I had a similar problem with my 320 one year ago. Actions done: Alternator = checked and all the connections were OK.
Got very helpful advices from B&C.
In the end I changed the B&C Voltage (14V) regulator to the latest Revi= sion (guess it was at this time Rev C).

[BTW, I placed the new regulator Into the cockpit area. The defective one (= Rev A, 1995) was located firewall forward side (bad location for electronics= ...). The problem was solved and it works – since this improvement - v= ery stable.

Good luck!

<= SPAN STYLE=3D'font-size:11pt'>My volt 1 circuit breaker off the field of the a= ltenator keeps tripping when I cycle the gear.  This happens 100% of th= e time when going up and 20% going down.
 
What I have done:
 
The altenator was sent to Quality Aircraft in Tulsa and bench checked putti= ng out 75 amps under load.  The tech. stated that the altenator is as g= ood as you could hope for one to be.
 
51/2 amps was run through the circuit breaker and it did not trip.
 
Replaced the battery
 
checked for loose connections and worn wires.
 
This is in a io-550 Legacy with a 14 Volt system.  It has been runing = trouble free since March 2004 until one month ago.  Has anyone experien= ced this problem or have any ideas on what else I should check.  My A &= amp; P is out of ideas as am I.
 
The plane has a B & C voltage regulator which is said to be very depend= able and in most Lancairs.  At this time it is not suspected to be the = problem.
 
Thanks in advance for any input.
