Thanks Mark, looks like there's plenty of slack to move things around. Switch works so far, gonna need some bigger terminals to fit the 1/0 starter cables then the switch can shut everything off.Greg @Pighead make sure you make the ‘out’ wire long enough to reach the ‘in’ terminal for the eventuality of a voltage drop inside the switch. I’ve removed a couple of ‘marine-grade’ dual battery/ cutoff type switches from customer’s rigs over the years, usually after they’ve wasted money on a new starter because they couldn’t believe that anything marine grade could degrade.
