Electrical Safety
CAUTION
Use caution when performing any
maintenance on the electrical system. This
includes changing bulbs, switches, etc.,
handling circuit breakers, batteries, etc. Pay
attention to replacement parts listed. NEVER
attempt to replace a part with a part number
that has not been recommende
d.
Replacement part numbers and descriptions
are listed in your parts catalog.
Keep all sparks and flames away from
batteries, as the gas given off by electrolytes is
explosive. To avoid sparks, connect the
ground cable last and disconnect it first. To
avoid shocks and burns, disconnect battery
ground cable before servicing any part of
electrical system or when removing batteries.
Basic Electrical Component Handling
Precautions for Vehicles Equipped with Computer Controlled Systems
Precaution Reason
NEVER
disconnect the batteries while the
key switch is on and the engine is running.
Can cause electrical voltage spikes that can
damage electronic components.
Do NOT
connect jumper cables while the
key switch is on.
Can cause electrical voltage spikes
that can
damage electronic components.
Disconnect batteries prior to recharging (if
possible).
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.
Can damage electronic components.
Do NOT connect or disconnect electrical
connectors while the key switch is on or the
machine is running.
Can cause computer system errors from
interrupting a computer program while it is
running to damaged electronic components from
electrical voltage spikes.
Do NOT apply power or ground to any
component as a test unless specifically
instructed to do so.
Connecting the wrong voltage to the wrong point
of an electronic system can cause electronic
component failure.
When welding on the machine, make sure to
connect ground lead to the parts being
welded. For maximum protection,
disconnect all elec
tronic controllers before
welding.
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.
