If you move the ML ACR to the loads side of each battery switch it will provide the ability to isolate a bad bank and use the other bank to do house and engine starting in manual parallel mode. With it on the battery side you would need to remove a lug or fuse in order to isolate a bad bank while at the same time allowing the other bank to do everything.

The ML ACR can be used for this but is less than ideal because if you want charging capabilities from say solar, when you are not there, then you'd want it where you put it. In a bank failure, where it is now, provides less flexibility and isolating ability of banks....

I generally prefer a simple on/off emergency switch on the loads side of start & house then an ACR or Echo on the batt side....

Thanks Maine Sail. So pretty much back to how I had it before I'll draw up a new diagram tomorrow to get back on track.

ok, here we go with standard ACR & emergency switch. Maine Sail, do you have any recommendations for service switches, say on the alternator line?

normal battery switches or something else? obviously voltage drop is the big concern with the charge feeds.

Or would you normally pull the ANL fuse if fitted? thanks
