1. NO AMMETER READING and NO

INDICATOR LIGHTS (Charging
has not yet started)

•  Make sure charger is plugged into

a LIVE AC outlet.

•  After unplugging unit, check

connections at battery. Make sure
the battery posts are clean and
the clamps are making good
contact with the battery terminal
and other point of connection. 

•  Check to see that battery is

capable of being charged. It may
be damaged, sulfated, or have an
open circuit.

•  Make sure you have selected the

proper charge voltage for the
battery being charged.

•  Battery may need preactivation

(see the paragraph entitled
"Preactivation of a Discharged
Battery" in the OPERATING
INSTRUCTIONS section).

•  Verify that the vehicle’s battery

cables are in good condition and
properly connected to the battery,
especially the ground terminal.

•  The battery may already be 

fully charged.

2. LOW AMMETER READING and

NO INDICATOR LIGHTS (Charging
has been in process)

•  Battery is nearing full charge,

green light will eventually turn on.

•  The 2 amp setting has been

selected for charging a larger 12
volt battery. Full charge may
never be reached to allow the
CHARGE COMPLETE light to
turn on. Switch to 12 volt, 
15 amp setting.

•  If green CHARGE COMPLETE

indicator does not come on within
8 hours of charging on the 12
volt, 15 amp setting, have the

battery professionally tested. If
the battery is defective, replace
battery. If battery is OK, call
Griot's Garage at (800)345-5789.

•  If meter reading is between 1 and

5 amps on the 15 amp setting,
have the battery professionally
tested or replaced.

3. NO AMMETER READING,

REVERSE HOOK-UP INDICATOR
IS ON

•  The charger’s output cables are

reversed at the battery and other
point of connection. Unplug
charger, correct the hook-up, 
then plug charger in and 
resume charging.

4. NO AMMETER READING, BUT

CHARGE COMPLETE INDICATOR
IS LIT

•  Battery is fully charged. Charger

may be disconnected at any time.

5. CHARGE COMPLETE INDICATOR

IS ON, BUT BATTERY EYE DOES
NOT INDICATE FULL CHARGE

•  When the CHARGE COMPLETE

indicator comes on, the battery IS
fully charged. However, due to
electrolyte stratification, the
hydrometer eye in the battery
may not immediately indicate full
charge. To get the eye to register
full charge, set the SELECT
FUNCTION switch to START and
charge for one more hour on the
15 amp setting.

6. VEHICLE WILL NOT START 

WHEN USING THE ENGINE
START SETTING

•  After unplugging unit, check

connections. Make sure the
clamps are making good contact
with the battery terminal and
other point of connection.
