Hi Steve

Very glad to hear you and aircraft got back on the ground safely.  Yes, 
events like those really do use up seat cushions - don't they.  Glad you 
found the problem - amazing how little things like adding tie wraps can 
cause such an exciting "adventure".

I too have a "Live Man" switch, actually a circuit breaker (normally open) 
that when I push it in by-passes power around all switches to the critical 
systems (fuel and spark).  I aborted a take-off  from a 2200 ft runway 
(after getting airborne) when the engine began to surge.  Only thing I did 
have time to do (which in hind sight was a waste of effort) was too push in 
the circuit breaker.  Of course, the odds of a surging engine being caused 
by a electrical problem is low - turned out it was the fuel map set too low 
for the higher engine rpms (this was when I was using an HALTECH EFI which 
you had to tune with laptop).

But, a good idea in my opinion since often use switches could possibly fail.

In any case, sounds like all the thought processes regarding what to do were 
well done  Land long and land hot if you have too - far better to go off the 
far end doing 20 mph than end up short on distance or airspeed - my opinion, 
of course.

Ed A
