CHECKING THE CHARGED BATTERY
To check the battery you charged:
1. Turn the TIMER to OFF.
2. Unplug the charger.
3. Disconnect the charger clamps.
4. Start the vehicle.
5. If the vehicle does not start after a few attempts, do the steps under "Performing an engine
start" or 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.
PERFORMING AN ENGINE START
The engine start powers a vehicle with a discharged battery. You can use this feature when the
battery in a vehicle does not have enough capacity to start the engine.
To do an engine start:
1. Turn the RATE/VOLTAGE CONTROL switch on the charger to a fast charge setting
(30–70 A).
2. Charge the battery for five minutes.
3. Select ENGINE START and set the TIMER switch to HOLD.
4. Start the engine with the ignition key.
When the engine starts, the alternator in the vehicle charges the battery as long as the
engine runs so the engine starts by itself the next time.
NOTE: The engine might not start on its own the next time you start the vehicle, even if
it starts and runs from this procedure. If it does not, you might have a bad battery.
5. If the engine does not start in three to five seconds:
a) Stop cranking.
b) Turn the RATE/VOLTAGE CONTROL switch to the fast charge setting (30–70 A).
c) Charge battery for five minutes.
