Subject: | Re: Stall Warner - switch problems |
Hi Clive,
My stall warner switch has worked reliably for about 15 years, so my memory of
an initial problem is vague. But your "it is closed/the horn sounds once the a/c
is back on the ground/at zero to low forward speed" rings a bell in my head.
I'm my case it was caused, as far as I can remember, by the air pressure tube/s
being fitted to the wrong spigot/s. Simply swapping the tube/s around cured it.
The adjustment screw in the middle needed little or no turning to get the warner
to activate at 5 knots above stall.

I fixed it by fitting a Smartass, easily heard via headset & impossible
to ignore, neither of which can be said for stall warner even when
working - which sounds as a very distant minor squeak using modern
headsets!

please? The pipe between switch and the hole just below the wing leading edge
is correctly connected to the NO port A btw.
