General
The car has a voltage-regulated AC alternator.
The electrical system is single-pole and uses
the chassis and engine casing as a conductor.
The battery capacity is dependent upon the
equipment level in the vehicle. If the starter
battery is replaced, therefore, you must ensure
that you switch to a battery with the same
capacity as the original battery (see the label
on the battery).
