I'm planning to put the battery in the aft location i.e. behind the rear seat, to minimize C of G problems. Main contactor is going in back with the battery, starter contactor in front near the starter. After concentrated reading of AeroElectric Connection, I thought I was going to run the battery negative forward to a forest of tabs located on the firewall - so I'd end up with two fat (2AWG) wires running forward, the battery negative to the single earth location, the big positive from the main contactor to the starter contactor, plus a 6AWG wire from the main contactor to the bus. So - do I need to earth the battery that way or could I earth it locally to the airframe?
As ever, thanks for advice.
