Looking for advice. I purchased from new a 2011 Autotrail (Excel670B). The leisure battery has 3 cables going to it's negative terminal. One brown and two black, one of these slightly thicker than the other.
Would I be right in thinking the thickest black is the ground cable to the vehicle chassis, the other black being the link to the second leisure battery to wire them in parallel and the brown one from other services
(Is it possible to confirm this with a multi meter and if so how !)
(As a matter of interest I'm looking to transfer all negative connections less the ground on this battery to a 'shunt' as I will be installing a battery monitor)
Thanks in advance.
