Ammeter to Voltmeter...who does it?

Mattax said
The problem with MAD's design is all the power to run the vehicle must go through several more splices and two fusible links.
Even in a situation where recharging a very low battery is frequently needed, this is not a good design.
If say, with a situation like your motor home, high current charging is frequently needed. Then a charging wire with fusible link can be added, but leave the alternator feed to the main junction as is.

I agree with your schematic to a point. However once you run the alternators output directly to the battery bypassing the bulkhead connector entirely, as long as the spades are clean and tight, you shouldent have to bypass the feed going back through them to the rest of the car because the load on the connectors shouldent be that high anymore, and the amp load is now split between 2 feeds going in through the bulkhead. I modified the schematic showing 2 voltage feeds through the bulkhead this splits the load going in.

Now on a motorhome, and its systems loading the wiring, he may want to use your schematic and bypass the bulkhead altogether. However in a passenger car, its not necessary.

See my modification of the schematic below.
