Troubleshooting - Vector VEC1090 A Owner's Manual & Warranty Information

TROUBLESHOOTING - FAULT LED LIT
NOTE:
Charger will NOT operate on batteries below 4.0 Volts. If a 12 Volt battery is below 4.0 volts it is probably
shorted, open or sulfated and should be replaced.
The following conditions may light the FAULT LED:
• Poor connection to battery (or frame).
• Charging too fast - Decrease Charge Rate - Press 2/10/20A button to lower rate.
• Charging too slowly - Battery is large and did not complete charging in 24 hours - Press 2/10/20A to charge at a faster rate.
• Shorted battery cell - Replace battery (F01).
• Open battery Cell - Replace battery (F03).
• Battery sulfated - have battery serviced or replace battery (F03).
• Reverse Polarity LED Lit - disconnect AC then reverse clamp locations on battery and frame.
• Internal over-heat in charger- make sure fan is not blocked (F05).
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 Vector Technical Support toll free: (866) 584-
5504.
SULFATED BATTERY (F03)
Batteries left in a discharged state for a long period of time are likely to become "sulfated". Sulfated batteries cannot
accept a high rate of charge since the internal plates are coated with lead sulfate. To determine if a sulfated battery can
be "saved", follow the instructions in Battery Recondition.
INTERNAL SHORT CELL BATTERY (F01)
• If the battery being charged has an internal shorted cell, the FAULT LED will light.
• If FAULT LED light comes on, Vector recommends you take your battery to a certified automotive service center
for evaluation.
BATTERY NOT ACCEPTING A CHARGE
• Make sure that the charger is plugged into a "live" 110/120VAC outlet and Power LED is lit.
• Unplug charger and check battery connections - ensure that there is a good connection at the battery terminal and/or
vehicle chassis.
• Check the battery for sulfated condition.
• Check that the correct charge rate was selected for the battery being charged.
• Ensure that enough charging time was allowed for-check table in Appendix A (page 11) for approximate
charging times.
VERY COLD BATTERY
If the battery to be charged is extremely cold (in temperatures less than freezing - 0º C/32º 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.
WARNING: DO NOT attempt to charge a frozen battery.
