2 corroded connectors limited voltage to the antenna.
Lesson learned: Just because it worked yesterday and nothing is visibly
wrong with your cables and connectors doesn't mean that they aren't the
culprit!

CHEAP lesson learned! My friend breathed a huge sigh of relief when they
said there wasn't anything wrong with the 430 itself.

A friend of mine has a 12v Garmin 430 that simply does not pick up the
satellites. It worked fine about 3 weeks ago (the last time he flew) but
now it fails to find any satellite signals. One avionics tech said that
it
had "lost it's almanac" and to pull it out and let it sit for a couple
hours
and it should pick up the satellites and work fine. No such luck. All
power and antenna connections are good and nothing has happened to the
airplane or the equipment since it flew last. Any ideas? Anybody ever
hear
of such a thing?

Thanks,
Jim
