Interesting. Since Dan's schematic (which I've attached in case you don't
already have it) doesn't show a brown/red at all, I wonder if perhaps you have
the wrong switch.

That's definitely a problem then. The light would only go out if the switch is
no longer supplying power into the 'white' ignition circuit, which means the
engine wouldn't start even if it was cranked.
If other things (like the horns) quit working when you hold the switch in the
start position, then I'd say you've got a bad connection somewhere between the
switch and the battery (or possibly on the ground side of the battery).
Otherwise, it's most likely a bad (or incorrect) switch. To be sure, check for
voltage at the switch terminals, while trying to crank the engine.
