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 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.
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 (not applicable to the 87122).
In this mode, full charge may never be reached to
allow the CHARGE COMPLETE light to turn on.
Switch to 10 amp, 12 amp, or 15 amp - 12 volt
setting (as applicable).
If green “Charge Complete” indicator does not
come on at least once in a day of charging, set the
SELECT SETTING switch to “Start” (“Activate” on
87122) and charge for 30 minutes. If the “Charge
Complete”indicator fails to come on during this
time, discontinue charging. Have the battery
professionally tested. If the battery is defective,
replace battery. If battery is OK, call Battery
Charger Service at (800) 328-2921.
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.

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.
If ammeter reads zero, the internal circuit breaker
may have tripped. Wait six to seven minutes. The
circuit breaker will reset automatically and the
ammeter needle will again register amperage.
Charge battery for another 5-15 minutes and
attempt to start the engine again.
If after several attempts, the engine still won’t start,
there may be a problem with the engine that will
need to be corrected before it can be started.
