After deciding on the Stec 55 Autopilot, that left only one possible vacuum 
instrument to deal with, the horizon.  It was pretty clear that a vacuum 
system to run one instrument  was not reasonable so I opted for the RC  Allen 
electric horizon at about $1500 and the B&C 20 amp standby alternator along 
with its solid state voltage regulator.   The B&C circuitry is designed to 
automatically turn the 20 amp alternator on if the main alt voltage drops.  
Appropriate warning lamps signal that this has taken place.  With the 28 V 
system, the 20 amp standby will run about everything  needed, even in hard 
IFR, without running down the battery which will be needed for hydraulic pump 
operation on landing.  Tha 20 amp alternator mounts on the same pad at the 
rear of the 550 as the vacuum pump and is a simple installation.    Wiring, 
too, is straight forward.  Bill and Tim at B&C are great to work with.  I 
still have a little work to do the get the warning lamps working with Jim 
Frantz's annunciator  since B&C system employs a flashing circuit as opposed 
to a steady  one.  
The other advantage is less plumbing behind the panel, and through the 
firewall.  Bob Young(RYoung03A@aol.com)  LC 30 N32BY  28 hours (and flying
