Ken,
You said in the post to Steve:
"So each branch would need it's own fused service, or in other words a fuse
block, which you already have."
The problem as I see it is that there is NO fuse protection between the +
main battery terminal and the fuse block, or between the + main battery
terminal and the starter, or between the + main battery terminal and the +
auxiliary battery terminal (if you have one). These unfused wires carry
significant amps and they are routed under the van. Should the insulation on
these wires be damaged there is a real danger of them shorting to the frame,
and the potential for a fire. Seems like it would be nice to have them
fused. My 2 cents.
