ENGINE ELECTRIC SYSTEM
Vehicle accessories are left on overnight.
Slow average driving speeds are used for short periods.
The vehicle’s electrical load is more than the alternator output, particularly with the
addition of aftermarket equipment.
Defects in the charging system, such as electrical shorts, a slipping alternator belt, a faulty
alternator, or a faulty voltage regulator.
Battery abuse, including failure to keep the battery cable terminals clean and tight or a
loose battery holddown clamp.
Mechanical problems in the electrical system, such as shorted or pinched wires. -

3) CHARGING SYSTEM
Alternators use a new type of regulator that incorpo-rates a diode trio. A Delta stator, a rectifier
bridge, and a rotor with slip rings and brushes are electrically similar to earlier alternators.
A
conventional pulley and fan are used.
There is no test hole.
4) CHARGING TIME REQUIRED
The time required to charge a battery will vary depending upon the following factors:
Size of Battery
- A Completely discharged large heavy-duty battery required more than twice the recharging
time as a completely discharged small passenger car battery.
Temperature

8c009900a000470088009b004700540058005f00b6006a0047>(0°F) than at 27°C
(80°F).
When a fast charger is connected to a cold battery, the current accepted by the battery will
be very low at first. The battery will accept a higher current rate as the battery warms.
Charger Capacity
- A charger which can supply only 5 amperes will require a much longer charging period
than a charger that can supply 30 amperes or more.
State-of-Charge
- A completely discharged battery requires more than twice as much charge as a onehalf
charged battery. Because the electrolyte is nearly pure water and a poor conductor in a
completely discharged battery, the current accepted by the battery is very low at first. Later,
as the charging current causes the electrolyte acid content to
increase, the charging current will likewise increase. ▶
