-
Never disconnect the batteries while the key switch is on and
the engine is running.
Why: This can cause electrical voltage spikes that can damage
electronic components.
-
Do not connect jumper cables while the key switch is on.
Why: This can cause electrical voltage spikes that can damage
electronic components.
-
Disconnect batteries prior to recharging (if possible)
Why: Electrical loads in the machine can slow the recharging
process. Battery chargers can cause electrical voltage spikes that
can damage electronic components.
-
Never jump start the machine with a voltage higher than the
machine is designed to operate on
Why: This can damage electronic components
-
Do not connect or disconnect electrical connectors while the
key switch is on or the machine is running.
Why: This can cause computer system errors from interrupting
a computer program while it is running and electrical voltage spikes
that are produced can damage electronic components.
-
Do not apply power or ground to any component as a test unless
specifically instructed to do so.
Why: Connecting the wrong voltage to the wrong point of an electronic
system can cause electronic component failures.
-
When welding on the machine, make sure to connect ground lead
to the parts being welded. For maximum protection disconnect all electronic
controllers before welding.
Why: The high currents associated with welding can damage wiring
harnesses that are involved in the ground path. Welding can also cause
electrical voltage spikes that can damage electronic components.
