Loren:
Great discovery there.
And yet these changes and additions (jiggery-pokery) are a
two edged sword. I revel in and admire the detail some of us put into
our Westies but am reminded of what my SO says about these details.
The next person to get the van will have a real headache trying to
fathom all the wiring and plumbing. To say nothing of oneself getting
confused if you haven't made copious notes over the years.
I discovered a relay mechanism I had installed a few years
prior to an episode requiring repair in an old MGB I used to own. I
swore at the complexity of the gibberish I was unravelling only to
discover that it wasn't the source of the problem and had functioned
perfectly well over the years. But! damned if I could figure out why
I did it.
'Old Age' I guess.
Still in all, keep up the 'Rube Goldberg' extras as I really want to
inspect your Van one day, it sounds like a marvel of ingenuity.
Regards!
