Yeah, I ha= ve a very similar problem.  In summary, I have a Lancair designed and = installed electrical system in my Legacy.  The problem came after chan= ging the primary alternator at around 300 hours of flying.  After chan= ging the altenator, about 98% of the time that I would cycle the gear up th= e field breaker would pop.  Spikes were noted on occasion but after te= sting and replacing every suspected item, nothing was resolved.  A ban= d-aid approach suggested by my brother has resolved the problem and I have = had no tripped field breakers in over 50 hours.

=
It was suggested by those who desired to help that = I most likely had a bad ground or an intermittent connection somewhere.&nbs= p; I traced and checked and cleaned every connection, did not solve the problem.  I tested and found the voltage regulator to be good but= traded it out anyway, did not solve the problem.  Replaced the circui= t breaker as it had tripped so many times even though it still tested good,= did not solve the problem.  Traded out wires in case there was a wire= that was abraded in a location that I could not see that may be making int= ermittent contact, did not solve the problem.  After 14 months of disc= ussing and trying things suggested by Gary Lane at Lancair, I finally had m= y brother come out to the hanger to help me.  He suggested that the on= ly explanation he could come up with was a spike in the system.  What = was causing the spike was still a mystery but he found an item on the inter= net that he thought should solve the problem as its job is to absorb spikes= .  Well, it did work and as I said has for over 50 hours.  By the= way I tested and changed out more than this email would suggest.  I would guess that Gary Lane spent over 40 hours on the pho= ne with me while I would test items then come up with a plan to change out = something then test again all to no avail.
