Sounds about right. Might just be one battery that is dead sucking power from the others.

With no error code it sound like there might be a bad fuse. If the truck were to close the contactor it would throw a code. Sometimes a fuse can blow up still allow low current to pass thru. Try removing that fusecand testing the resistance. Otherwise the tips on the contactor might be burnt.
