Inspection, Maintenance and Adjustment
ELECTRICAL SYSTEM
Check Battery Condition
1. In colder weather a greater drain is placed on the
batteries when they are used for the preheat cycle and
when starting a cold engine. Battery performance
decreases as the temperature gets lower.
2. In extremely cold weather, remove the batteries at
night and move them to a warm location. This will help
to keep them at a higher power level.
3. Inspection of battery electrolyte level.
NOTE:
The battery installed at the factory is a
Maintenance Free (MF) type. Electrolyte under
normal conditions should remain at its proper
level.
WARNING!
Before starting any battery service work, make sure to
shut the engine off and turn the starter switch to the "I"
(OFF) position.
The batteries create hydrogen gas. An explosion hazard
exists, particularly with a deeply discharged battery.
Make sure that open flames, burning objects or sparks
are kept away from the battery compartment.
Battery electrolyte is diluted sulfuric acid. Take extreme
caution when handling the batteries. The electrolyte can
cause severe chemical burns. If any electrolyte gets on
your clothing or skin, wash it off immediately with large
quantities of water. If the electrolyte gets into your eyes,
flush them immediately with a large quantity of water
and contact a doctor at once.
When installing a battery, wear safety glasses at all
times.
When removing a battery, remove the negative (-) or
ground terminal first, and then the positive (+) terminal.
This will prevent sparks or arcing that could cause an
explosion. When installing a battery, connect the
positive terminal first and then the negative terminal.
Make sure to fully tighten the terminal clamps.
