Read the instructions, I know who reads them, but the Blinking Green lite give you the different modes that the Converter goes through.
Here's a snip from the Manual:
BOOST MODE – Indicated by green LED remaining on. The output voltage is 14.4VDC to rapidly recharge the battery up to 90% of full charge.
NORMAL MODE – When the battery is between 50% and 90% charged, the green LED will flash once per second. When the battery has reached
90% of full charge the green LED will flash 2 - 3 times per second. In this mode the output voltage is 13.6VDC and the converter is safely completing
the charge of the battery.
STORAGE MODE – Indicated by green LED flashing every 6 - 8 seconds. In this mode the output voltage has been lowered to 13.2VDC, the RV
battery is fully charged and the converter is maintaining the charge.
MANUAL BUTTON - The manual button has been provided to allow the operator to temporarily override the converter (not recommended) or to
verify the converter is operating properly. For manual operation, Press and Hold the button. The indicator light will soon remain “ON” indicating Boost
Mode. Continue to hold the button and the light will blink rapidly indicating the converter is in the Normal Mode. Continue to hold the button until the
light blinks slowly indicating the converter is now in the Storage Mode. After the manual button is released the converter will stay in the selected
mode. When the battery charge status changes, the converter will return to the automatic mode of operation to prevent damage to the battery
