d:: (Turn OFF all vehicle’s accessories): The battery must be fully charged before testing the alternator. Run the engine
long enough to achieve normal idle speed and verify there is a no-load voltage.
1. Press Alternator Check to start the check.
2. Alternator Good LED will light to indicate the alternator is good, or the FAULT LED will light to indicate the alternator
may need service.

d:: (Accessories ON): Next, load the alternator by turning on as many accessories as possible (except for A/C
and DEFROST)
1. Press Alternator Check to start the check.
2. Alternator Good LED will light to indicate the alternator is good, or the FAULT LED will light to
indicate the alternator may need service.
3. Press Alternator Check again to stop the test.
If the first alternator check indicates a good alternator and the second indicates the alternator may need service, the
problem could stem from: loose fan belts, an intermittent diode failure or possibly bad connections between the battery
and alternator and/or ground.
N
Nootteess:: BATTERY VOLTAGE button is disabled in Alternator Check mode.
The FAULT LED may light because someone has added a number of accessory loads on the charging system, thereby
increasing current demand from the alternator. MAKE SURE THAT THE ALTERNATOR IS RATED TO SUPPORT THE
APPLICATION.
This check may not be accurate for every make, manufacturer and model of vehicle. Check only 12 volt systems.

and stop when the battery is fully charged. Deep cycle batteries may require longer charging time.
For estimates of the time it takes to charge a battery, refer to the following table.

*NR = Not recommended at 2 amps — use a higher charge rate.
The times shown in the table above are approximate and refer to a 50 Ah automotive battery. For example, a 50 Ah (12
volt) battery is discharged (50%). How long should it be charged at the 10 amp rate? See the chart above under “50%”
and “at 10 amp rate.”
In most cases, battery charging times will vary depending on the size, age and condition of the battery. Smaller batteries
should be charged at a lower rate (2 amps) and an extra hour added to charge time.

When F02 appears, the most common cause is poor connection to battery.
• Follow the steps outlined in “Important Safety Instructions” at the front of this manual to disconnect AC cord and
clamps, clean battery terminal and reconnect.
• If the situation persists, we recommend taking your battery to a certified automotive service center for evaluation.
