TROUBLESHOOTING
Fault LED Lit
The following conditions may light the FAULT LED:
• Poor connection to battery (or frame).
• Charging too fast – decrease charge rate by pressing the Charge Rate Selec-
tor 2A/4A/6A button to select a lower rate.
• Charging too slowly – battery is large and did not complete charging in 24
hours. Press the Charge Rate Selector 2A/4A/6A button to select a faster
rate.
• Shorted battery cell – check battery.
• Open battery cell – check battery.
• Internal shorted battery cell – take your battery to a certified automotive ser-
vice center for evaluation.
• Internal overheat in charger – make sure fan is not blocked.
Try charging another battery, if the FAULT LED does not light, then one of the
above problems exists with the initial battery. Charger will not charge and the
fan will not operate if there is a fault. Call Customer Service toll free at (800)
866-2161.
Reverse Polarity LED Lit
• Incorrect polarity – follow the steps outlined in “Important Safety Instructions”
at the front of this manual.
Battery Not Accepting a Charge
• Make sure that the charger is plugged into a “live” 110/120 volt AC outlet and
Power LED is lit.
• Unplug the charger and check battery connections – ensure that there is a
good connection at the battery terminal and/or vehicle chassis.
• Check that the correct charge rate was selected for the battery being
charged.
• Ensure enough charging time was allowed to charge battery.
Charging a Very Cold Battery
If the battery to be charged is extremely cold (in temperatures below freezing
– 0˚C/32˚F), it cannot accept a high rate of charge, so the initial charge rate will
be slow. The rate of charge will increase as the battery warms. NEVER attempt to
charge a frozen battery.
