Disconnect
The battery cables or the batteries should not be

tery cover should be removed before any servic-
ing is attempted.
Removing the battery cables or the batteries with
the cover in place may cause a battery explosion
resulting in personal injury.
1. Turn the start switch to the OFF position. Turn the
ignition switch (if equipped) to the OFF position
and remove the key and all electrical loads.
Note: After the engine has stopped, allow 2 minutes
in order for the diesel exhaust fluid lines to be purged
before disconnecting the power.
2. Disconnect the negative battery terminal. Ensure
that the cable cannot contact the terminal. When
four 12 V batteries are involved, 2 negative
connections must be disconnected.
3. Remove the positive connection.
4. Clean all disconnected connection and battery
terminals.
5. Use a fine grade of sandpaper to clean the
terminals and the cable clamps. Clean the items
until the surfaces are bright or shiny. DO NOT
remove material excessively. Excessive removal
of material can cause the clamps to fit incorrectly.
Coat the clamps and the terminals with a suitable
silicone lubricant or petroleum jelly.
6. Tape the cable connections in order to help
prevent accidental starting.
7. Proceed with necessary system repairs.
8. In order to connect the battery, connect the
