Flashing light in fuse box

I have a 2015 Montana fifth wheel. Happen to replace the battery today and noticed the green light in the fuse box was flashing. Tried to find the answer on line and was not successful.

Camping world was working on my camper and they had it long enough for the battery to totally discharge. They had to jump it off so I could hook it up. The service person hooked it up backwards and the camper started lowering. After we spoke loudly he responded and disconnected the battery. So battery would not charge, it was under warranty so got a new one and installed it today.

Is the flashing green light normal, or is it telling me something.

THANKS YALL LOOK FORWARD TO YOUR WISDOM!

    From what someone posted it may be normal. And that blink pattern for a green light... Sounds like the Progresive Dynamics Charge Wizard indicator light.. If you you have one of the top of the line converters. Don't get better than the Charge Wizard.. couple as good.. none better.

    I'd recommend having a certified RV technician inspect the electrical system and track down the cause. Flashing lights on the fuse panel generally mean something is not right. Once identified, the issue can then be properly repaired.

    See if this answers your question: Montana

    From Forest River:
    Light “ON” all of the time – Indicates the unit is in the BOOST MODE and the converter output voltage is 14.4-volts and is in the process of recharging the battery up to 90% of full charge as fast as possible. This mode is usually automatically selected after dry camping

    Light Blinks Rapidly (from once to many times a second) – Indicates the unit is in the NORMAL MODE and the converter output voltage is 13.6-volts. In this mode, the converter is safely completing the charge of the RV battery.

    Light Blinks Slowly (every 6-8 seconds) – Indicates the unit is in the Storage Mode and the converter output voltage has been lowered to 13.2-volts. In this mode the RV battery is fully charged and the converter is maintaining the charge, without causing gassing or water loss.

    Your question is pretty generic. But if you have future Montana specific questions go over and try the Montana Owners Club (MOC) forum.

    If 'Tech' hooked battery up backwards then Reverse Polarity Fuses on Converter BLEW

    Which means DC Fuses are NOT being powered by converter OR battery

    Reverse Polarity Fuses....should be 2 and could be 30A or 40A

    Post Brand/Model of AC Panel and converter
