Heres what my vac system looks like as of 2 owners ago.
The
X's mark org lines that are gone.
The
red lines are the new connections.
The one port on the side of the switchover valve (81)
is open, no hose, no plug.
The EGR hose port on the vaccumm converter is hotglued shut.
The threeway enroute to the brake booster check valve... 140
is a fourway... that goes direct to the check valve (drawn in red)
Ill be checking the brushes on the regulator when the sun comes up.
Curious if there are other issues that could cause lack of charge,
as it started after replacing that fuse.
