I know, I DID state that I had experience with this, didn't I???

Indicator is fed from fuse #5 and it was
never said the car was powered up or not.
Fuse #5 is hot with ignition on.

Read this agian and again... and again... and yet again...
And still don't understand what you mean.
How can electricity be a diode??? If you mean that no power can flow
between two points at the same voltage you're right, but remember
(read again) that it was specifically stated that #12 is out!
So no power there!!!

> But Patrick explicitly stated indicator was responding to lever light:

If you take a good look at the wiring diagram which I know you have one,
and you understand what you are looking at, you can clearly see that the
indicator CAN light through the interior lights. It's simply in series
with ALL the door-lights AND the light you flip on...

But because there's 6 lights in the doors in parralel AND a non-lit
bulb has WAY less resistance, especially with higher wattage bulbs,
only the low-power indicator lights and the rest does not.
But is you pull them ALL the indicator will not light
because the series is interrupted...

> Lever lights ARE isolated from indicator by a diode.

No they are not; the diode by the indicator and the diodes under
the dash are in series, so current can flow there. And because of
lack of #12 fuse the diodes do NOT block, but are open to current.

Just admit it IS possible; it happens...

And to make sure you understand:

The red line shows the path the current takes.
