Re: Typical isolating diode location?
I agree with your take that the charging cable doesn't need to go thru the isolation switch. In my experience not going thru a switch is the norm. I think you should go ahead with your plan to install a VSRs nonetheless. Although most alternator outputs are not fused, the ABYC standard I recall is to fuse anything within a certain distance of the battery terminal. You never know when you may short out that connection.
