Attempting to work on electronic components
without proper equipment can damage internal
parts with static electricity.
Do not work on the electric system without
proper tools and training. Repair work on the
electrical system must be done by trained
professionals. Your authorized Autocar
service facility has the right tools and trained
technicians.
Charging System
An alternator with an integrated voltage
regulator is used to supply power to the vehicle
electrical system. The charging system voltage
should be checked periodically to prevent
overcharging or undercharging the batteries,
and to detect any voltage drop in the wiring.

DANGER
When inspecting or cleaning batteries,
never smoke or expose batteries (or
the area around them) to sparks or
flames. The battery area may contain an
explosive gas mixture that can ignite,
causing an explosion, leading to serious
personal injury.
There may be two to four batteries installed.
Always make sure the batteries are fastened
properly in the battery box (Figure 130).

Safety Guidelines
WARNING
Failure to repair a malfunction in the
electrical system can result in serious
damage due to vehicle fire. Always let an
experienced electrical technician perform
repairs. Always determine the source of
the fault; do not just treat the symptoms.
WARNING
Always wear eye protection when
working around batteries to prevent
the risk of injury due to an explosion or
contact with sulfuric acid.
NOTICE
Electronic circuits and components are
designed to sense voltage differences
less than one volt. While static electricity
is not normally dangerous to humans, it
can seriously damage electronic circuits
and components. Circuit boards mounted
in the instrument cluster, for example,
may not fail immediately after being hit
with a static discharge. Rather, they
may work for a while and then fail for
no apparent reason. (Always work with
proper grounding straps and antistatic
mats around electric components.)
Today’s vehicles contain many electronic
devices. It is very important to exercise caution
when working on a modern electrical system,
charging batteries or jump-starting the engine.
To minimize the risk for any damage to the
electronic components, follow the procedures
below when work is being done to the electrical
system.
