6. If the engine does not start after a second or third attempt, disconnect the charger and
replace the battery.
NOTE: Before replacing the battery, use a battery analyzer to test it. If the battery is
discharged and still useful, determine if the starting and charging systems are normal.
CAUTION: Do not start a vehicle if the battery is not installed properly. Damage might occur to
the electrical system.
CHARGING MULTIPLE BATTERIES
PARALLEL CHARGING
You can charge batteries of the same type and voltage rating by connecting them in parallel.
Charging two batteries in parallel takes twice as long. Charge time increases with the number
of batteries. Rate of charge decreases with the number of batteries. Each battery receives 1/2
the amount of charge on the ammeter. For example, if the ammeter shows 40 A, each battery is
receiving a 20 A charge.
SERIES CHARGING
You can charge batteries of the same type and voltage by connecting them in a series. The
RATE/VOLTAGE CONTROL switch is the sum of the voltages and current through the
batteries. This number is the amount of charge on the ammeter.
For example, charging two 12 V batteries in a series requires a 24 V setting on the RATE/
VOLTAGE CONTROL switch. If the ammeter shows 30 A, each battery is receiving a 30 A
charge.
