2. During fault finding, it will often be necessary to un-
couple connectors for inspection, or to provide ac-
cess for testing. When using the combine on-board
diagnostics, uncoupling connectors as directed in the
fault finding procedures will often be necessary to
locate the source of the fault. Unless specifically
noted, connectors should not be back-probed using
test spoons or other tools, to prevent damage to the
connector and wire seals.
Never couple or uncouple electrical connectors while
the engine is running, to prevent machine damage and
personal injury due to electrical shock. Z018
To avoid personal injury, never attempt to access elec-
trical connectors under the cab while the engine is
running. Accidental contact with the straw elevator
angle sensor or inappropriate access to the electrical
circuits to the modules may cause the straw elevator
to move unexpectedly, resulting in personal injury or
death. Z028
3. If it is found necessary to clean the connectors a
contact spray should be used. DO NOT USE ANY
OTHER METHOD FOR CLEANING TERMINALS.
Do not use a cleaner that contains Trichloro-ethy-
lene, this solvent will damage the plastic body of the
connector. It is preferable to use a cleaner with a
Freon T.F. base.
