Arctic Fox 1150 onboard batteries

I have a 2019 AF1150 and don't see any charging of the house batteries while driving, is this OEM or do I need to check for fuse/other issues?

I didn't notice the lack of charging until we recently started boondocking and moving every other day. Our battery bank was always at 100% given we have 340W solar and (3) 100 AH Lithium batteries and didn't use much power. But, I love our new Starlink, the wife likes the espresso and heater in the cooler months, so the inverter that runs all of that 24/7 is now drawing enough power and identified the problem during relocation trips.

Appreciate any help. Its not a huge deal as the solar normally brings all back up, but it would be nice if the rig would charge while driving.
  • Thanks to all.... Power from the truck was the issue, the bed connector was the culprit. However, taking SoonDockin's and others great advise and ordered all the components to install a dc/dc charger.
  • I 3rd the dc to DC option.

    I did replace the charging fuse in my class C with an automatic circuit breaker.
  • ^^^^^^ Yes Victron make a nice DC/DC charger. I have a 30 amp one and it will keep my batteries topped off and refil if we use the AC or microwave during the day. We have a 12v fridge and it easily keeps the batteries topped off with that. I then disconnected the 12v line in the 7 pin connector.

    First, verify that you ARE getting power from the truck.

    Second, you really need a DC-DC charger. It creates the proper voltages to charge your lithium battery (different voltages than lead acid).
  • Most likely you blew a fuse on your truck, check the 7 pin connector for 12 volt power.
  • The first check I would make is a voltage check at the batteries with both the solar and the truck disconnected.
    (Hopefully, you have an on/off switch to the solar panels.)
    Then start the truck and wait for about a minute before checking the battery voltage again. The voltmeter should now be reading a higher voltage charge from the truck.
    Are you getting a charge from the truck?
