I have a 2006 Volvo VNL and on the ac control panel in the sleeper there's a blinking red light when the truck is not running. Not sure if it's doing it while the truck's running havn't checked that yet. I just got this truck not too long ago and havn't used it to pull anything yet still working on it to get it in trustworthy condition if that's even possible lol so there wasn't any power going to the panel when I got it found out that the fuse had been pulled so put the fuse back in and lights on panel came back on and then shortly after the blinking red light.. I've been having electrical issues with this truck so there's that.. Anyways if any of you have any idea's on what it is I'd appreciate your input. Thanks.

That light is for the low voltage warning.. should also be a beeping. And the switch (for the rear fan) on the dash should also be blinking.
1st check and make sure the batteries are fully charged. If they are you may have a bad low voltage disconnect..baha Thanks this. -
I cleaned up my ground cables off frame and batteries and that solved the issues I was having with the low voltage disconnect.
Also my apu terminals were part of the problem. -
Fantastic.. I have the battery charger hooked up at this time so there should be constant voltage going so but I'm not sure one of the battery's isn't bad.. I bought 4 new batteries not too long ago but they'be been drained down to nothing a couple of times, but I've charged them back up although there's at least one or 2 that went bad through that..
x1Heavy Thanks this. -

Also how's the starter sound, do your internal lights dim when you turn perephrial systems like headlights/wipers on? Dash flicker? -

I hope you are not using the very large machined pegs made of steel provided by the factory for connecting electrical power to the truck that sits behind one of the sleeper fairings and is covered by a black and red type rubber bushings when not in use.
