as necessary.
• Inspect the engine wire harness for rubbing, chafing,
pinching, burning, and cracks or breaks in the wiring.
• Make sure 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, burning, separation, and split boot covers.
• Replace the spark plugs at the required intervals listed
in the maintenance chart.
• Make sure that all electrical components are securely
mounted to the engine or chassis.
• Make sure that any additional electrical services
installed by the owner are correctly installed in the
system.
Servicing the Battery
Servicing of the batteries is to be performed or supervised
by personnel knowledgeable of batteries and the required
precautions. Keep unauthorized personnel away from the
batteries.
WARNING
Battery electrolyte fluid contains acid and is extremely
caustic. Contact with battery contents could cause severe
chemical burns.
• DO NOT open or mutilate the battery
• Wear protective goggles, rubber apron, rubber boots
and rubber gloves.
• Immediately wash electrolyte from skin with water.
• If electrolyte contacts eyes, immediately flush with water
and seek medical attention.
• Spilled electrolyte is to be washed down with an acid
neutralizing agent.
WARNING
Storage batteries give off explosive hydrogen gas during
recharging. Slightest spark could ignite hydrogen and cause
explosion, resulting in death or serious injury.
• DO NOT dispose of battery in a fire. Recycle battery.
• DO NOT allow any open flame, spark, heat, or lit
cigarette during and for several minutes after charging a
battery.
WARNING
A battery's high short circuit current could result in serious
injury.
• Remove watches, rings, or other metal objects.
• Use tools having insulated handles.
• Disconnect charging source prior to connecting or
disconnecting battery terminals.
• Do not lay tools or metal parts on top of batteries.
• Disconnect the negative (-) cable at the battery during
installation and maintenance.
