hi, i have a 78 bulebird wanderlodge with a cat 3208.
it has just 4 6v batteries. these are used to start the bus and for the everything in back.

i bought 2 new deep cycle batteries to separate the coach (back lighting and accesories) form the engine starter.

but i dont understand how to isolate these. is there a main 12v fues panel? is it above the driver?

it tried to find one main wire that feeds that panel, but i can,t?

i thought i'd connect my deep cycles to that fuse panel, hmm.

please help.

There is a heavy red (#6) cable running behind the overheads on each side of the bus. This is the interior (coach) power. These cables join at the left front corner of the bus and run down to the battery compartment. Trace this cable run and find a logical place to separate it from the automotive system and connect it to the new batteries instead. Remember to provide a charge for the house batteries. A Schottky charge splitter or combiner relay can be used for this purpose.

Put a disconnect on the automotive batteries so they will be fresh when its time to start the Cat.

I suggest using the 4-6V batteries for the house and a group 31 or a pair of group 24 or 27 batteries to crank the Cat. This will provide more power for the coach and plenty for the Cat.
