I was basically asking for a double check on what loads are on S9 for
a 1981 Westy. The fuse seems pretty large for what appears to be a
relatively small load so I thought maybe I'd missed something. My fog
lamp relay switch (85, 86 circuit) and a wire for future loads are now
on that fuse. I didn't want to install that future load wire if S9 was
already maxed out with loads.

The Hella fog light kit c/w a fuse and holder and are connected to the
30 circuit but are wired so I can switch them on/off independent of
the headlights. But I hadn't thought to wire them so they aren't
potentially an extra load when cranking starter. The alternator to
starter post wire is larger than stock, and the wire from there to
starter battery is from an '85 Vanagon. I think 6.0 metric is larger
than AWG 8. But I think I would be wise to upsize that 6.0 wire.
