Looking at converting the two cranking batteries in 2011 Navara to a dual battery system. Auto-sparky mentioned that the Navara currently has the earth connected to the side of the engine bay but with a dual battery system it needs to be connected to the block, any truth to this, how hard is it to do? Anyone done this conversion?

Hi Lach,

There is no reason to disturb or change the existing earth point. Just be sure that when converting the existing second cranking battery to an auxiliary battery in the dual system that the original main earth cable which provides for the starter return path is retained.

The negative of the new auxiliary battery should also be connected to the same stud on the side of the engine bay and not to the cranking battery negative post.
The main negative to your auxiliary loads should also be connected to this stud.

More information on auxiliary battery setups and wiring diagrams may be obtained from my blog here.
