Electrical System
Inspect Battery Cables
Do not allow open flames or sparks near the batter -
ies. Battery fumes are highly explosive.
Sulfuric acid in batteries is a poison and could
cause severe burns. Avoid contact with skin, eyes,
and clothes. When you work around batteries, pro -
tect your eyes and face from battery fluid and ex -
plosion.
When removing the battery cables, always remove
the negative terminal first then the positive termi -
nal. This will reduce the chance of sparking.
Check the battery terminals for corrosion buildup
and tightness of connection.
Clean the cable connector and terminals if needed.
• Remove the terminal cable.
• Clean both the battery cable connector and
the battery terminal.
•
Reinstall the positive battery cable connec-
tor.
• Reinstall the negative battery cable con-
nector.
• Tighten both connectors securely.
Clean the battery. Batteries should be kept clean
at all times.
• Make sure all the battery caps are on tight.
• Make sure the vent holes in the battery
caps are kept open at all times to allow gas
to escape from inside the battery.
• Wipe the outside of the battery with a cloth
to remove dirt and grime.
• Remove the battery cables.
• Clean the cables with a wire brush.
•
Soak the cables.
• Wash the terminals in a solution of baking
soda and water.
• Rinse the cables, battery, and battery com -
partment with clean water.
