Side-stand kill switch

I REALLY don't like the idea of safety disconnects failing & leaving
you stuck on the side of the road. Early on I closed the circuit for
the clutch disconnect when that switch failed. The side-stand
disconnect; I had a problem with the plug on the wire-harness side
which inspired me to undertake another project; sounding the horn
rather then killing the engine. I tied the wires together that were on
the side stand-switch plug. Again, more later on all that wire going
through the bike. Anyway, the way I figure, if any part of the new
side-stand alarm failed, at least the bike does not stop running.

You can't just run power through the side stand switch since the
circuit is closed when the side-stand is up. I used a relay and
connected power to it and the side-stand switch was the ground
supplied. Power sent from the relay to a flasher ?relay? to the horn
relay. When the side stand switch circuit is open, the horn cycles on
& off. I wanted to get a bit fancy & have the neutral indicator close
the circuit & keep the horn quite, but quit a bit of smoke came out of
my head for this one. I did learn a lot!

I easily rigged up another relay to do what I wanted, but there was a
problem; the neutral indicator light on the dash would stay on with
the side-stand up & the bike in gear. The ground from the
side-stand switch feed back & grounded the neutral indicator light. I
now FINALLY understand relays, why there are so many used & how cool
they are! The second and third are OEM BMW relays. The third relay had
power into it, the ground to close the circuit came off the second
relay. Activating the third relay closed the circuit that operated the
neutral indicator light. Since a relay is two totally separate
circuits, everything works great!

The horn gets you attention if you forget to put up the side-stand
while also in gear, even with insert ear buds & music at full blast! I
ended up using a fancy after-market relay that had two circuits &
allowed you to do two separate functions for the first relay (The
other two are the OEM BMW black relay). I'm also thinking of hooking
up a ?safe? light which would work off the second half of the first
relay as extra precaution. Trying to find something that illuminates
and then goes out after a minute or two until the circuit is opened &
closed again. Any suggestions? Looks like more complicated wires &
gizmos, but none of them keep the bike from going down the road.

One last thought... what happened to an old fashion spring picking up
the stand when the bike is uprighted? Hmmmm.
