No power to axxera amv211nav

[edduval]

I recently upgraded to Lithium batteries in my 2020 A.C.E. Once completed, went to turn on the AXXERA unit and no response, looks like no power.

I checked the fuse in the converter power distribution panel, good.
Found another fuse behind the two house batteries, that is good too.

Can someone point out another location I should check???

I am hoping it is just a fuse

What else in the MH doesn't work?

Assuming it's JUST the radio, did you try the radio reset?
Have you checked for 12 VDC at the radio itself? Both main and keep-alive power?

Your dash radio also requires power from the chassis battery for the memory. Generally that fuse is a five amp in-line behind the radio.

When I swapped batteries, my Axxera died too. Mine was the "old fashioned" radio fuse in the factory chassis fuse box under the hood (class C). It shows the location in the Ford owner's manual.

The fuse behind the unit was okay in mine... it was a PIA to get to, but that's the first one I checked.

Everything else works. It took awhile to figure out how to pull the unit out Lol
I have 13 v on both the battery and the acc lines. I’ve tried reset, no luck.
Can’t find an inline fuse on the back 😂

Did you find the chassis radio fuse in the factory fuse box?
