Paul - the top comment was for you about leisure batteries. The second comment was about the original thread if any one can remember that. It was about getting 24v for a compressor. I said go with a 12v start and use the relay perhaps for a different purpose to get 24v supply.
Yes the passenger side battery is the maion battery. I found that a touch confusing to begin with. But with it now. You need to pick up the bits and bobs on the driver battery by running a flying lead from the starter battery over to the aux battery side where you disconnect the odd bits and re connect them to the new lead. Then you have a totally isolated aux battery.
Trust me I do know the difference between serial and parallax
I'm sure I think I do at least.
