My volt 1 circuit breaker off the field of the altenator
keeps tripping when I cycle the gear. This happens 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 is 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
runing trouble free since March 2004 until one month ago. Has
anyone experienced 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 dependable and in most Lancairs. At this time it is not
suspected to be the problem.
Thanks in advance for any input.
