Battery DEAD.......converter in overload mode (shut down due to high amp draw for dead batteries)
Check that 120V AC power is available to converter (circuit breaker or outlet)
Turn of CB or unplug
Disconnect battery POS cable at battery (tape off so it doesn't make contact)
Then turn on AC power to converter....DC output S/B 13.2V minimum or converter is bad
SHOULD provide DC power for all of dc system........replace battery (dead/discharged probably will not recover....can try to charge using a portable charger)
