I won't have a belt, but I still plan to run all the wires along and 
securely strapped to a motor mount support leg.  If I were running a 
belt, the only possibility of taking out the CAS would be at the wire's 
service loop at the top of the sensor.  But...
I'd like to suggest that if the belt takes out the CAS, in most cases 
you haven't lost much.  With the belt, you've also lost your water pump, 
so you're coming down much sooner than planned anyway.

I would be interested in some sort of 'waste-spark' system that could 
run the trailing plugs.  A mechanical system, with...I don't 
know...maybe magnetos on the flywheel... timed to always fire a late 
spark, even if it is a very week spark.  That way, the EC2 would still 
control the leading plug, and only in case of electrical system failure 
would the late firing and inefficient mechanical backup come into play.  
Fuel would be supplied with a single crude jet plumbed to the intake 
opening.  Power would be compromised, but there should be enough to 
maintain altitude.  When the electron pump gives up the ghost, this sort 
of system would reduce the battery load to a fuel pump, radios and panel 
lighting (plus a single EWP for me).
