If I try to turn the lights on and off they still don't work until I turn the truck of and on they come back on

Will sound like your Volvo is hitting the battery limitations. Once it gets to 11.9 volts the battery protection system kicks in, so you can start to try the next day
sounds like you have some week battery's or all the posts on the battery terminals need to be clean and also on the one on the starter and ground on the frame. -
Battery is at 13.9
-
check for loose connections at the batteries..also look for corrosion...also make sure the panel in your bunk is off..your bunk heater may be running & you dont know it

Dashboard led
Electrical fault active
Mid 216 psid 20 fmi 6 so i have this fault -
13.9 for the batteries seems a little bit high(I could be wrong though). If the truck is running and you check the gauge on the dash it will give you the reading of what the alternator is putting out. To get the correct reading on the batteries turn the engine off then check them.

Yeah volt are correct 13.9 its normal
-
So 13.9 volt when the engine is running?
-
Yea engine running 13.9 its normal for my truck.
