SC-7500A Error Codes
ERROR CODE DESCRIPTION REASON/SOLUTION
F01 The battery voltage is still under 10V
(for a 12V battery) or
5V (for a 6V battery) after 2 hours of charging.
The battery could be bad. Have it checked or replaced.
F02 The charger cannot desulfate the battery. The battery could not be desulfated; have it checked or replaced.
F03 The battery was unable to reach the “full charge” voltage. May be caused by trying to charge a large battery or bank of batteries on too low of a current setting. Try again with a higher current setting or have the battery checked or replaced.
F04 The connections to the battery are reversed. The battery is connected backwards. Unplug the charger and reverse the connections to the battery.
F05 The charger was unable to keep the battery fully charged in maintain mode. The battery won’t hold a charge. May be caused by a drain on the battery or the battery could be bad. Make sure there are no loads on the battery. If there are remove them. If there are none, have the battery checked or replaced.
F06 The charger detected that the battery may be getting too hot (thermal runaway). The charger automatically shuts the current off if it detects the battery may be getting too hot. Have the battery checked or replaced.
SC-7500A Troubleshooting
PROBLEM POSSIBLE CAUSE SOLUTION
The battery is connected and the charger is on, but isn't charging. The charger is in tester mode, not charger mode. Press the CHARGE START button to activate charging and select a charge rate.
Indicator lights are lit in an erratic manner not explained in the “Using Your Battery Charger” section. You might have accidentally activated a special diagnostic mode. Make sure nothing is touching the control panel, then unplug the charger and plug it in again.
DIGITAL DISPLAY always flashes before the battery is completely charged. The incorrect battery type may have been selected. This will happen if the battery did not reach full charge within 24 hours. May be due to a very large battery or a bank of batteries requiring more power than the charger can deliver within 24 hours. The battery may also be faulty. Reset the charger by briefly unplugging it or briefly disconnecting the negative battery clamp. Select the desired rate (SMALL or LARGE BATTERY) and BATTERY TYPE again, if necessary.
The green CHARGED LED lights a few minutes after connecting to the battery. The battery may be fully charged or recently charged, leaving the battery voltage high enough to appear to be fully charged. If the battery is in a vehicle, turn the headlights on for a few minutes, to reduce the battery voltage; then try charging again.
The incorrect battery type may have been selected. Reset the charger, by briefly unplugging it or briefly disconnecting the negative battery clamp. Select the desired rate (SMALL or LARGE BATTERY) and battery type again, if necessary.
The charger is making an audible clicking sound. Circuit breaker is cycling. The settings may be wrong. Check the charger settings.
The battery is defective. Have the battery checked.
Shorted battery cables or clamps. Circuit breaker cycles when current draw is too high. Check for shorted cables or clamps and replace, if necessary.
Severely discharged, but otherwise good battery. The battery may not want to accept a charge, due to a run-down state. Allow charging to continue until battery has a chance to recover sufficiently to take a charge. If more than 20 minutes, stop charging and have the battery checked.
Reversed connections to the battery. Shut the charger off and correct the lead connections.
Charger makes a loud buzz or hum. Transformer laminations vibrate (buzz). No problem, this is a normal condition.
Shorted Diode Assembly or Output Rectifier Assembly (hum). Have charger checked by a qualified technician.
