My volt 1 circuit breaker off the field = of the altenator keeps tripping when I cycle the gear.  This happ= ens 100% of the time when going up and 20% going down.
 
What I have done:
 
The altenator was sent to Quality Aircraft in Tulsa and bench checked = putting out 75 amps under load.  The tech. stated that the altenator i= s as good 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 ru= ning trouble free since March 2004 until one month ago.  Has anyone ex= perienced this problem or have any ideas on what else I should check. = My A & P is out of ideas as am I.
 
The plane has a B & C voltage regulator which is said to be very d= ependable and in most Lancairs.  At this time it is not suspected to b= e the problem.
 
Thanks in advance for any input.
