No isolation switch shown here other than your normal start/run switch and I'm assuming this is set up correctly. So is the isolation switch required for the ACR to work or is it installed for a different reason? Just curious because on my boat I have an isolation switch that's tied to the house battery only and is positioned no where near the ACR. I switch it off to power off everything connected to the house battery whenever I shut the engine down. I can start the engine without turning this isolation switch on so I assumed that it had nothing to do with the ACR. And yes I know what butt-U-Me means. I'm just very electrically challenged and very willing to learn.
Again, my electrical knowledge is very limited but I would think that the answer is no. When you are not operating, anything that you have left on will draw down the battery. Having an ACR would not change that.
