Electrical system - Yellow Flashing LED for Battery Select Switch

Ryno

I have a 2022 nuCamp 320s Boondock and last night I placed a plug into
the Cigarette Lighter socket located at the back of the camper, which
immediately sparked and blew a fuse. This morning I opened the fuse
panel and noticed a red blinking light next to a 15-amp fuse, pulled
the fuse and noticed it was burnt out. I replaced the 15-amp fuse and
the red blinking light disappeared. Before the fuse was replaced, I
also noticed an orange blinking light that maps to the wiring
diagram's 'Battery Select Switch'. However, the orange blinking light
did NOT disappear when the 15-amp fuse was replaced, and I have never
noticed the orange blinking light before this event (therefore I think

it is related to the blowing of the 15-amp

fuse).

In addition, I noticed a continuous green LED illuminated at the
location of the USB / Cigarette Lighter receptacle. I have never
before noticed this light either and so I think it is due to the
blowing out of the 15-amp fuse.

Can anyone help me understand what the lights mean and how I can make them not light up?

Update:

I called the manufacture of the power center, CONTACT | WFCO Electronics (Google search for 'wf-8735/8740'), and spoke with John. He was very helpful and mentioned that the orange light is normal (has anyone else noticed this). It is a toggle to select either a lead acid or a LiFePO4 battery.

ha! I had that same orange light and I too called WFCO and got the same response! I knew it was a toggle because I have lithium batteries, but I was concerned because it was blinking.  I noticed when I'm on AC power the light is solid and if on battery it blinks...as they said was correct at WFCO.

The light is mentioned in all of the Lithium converter manuals.........

But, why oh why....does it have to be a flashing yellow light?  Just......incomprehensible.

Here is the manual for the 8735, but I'm not sure of the exact model of the converter mentioned.  The descriptions of all the lights for battery charging are on page 4 and 5.

Mine does the same thing and it’s WFCO 8955 LIS with a lithium battery. Not sure why it doesn’t light up when switched to lead acid. It’s a mystery!
