This will shorten the wire run I need to do for the ACR wire.
Also, does it look like I have the fuses in the correct location?
The major issue you have is that your start (reserve) bank and your house bank are incorrectly tied together on the positive side. They are NOT separated, regardless of your ACR location. The acr should be between the two positives of your house and reserve bank, not where it is shown.
You seem to have a complete misunderstanding of bus bars.
It appears you are using a simple 1-2-B switch, in which case you may be interested in reading this, starting with reply #11: Alternator/Batteries & "The Basic" 1-2-B Switch BEST Wiring Diagrams
House bank to post 1, reserve bank to post 2, output of the switch from the C post is to the DC distribution panel and to the starter, alternator output to the house bank with a circuit breaker rather than a simple fuse, ACR between the reserve and house bank for charging.
You also seem to have connected the DC ground from the house bank to the AC ground through the Blue Seas vsm 422.
I also agree with Maine Sail, see this thread, the issues are down the bottom of the first page and the second page: 310 Battery Info - SailboatOwners.com
The Blue Seas dual circuit switch is a disaster waiting to happen and is a stupid design. Stay with the 1-2-B switch, but please learn how it is supposed to work.
A recent post on this board has some other good reference material. The Best Way To Learn Electrical
Ample Power has already designed the wiring diagrams you NEED. Please read their stuff.
I certainly wouldn't wire my boat this way. Because it simply will not work. Review the linked reference and make some corrections. It won't work as shown. You asked.
