2) If the Control Board is working, check the Control Board for Fault Codes and verify proper LEDs are on.
The charger will show fault codes that can be used to help diagnose problems with the battery charging
system. See SECTION 15.1 for help solving Fault Code problems or improper LED function before
continuing.
3) If there are no fault codes, the AC and DC circuit breakers are on, and the charger is not functioning
properly; a complete power reboot may be required. This should only be done once and if the charger
does not return to normal operation, continue to the next step.
To do a complete power reboot, remove AC power by shutting off the charger AC breaker or AC power at the
source. Disconnect the battery voltage from the charger. With the charger DC breaker closed, let the
capacitor(s) in the charger discharge. The charger has a bleed resistor on the output, but to discharge the
capacitors faster an additional resistor may be used. Verify capacitors are discharged with a voltmeter. The
charger display and LEDs should all go off. Reapply Battery DC voltage. Using the charger control board,
verify charger settings are correct. Reapply AC power to the charger. This will return the charger to normal
operation, if there is no other internal component failure.
