I still have a problem charging my aux. battery. The 3 post
solenoid is OK. The small wire that goes to the center post does
not get 12v when the engine is running. I have traced it through
the firewall to a black wire with a blue stripe on a 12 pin
connector on the back of the fuse panel. The wire does not ever get
12 volts.
1. What am I missing?
You're very, very close. You have two choices: Figure out why 12V
isn't reaching that wire, or connect the solenoid to another switched
12V connection. To do the first, it would be easiest if you had a
wiring diagram for your year's EV. I'd start looking in the Bently
manual. But it sounds like you're thinking about the second option.
2. Can the wire to the solenoid center post go to any switched 12v
connection?
I don't see why not. It will draw very little current. Of course, it
must be a switched circuit that is not energized when the engine is
off. For safety's sake, the solenoid should take its power from
something DOWNSTREAM of a fuse, so that the fuse will protect you if
there's ever a short circuit in the solenoid.
Which brings up the point -- it wouldn't hurt to check your fuses for
continuity, on the off chance that a blown fuse is causing your
trouble. Offhand, I'm not sure which circuit that solenoid is powered
from, though.
